ADC084S021CIMMX - 8-Bit 4-Ch 50-200ksps SAR ADC | Texas Instruments
ADC084S021CIMMX

ADC084S021CIMMX - 8-Bit 4-Ch 50-200ksps SAR ADC | Texas Instruments

The Texas Instruments ADC084S021CIMMX is a low-power, four-channel CMOS 8-bit analog-to-digital converter with a high-speed serial (SPI/QSPI/MICROWIRE-compatible) interface. Housed in a 10-pin VSSOP (also referenced as MSOP-10) package, it supports sample rates from 50 ksps to 200 ksps and operates from a single 2.7 V to 5.25 V analog supply. The device features four single-ended input channels selected via a hardware channel-select pin, an internal oscillator, and a successive-approximation register (SAR) architecture with no pipeline delay. An SAR (Successive-Approximation Register) ADC is a type of analog-to-digital converter that uses a binary search algorithm through an internal DAC to converge on the input voltage in N clock cycles for an N-bit result. SAR ADCs sit hierarchically under the broader categories of data acquisition -> data converters -> mixed-signal ICs -> power management and signal chain semiconductors. They are favored for their deterministic latency, low power, and small package size compared to pipeline or sigma-delta converters, making them ideal for multiplexed multi-channel low-speed measurements. Key features of the ADC084S021 include four single-ended analog inputs with an input voltage range of 0 V to V_A (the analog supply), 8-bit resolution with no missing codes, an integral nonlinearity (INL) of +/-0.2 LSB typical and +/-1 LSB maximum, and a signal-to-noise plus distortion (SINAD) figure above 49 dB. The serial interface operates up to 20 MHz at 5 V supply, and the part consumes only 1.7 mW at 200 ksps with a 3 V supply, dropping to microampere-level shutdown currents. Technically, the ADC084S021 uses a charge-redistribution SAR DAC and an input sample-and-hold, achieving low aperture uncertainty and good common-mode rejection. The wide 2.7 V to 5.25 V supply range and SPI compatibility with virtually any microcontroller DSP or FPGA makes integration straightforward. Typical applications include portable instrumentation, battery-powered sensor monitoring, process control loops, multichannel data loggers, and consumer audio/video equipment. Industrial temperature range of -40C to +85C ensures operation in factory and outdoor environments. Designers should provide adequate decoupling on VA and VDR (digital reference) pins and route the analog inputs away from noisy digital traces; the SAR core offers deterministic conversion latency, so input multiplexing does not introduce timing jitter. For noise reduction, oversampling and averaging in firmware are recommended for high-precision measurements.

ADC084S051CIMM - 8-Bit 4-Ch 500kSPS SAR ADC | Texas Instruments
ADC084S051CIMM

ADC084S051CIMM - 8-Bit 4-Ch 500kSPS SAR ADC | Texas Instruments

The Texas Instruments ADC084S051CIMM is a low-power, four-channel, 8-bit successive-approximation-register (SAR) analog-to-digital converter with a high-speed serial interface, housed in a 10-pin VSSOP (MSOP) package. It samples 200 to 500 ksps per channel, accepts four single-ended analog inputs, and outputs straight-binary data on a serial peripheral interface that is compatible with SPI, QSPI, MICROWIRE, and many common DSP serial ports. What is a SAR ADC? A successive-approximation-register analog-to-digital converter is a precision data-conversion architecture that uses a binary search algorithm and an internal sample-and-hold capacitor to digitize an analog input. SAR ADCs sit between flash converters (fastest, lowest resolution) and delta-sigma converters (highest resolution, slower) in the data-converter taxonomy, and they are preferred when both deterministic latency and 8-16 bit resolution are required. Key features of the ADC084S051 include a 2.7 V to 5.25 V single supply, four single-ended input channels multiplexed into one SAR core, and a 500 ksps aggregate sample rate. Power consumption is specified at 2.2 mW on a +3 V supply and 7.1 mW on a +5 V supply. The serial interface supports the standard SPI/QSPI/MICROWIRE modes, and the digital inputs are TTL-compatible, allowing direct connection to 3 V and 5 V microcontrollers without level shifters. The internal architecture is based on a charge-redistribution SAR with an inherent sample-and-hold, an on-chip reference, and an external clock. Conversion latency is deterministic at roughly 16 SCLK cycles, which simplifies DSP firmware timing. The reference can be driven from the supply or a more accurate external source, and the analog inputs are sampled at the end of the conversion, enabling true simultaneous-sampling of multiple channels when used with an external analog mux. Typical applications include portable data acquisition, multi-cell battery monitoring in industrial handhelds, sensor front-ends (temperature, pressure, strain-gauge bridges), process-control analog input modules, and consumer audio front-panel control. The wide 2.7 V-5.25 V supply range also suits 3.3 V MCU co-designs where rail noise and ground bounce are common. When designing with this part, dedicate a clean linear regulator to the AVDD pin and place 1 uF plus 0.1 uF decoupling capacitors as close to the supply pins as possible. The VSSOP-10 thermal pad (where present on similar TI parts) is not used here, but the exposed lead frame still benefits from a small copper pour for mechanical reliability in hand-held assemblies.

ADC084S101CIMMX

ADC084S101CIMMX - 4-Ch 8-Bit 1 Msps ADC | Texas Instruments

The Texas Instruments ADC084S101CIMMX is a low-power, four-channel CMOS 8-bit analog-to-digital converter with a high-speed serial interface, specified across a sample rate range of 500 ksps to 1 Msps, and housed in a 10-pin VSSOP (also referred to as 10-MSOP) package. The device operates from a single +2.7 V to +5.25 V supply and supports a -40C to +85C industrial temperature range, drawing only 3.6 mW of power at 500 ksps with a +3 V supply. The converter is based on a successive-approximation register (SAR) architecture with an internal 2.0 V reference, eliminating the need for an external voltage reference in most designs, while still allowing external reference drive for enhanced accuracy. An analog-to-digital converter (ADC) is a data-conversion integrated circuit that translates real-world analog signals into discrete digital codes for processing by microcontrollers, DSPs, or FPGAs. Within the broader taxonomy, an 8-bit SAR ADC sits between general-purpose ADCs (8 to 12 bits) and high-resolution ADCs (16 to 24 bits), occupying the speed-resolution sweet spot favored by instrumentation, motor control, and consumer designs. The ADC084S101CIMMX occupies the high-throughput end of this segment with throughput up to 1 Msps while maintaining low power consumption and a compact 10-pin VSSOP footprint suitable for space-constrained designs. Key features include four single-ended input channels multiplexed into a single SAR core, straight-binary output serial data compatible with SPI, QSPI, MICROWIRE and common DSP serial interfaces, and individual channel shutdown capability via the CS input. The internal reference (typically 2.0 V) provides ratiometric conversion accuracy, with the analog input range extending from 0 V to VDD when using a 5 V supply. The serial data interface reduces board-routing complexity and pin count compared to parallel-output ADCs of similar performance, which is essential for compact PCB layouts. Typical applications span industrial process control, multi-zone temperature monitoring, motor-current sensing, instrumentation digitizers, and portable battery-powered data acquisition where the low-power CMOS process and serial interface minimize both energy and board-area budgets. When designing with this part, ensure that the analog input does not exceed VDD or go below ground; bypass VDD with a 1 uF ceramic capacitor placed close to the supply pin and keep digital SCLK/CS/SDOUT traces short or impedance-controlled.

ADC08831IMM/NOPB - 8-Bit Serial I/O ADC, 1-Ch SAR, 8-VSSOP | TI
ADC08831IMM/NOPB

ADC08831IMM/NOPB - 8-Bit Serial I/O ADC, 1-Ch SAR, 8-VSSOP | TI

The Texas Instruments ADC08831IMM/NOPB is an 8-bit, single-channel, successive-approximation-register (SAR) analog-to-digital converter with serial I/O, housed in an 8-pin VSSOP (also called MSOP/TSSOP-equivalent slim) package. The device operates from a single +5 V supply (with extended tolerance per the part family), supports a sampling rate of approximately 181 ksamples/s, and exposes an NSC MICROWIRE-compatible 3-wire serial interface that requires only a few microcontroller I/O pins. It integrates an input track-and-hold amplifier and accepts analog input voltages from GND to VCC without requiring zero or full-scale adjustment. An SAR ADC (Successive Approximation Register analog-to-digital converter) is a comparator-based data converter that resolves each conversion one bit per clock cycle using a binary-search algorithm against a precision internal DAC. In the wider signal-chain taxonomy, the SAR architecture sits between flash converters (fastest, lowest resolution) and sigma-delta converters (highest resolution, lower bandwidth); it is favored for mid-resolution (8-18 bit) acquisition where low latency, simple serial I/O, and deterministic throughput are required. The ADC08831 family was originally released by National Semiconductor, whose data-converter portfolio was absorbed into Texas Instruments. Key features of the ADC08831IMM/NOPB include 8-bit resolution with no missing codes, 1 single-ended analog input channel (with a 2-channel input multiplexer option on the closely-related ADC08832), TTL/CMOS-compatible digital I/O, and very low power consumption suitable for battery-powered and portable data-acquisition systems. The serial digital data link needs only three wires (CS, CLK, DO), making it ideal for microcontroller-based designs where I/O count is at a premium. The converter uses a capacitive-charge redistribution SAR core with internal sample-and-hold, achieving a typical conversion throughput compatible with serial clocks up to several MHz. The device is a superior pin-compatible replacement for the legacy ADC0831/ADC0832 family, allowing direct drop-in upgrades in existing designs that require only 8-bit resolution. Typical applications include portable and battery-powered instrumentation, process-control analog front ends, digital panel meters, simple sensor digitizers (temperature, strain-gauge bridges via external amplifier), closed-loop servo feedback, and any microcontroller-based system needing a low-pin-count ADC. The /NOPB suffix confirms lead-free (Pb-free) RoHS-compliant termination. When designing with this part, place a 0.1 uF decoupling capacitor as close as possible to the VCC pin and provide a clean low-impedance analog ground. The serial interface is timing-sensitive - respect the t_CSL, t_SU, and t_HD parameters from the datasheet, and ensure the microcontroller SPI or bit-bang routine matches the MICROWIRE frame format (CS falling edge starts the conversion, MSB first on DO).

ADC08831IMX - 8-Bit Serial ADC 1-Ch 8-SOIC | Texas Instruments
ADC08831IMX

ADC08831IMX - 8-Bit Serial ADC 1-Ch 8-SOIC | Texas Instruments

The Texas Instruments ADC08831IMX is an 8-bit, single-channel, successive-approximation-register (SAR) analog-to-digital converter with a 3-wire serial interface, on-chip 2-channel analog input multiplexer, and integrated sample-and-hold, housed in an 8-pin SOIC (0.154 inch / 3.90 mm width) package. It accepts a single-ended analog input selected from two multiplexer channels and converts it to a serial output at a maximum sampling rate of 181 ksps. The device operates from a 4.5 V to 6.5 V analog supply and a 4.5 V to 6.5 V digital supply, making it suitable for both 5 V industrial rails and 3.3 V-5 V mixed systems. A SAR ADC is a type of data converter that performs a binary search through an internal resistor-ladder DAC to determine each digital code in a single conversion cycle; the architecture offers a deterministic latency and a strong trade-off between speed, power consumption, and cost for low-to-medium resolution measurements. Within the broader data-converter hierarchy, the ADC08831 sits below pipelined ADCs (used above ~10 MSPS) and above integrating ADCs (used for high-resolution DC measurements), occupying the 8-10-bit / 100-500 ksps niche where low cost and a small serial interface are dominant design constraints. Key features of the ADC08831IMX include 8-bit resolution with no missing codes, 1 input channel via the 2:1 input MUX, 3-wire MICROWIRE-compatible serial interface (CS, SCLK, DOUT), an internal sample-and-hold amplifier, and an industrial temperature range of -40 C to +85 C. The converter is fabricated on a low-power CMOS process, and the SOIC-8 surface-mount package is the same JEDEC-standard land pattern used across thousands of 8-pin analog ICs. Typical applications include portable and battery-powered instrumentation, digital panel meters, isolated sensor front-ends, and embedded MCU-based measurement systems where a 3-wire serial port pins out without an external address/data bus. The internal input MUX allows two single-ended sensors to share one converter, reducing BOM cost and PCB area. When designing with this part, observe the 4.5 V to 6.5 V supply constraint and the 181 ksps maximum throughput; at higher clock rates the aperture timing becomes critical, and the internal reference/VDD ratio should be considered against system noise. The serial interface is read-only (no SDI on the base ADC08831 variant), simplifying the protocol at the cost of register programming flexibility.

ADC08831IWM/NOPB

ADC08831IWM/NOPB - 8-Bit SAR ADC, 1-Ch, MICROWIRE I/F | TI

The Texas Instruments ADC08831IWM/NOPB is an 8-bit, single-channel, successive-approximation-register (SAR) analog-to-digital converter with serial MICROWIRE-compatible I/O, an integrated analog multiplexer, and an on-chip sample/hold, housed in a 14-pin SOIC (300-mil, 7.50 mm) wide-body package. Headline parameters include a maximum sampling rate of 181 kSPS per second and an operating temperature range of -40C to +85C (industrial). Originally introduced by National Semiconductor and now manufactured by Texas Instruments, this CMOS ADC targets cost-sensitive, space-constrained designs that require a single 5 V supply rail and a small serial footprint. A SAR ADC (successive-approximation-register analog-to-digital converter) is a type of data converter that uses a binary-search algorithm and an internal capacitive DAC to digitize an analog input in N clock cycles for N bits of resolution. SAR ADCs sit in the broader data-converter hierarchy between flash converters (faster but expensive) and sigma-delta converters (higher resolution but slower); they are valued for deterministic latency, moderate speed at low-to-moderate resolution, and low power consumption without external precision components. Key features of the ADC08831 include 181 kSPS maximum sample rate, a single analog input channel with integrated multiplexer tie-off options for differential operation, an on-chip sample-and-hold front end, and a National MICROWIRE-compatible serial interface that shares bus timing with SPI and TI MSP430 peripherals. The 14-SOIC wide-body package provides robust thermal performance for through-hole-compatible PCB footprints and remains compatible with industry-standard hand-soldering and automated SMT lines. Operationally, the part performs an internal conversion in approximately 8 I/O clock periods and uses an external reference voltage (typically tied to the analog supply for true ratiometric operation). The architecture is built on a CMOS process that minimizes active current draw while preserving low input-leakage performance, simplifying analog front-end design in embedded systems. According to TI product page for ADC08831, this device is intended for systems that need predictable, mid-resolution analog-to-digital conversion without the BOM cost of a precision op-amp front end. Typical applications for the ADC08831IWM/NOPB include digital panel meters, portable instrumentation, white-goods and appliance user-interface boards, simple process-control analog front ends (4-20 mA loop monitors), 8-bit MCU sensor acquisition channels (e.g., to PIC, 8051, or MSP430 cores), and battery-cell monitoring accessories. The wide SOIC package suits hand-soldered prototypes, educational kits, and low-volume industrial legacy retrofits where a true ratiometric 8-bit reference channel is acceptable. When designing with this device, place a 0.1 uF decoupling capacitor as close as possible to the analog supply pin and keep the analog input traces short and guarded by a ground pour to minimize digital coupling. The MICROWIRE interface shares lines with the system microcontroller's SPI peripheral, so designers should verify CPOL/CPHA mode matching and consider an external pull-up on the chip-select line if the host bus is released between transactions.

ADC08831IWMX/NOPB

ADC08831IWMX/NOPB - 8-Bit 181kSPS SAR ADC, 1-Ch, Serial | TI

The Texas Instruments ADC08831IWMX/NOPB is an 8-bit, single-channel, serial-I/O CMOS successive-approximation analog-to-digital converter (SAR ADC) with integrated multiplexer and sample/hold, housed in a 14-pin SOICW (wide-body) package with tape-and-reel packaging. Per the datasheet headline figures, the converter samples at 181 kSPS and communicates over the NSC MICROWIRE-compatible serial data interface, an industry-standard 3-wire serial protocol for low-pin-count microcontrollers. An SAR ADC is a member of the successive-approximation-register analog-to-digital converter family, which sits inside the broader ADC hierarchy (flash -> SAR -> sigma-delta -> integrating). The SAR architecture uses a comparator and a binary-weighted capacitor DAC to converge on the analog input one bit per clock cycle, offering an excellent trade-off between speed, resolution, and power for mid-rate, general-purpose applications between 10 kSPS and 1 MSPS. Key specifications include 181 kSPS maximum sampling rate, NSC MICROWIRE-compatible 3-wire serial interface (CS, SCLK, DO), single +5 V analog supply operation, and an industrial -40 °C to +85 °C operating temperature range. The integrated 1-channel input multiplexer plus sample/hold front end eliminates the need for external signal conditioning in many single-channel data-acquisition tasks. Pin-compatible variants provide flexibility: the SOIC-8 option (ADC08831IM/NOPB) drops to an 8-pin package for space-constrained designs. The ADC architecture relies on a charge-redistribution DAC with successive-approximation logic, allowing low power consumption without the latency of integrating ADCs. The wide SOIC-14 package offers superior thermal and mechanical robustness compared to the smaller SOIC-8 family, suiting industrial environments where temperature excursion and vibration are concerns. Typical applications include portable instrumentation, factory automation sensor digitizers, handheld multimeter signal paths, industrial process control, and consumer audio front ends. The 181 kSPS throughput covers mechanical-switch debouncing loops and many audio-bandwidth signals. The designer should route the analog and digital grounds as separate islands joined at a single star point near the ADC GND pin, and place the 0.1 µF VREF decoupling capacitor within 5 mm of the reference pin to preserve 8-bit linearity.

ADC08832IM

ADC08832IM - 8-Bit SAR ADC, 2-Ch MUX, 8-SOIC | Texas Instruments

The Texas Instruments ADC08832IM is an 8-bit successive-approximation analog-to-digital converter (SAR ADC) with a 3-wire serial interface and a configurable 2-channel input multiplexer, offered in an 8-pin SOIC (SO-8 wide, 0.150 inch) package. It operates from a single 5 V analog supply and consumes 8.5 mW typical power, with a maximum conversion time of 4 microseconds when the internal clock (fC) is driven at 2 MHz. The part is a pin-compatible upgrade to the legacy ADC0831/ADC0832 family, while adding the 2-channel addressable MUX and on-chip sample-and-hold. Background: A successive-approximation ADC (SAR ADC) is a sampled-data converter that uses a binary-search charge-redistribution DAC to converge on the input voltage one bit per clock cycle. SAR ADCs are widely chosen when low latency, deterministic throughput, and excellent DC accuracy are required - they sit in the converter hierarchy between flash converters (fastest, lowest resolution) and delta-sigma converters (highest resolution, lower bandwidth). A 2-channel input multiplexer allows a single ADC to digitize two analog sources sequentially, removing the need for two separate converter ICs in cost-sensitive designs. Key features include a 3-wire serial data link (CS, CLK, DO) that interfaces directly to COPS-family microcontrollers, PLDs, microprocessors, DSPs, and shift registers with no glue logic. The differential/single-ended input range spans from GND to VCC (typically 0 V to 5 V), no external zero or full-scale adjustment is required, and TTL/CMOS-compatible I/O simplifies 5 V and 3.3 V system integration. An on-chip track-and-hold front end captures fast or multiplexed signals without an external buffer. The architecture uses a capacitive-charge redistribution DAC matched against the input sample, with internal clock generation to control bit-trial timing. Digital readings are clocked out MSB-first through the DO pin, falling synchronously with the input clock transitions supplied to CLK. The internal oscillator is trimmed for the 4 us full-conversion target at fC = 2 MHz, and conversion results are ratiometric to the VREF applied to the MUX inputs - using VCC as the reference therefore yields a transfer curve of 1 LSB = VCC/256. Typical applications include industrial process-control data acquisition, portable instrumentation, point-of-sale terminals, and embedded sensor interfaces where a small-form-factor 8-bit converter is preferable to a discrete op-amp plus external ADC design. Designers upgrading legacy ADC0831/ADC0832 boards can drop this part into existing footprints for an immediate speed, power, and channel-count upgrade. When designing with ADC08832IM, follow a few key guidelines: place a 0.1 uF ceramic bypass capacitor within 5 mm of VCC, drive CLK with a clean CMOS clock rather than an RC source to avoid jitter-driven noise, and treat DO as a high-impedance output between conversions if sharing the bus with other peripherals. Optimum performance is achieved with ratiometric input sources (or a low-impedance reference) - the ratiometric topology means that absolute reference tolerance is absorbed into the application accuracy budget. This page synthesizes distributor stock and pricing, drop-in-compatible same-family alternatives (ADC08831IMX, ADC08831IMM/NOPB from the same datasheet family), and practical design notes that complement - rather than copy - the manufacturer datasheet.

ADC08832IMM - 8-Bit 2-Ch Serial I/O CMOS ADC | VSSOP-8 | Texas Instruments

The Texas Instruments ADC08832IMM is an 8-bit, 2-channel, successive approximation register (SAR) analog-to-digital converter with serial I/O, supplied in an 8-pin VSSOP (DGK) package. Operating from a single 4.5 V to 6.3 V analog supply, this CMOS ADC delivers a typical conversion time of 4 microseconds at a 2 MHz clock and integrates a 2-input analog multiplexer with input track-and-hold, allowing two single-ended signals to be digitized through a shared serial interface. An ADC (analog-to-digital converter) is a semiconductor that converts real-world analog voltages into discrete digital codes for processing by microcontrollers, DSPs, or FPGAs. SAR ADCs sample the input, hold it on an internal capacitor, and run a binary search via an internal DAC until the digital output matches the analog input; they are valued for determinism, low latency, and a single conversion per request. The ADC08832 family is positioned for cost-sensitive, space-constrained embedded designs that need 8-bit resolution and serial connectivity rather than high-throughput parallel conversion. Headline features include 8-bit resolution with no missing codes, a serial interface that requires only three wires (CS, CLK, DOUT) per the TI datasheet, an analog input range from GND to VCC, TTL/CMOS-compatible digital I/O, and an internal track-and-hold stage that eliminates the need for an external sample capacitor. The device is a drop-in upgrade for legacy ADC0831/ADC0832 designs and shares the same serial protocol, simplifying firmware migration. Architecturally the part combines a 2-channel input multiplexer, a sample-and-hold amplifier, a SAR core, an internal reference-free DAC, and a state-machine-driven serial output stage. Power dissipation is approximately 8.5 mW typical, and the converter operates across the -40 C to +85 C industrial temperature range, making it suitable for both indoor and moderately harsh environments. Typical applications include portable instrumentation, sensor signal digitization, battery monitoring systems, digital panel meters, process-control front ends, and any space-constrained embedded design that needs 8-bit accuracy on a single low-pin-count serial bus. Two multiplexer inputs allow designers to monitor a primary signal plus an auxiliary channel such as temperature or supply voltage with one ADC. The primary design tradeoff is resolution - 8 bits limits dynamic range to roughly 48 dB - so choose a 10/12-bit SAR if finer steps are required. The serial interface also imposes throughput limits compared to parallel ADCs; at 2 MHz CLK and 16 clocks per conversion, maximum throughput is around 125 ksps per channel in 2-channel mode. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that complement the manufacturer datasheet and help engineers evaluate the ADC08832IMM against modern alternatives.

ADC08832IMMX/NOPB

ADC08832IMMX/NOPB - 8-Bit 2-Ch 153kS/s SAR ADC | Texas Instruments

The Texas Instruments ADC08832IMMX/NOPB is an 8-bit successive approximation register (SAR) analog-to-digital converter with a 2-channel input multiplexer and 3-wire serial interface, delivered in an 8-pin VSSOP (MSOP-8) package. It samples at 153 kS/s with a 5V single supply, draws 8.5 mW (typical) of power in active mode and 3.0 mW in low-power mode, and provides ±1 LSB total unadjusted error with no missing codes over the operating temperature range. The X-suffix tape-and-reel variant, ADC08832IMMX/NOPB, shares identical silicon and pinout with the ADC08832IMM/NOPB (TSSOP-8), enabling PCB-compatible stocking under different reel volumes. A successive approximation ADC is a converter architecture that uses a binary search algorithm and an internal sample-and-hold to digitize an analog input in a fixed number of clock cycles. Within the data-converter hierarchy, an SAR ADC sits below pipelined and flash converters in raw sample rate but above delta-sigma in latency and DC accuracy per cycle. The 2-channel analog input multiplexer makes this part a compact solution for sensors, instrumentation, and embedded microcontrollers requiring a few channels of precision monitoring rather than a full multi-channel data-acquisition front end. Key differentiating features include the configurable 2-channel analog multiplexer, single 5V supply operation, TTL/CMOS-compatible I/O, 3-wire MICROWIRE-compatible serial interface, and a low-power mode that drops quiescent dissipation to 3 mW typical. The SAR architecture provides zero-latency conversions, making it well suited to multiplexed sensor acquisition where deterministic timing matters. From an architecture standpoint, the device uses a charge-redistribution DAC array controlled by successive-approximation logic. Conversion time at the maximum internal clock (fC = 2 MHz) is 4 µs maximum per the datasheet. The serial interface is pin-compatible with the legacy ADC0831/ADC0832 family, allowing straightforward upgrade paths in legacy designs that need only 2 input channels rather than the original single-channel topology. Typical applications include portable instrumentation, handheld battery-powered meters, microcontroller sensor front ends, factory automation modules, and embedded data loggers. The low-power mode and 5V single-supply operation align well with USB, automotive 5V rails, and battery-derived systems. When designing with this ADC, ensure the analog inputs stay within the input range of 0V to VREF and that VREF is stable - any noise on VREF directly couples to conversion accuracy. The CS/SS, CLK, and DO serial signals must be kept short to avoid digital coupling into the analog inputs.

ADC08832IN/NOPB - 8-Bit SAR ADC, 2-Ch, 8-PDIP | Texas Instruments

The Texas Instruments ADC08832IN/NOPB is an 8-bit successive-approximation-register (SAR) analog-to-digital converter with two input channels, packaged in an 8-pin PDIP (through-hole DIP) with a 0.300-inch (7.62 mm) row spacing. It supports a maximum sampling rate of approximately 153 ksps and operates from a single 4.5 V to 6 V supply, drawing only a few milliampere for low-power embedded designs. An SAR ADC is a converter architecture that uses a binary-search algorithm against an internal DAC to resolve each conversion in a fixed number of clock cycles; it combines low latency with deterministic throughput and is the workhorse of mid-speed data acquisition where successive samples need to be tightly time-stamped. The ADC08832 extends that architecture with an integrated 2-channel analog multiplexer and an on-chip sample-and-hold, eliminating the need for an external analog front-end switch and reducing board space, BOM cost, and total error budget. Key features include a serial NSC MICROWIRE-compatible digital interface that shares the bus with up to two additional ADC channels when cascaded, an industrial temperature grade of -40 °C to +85 °C, and a differential/single-ended input stage. Compared with parallel ADCs of the same era, the MICROWIRE serial interface reduces pin count and routes cleanly to modern microcontrollers, including MSP430 and Tiva C-Series devices. Typical applications include portable instrumentation, process-control analog input modules, factory automation sensor interfaces, and consumer audio level meters. The serial interface makes it well suited to compact boards where PCB real estate is constrained. When designing with this part, place the 0.1 µF supply-decoupling ceramic capacitor within 5 mm of the VCC pin and keep the analog input traces short and guarded with a ground plane. The through-hole PDIP package is preferred for breadboarding, hand-soldered prototypes, and legacy designs that still rely on through-hole assembly.

ADC08832IWM/NOPB

ADC08832IWM/NOPB - 8-Bit 2-Ch SAR ADC, MICROWIRE, SOIC-14 | TI

The Texas Instruments ADC08832IWM/NOPB is an 8-bit, 2-channel, successive-approximation-register (SAR) analog-to-digital converter with a 3-wire MICROWIRE-compatible serial interface, sample-and-hold, and an integrated 2-input analog multiplexer, housed in a 14-pin SOIC (IWM) package. It converts analog inputs to 8-bit digital words at sampling rates up to 153 kS/s with single 5V DC supply operation and a typical power dissipation of 8.5 mW. The part is a superior pin-compatible replacement for the legacy ADC0831/ADC0832 family. An SAR (successive-approximation-register) ADC is a type of analog-to-digital converter that uses a binary-search algorithm against an internal DAC to converge on the input voltage in N clock cycles, where N is the resolution in bits. SAR ADCs offer a compelling trade-off between speed, power, and accuracy, making them the workhorse of medium-speed data acquisition in embedded, industrial, and instrumentation systems. Within the broader taxonomy, the ADC0822 belongs to the family of data converters, which sit alongside amplifiers, references, and isolation as analog signal-chain building blocks. Key features include 2 single-ended analog input channels selected via internal multiplexer, ±1 LSB total unadjusted error, zero missing codes over the operating temperature range, TTL/CMOS-compatible I/O, an external clock up to 2 MHz for a maximum 4 microsecond conversion time, and a low-power shutdown mode drawing approximately 3.0 mW. The serial data exchange complies with the NSC MICROWIRE standard so it interfaces directly to COPS-family microcontrollers, PLDs, microprocessors, DSPs, and shift registers using only three I/O pins (CS, CLK, DO). The 14-pin SOIC package provides a familiar through-hole-style footprint in surface-mount form, simplifying retrofits onto existing ADC0831/ADC0832 designs. The device architecture combines an input multiplexer, sample-and-hold, switched-capacitor DAC, comparator, SAR, and serial output logic on a single CMOS die. Conversion is initiated on the CS falling edge and completed in 4 microseconds at the maximum 2 MHz clock, after which the MSB-first serial word is clocked out on the DO line. Single 5V supply operation eliminates the need for negative rails, while the wide digital logic compatibility (TTL/CMOS compatible I/O) allows direct connection to 5V or 3.3V microcontrollers using simple level-shifting if required. Typical applications include industrial process control analog front ends, portable battery-powered instrumentation, multi-channel sensor monitoring in HVAC/RSSI-based systems, PLC analog input modules, and embedded data loggers. The integrated multiplexer makes it particularly attractive where two sensors share a single converter channel. When designing with this device, place a 0.1 microfarat decoupling capacitor as close as possible to the VCC pin and keep analog and digital grounds joined at a single point under the IC. The CS pin must be taken low to initiate conversion, and clock edges should be kept clean to avoid spurious DO transitions.

The Texas Instruments ADC088S052CIMTX is a low-power, eight-channel CMOS 8-bit successive-approximation-register (SAR) analog-to-digital converter with throughput rates specified from 200 kSPS to 500 kSPS, packaged in a 16-pin TSSOP (MT) and specified over the -40C to +105C industrial temperature range. The device accepts up to eight single-ended analog inputs (IN0-IN7) through an analog input multiplexer, with each channel digitized by an internal track-and-hold circuit followed by the SAR core. The output serial data is straight binary and is compatible with SPI, QSPI, MICROWIRE, and many common DSP serial interfaces, allowing direct connection to a wide range of microcontrollers and digital signal processors. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that transforms continuously variable analog voltages into a digital code proportional to the input. SAR ADCs use a binary-search algorithm implemented in switched-capacitor DAC hardware to perform one bit per clock cycle, delivering deterministic latency (one conversion-cycle delay) and excellent DC accuracy with no pipeline-induced distortion. The 8-bit, 8-channel SAR topology sits within the broader hierarchy: SAR ADC -> successive-approximation ADC -> ADC -> data converter -> mixed-signal IC -> semiconductor. This ADC family specifically targets low-channel-count multiplexed applications where simplicity, low power, and small package are valued over raw conversion speed or higher resolution. Key features of the ADC088S052 family include independent analog (V_A) and digital (V_D) supply pins that allow the analog and digital sections to operate from different rails - useful for isolating digital switching noise from sensitive analog inputs in mixed-signal boards. The serial interface is mode-configurable and operates as a standard SPI/QSPI/MICROWIRE slave, simplifying firmware development on virtually any modern microcontroller. An internal reference or an externally applied reference may be selected, depending on system accuracy requirements. Typical applications include multi-channel sensor monitoring in industrial process control, battery-cell voltage monitoring in battery-management systems, portable and handheld instrumentation, and general-purpose data-acquisition front ends. The eight input channels are particularly efficient when several sensor signals (temperature, pressure, position) must be sampled from a single board. When designing with this ADC, decouple V_A and V_D separately near the IC pins, keep analog traces short and guarded from digital switching, and ensure the SPI clock does not exceed the converter's specified maximum at the chosen throughput rate.

ADC088S102CIMTX - 8-Ch 1MSPS 8-Bit SAR ADC | Texas Instruments

The Texas Instruments ADC088S102CIMTX is an 8-channel, 8-bit successive-approximation-register (SAR) analog-to-digital converter with throughput rates from 500 kSPS to 1 MSPS, housed in a 16-pin TSSOP (PW) package. The device operates from a single 2.7 V to 5.5 V analog supply, accepts up to eight single-ended input signals on IN0-IN7, and serializes conversion results on a single SPI/QSPI/MICROWIRE-compatible output. An 8-bit ADC is a low-resolution successive-approximation analog-to-digital converter that converts an analog input voltage into one of 256 discrete digital codes using a binary-search charge-redistribution algorithm. SAR ADCs are sample-and-hold based, deterministic in latency (one conversion per clock), and require no anti-alias filter window below Nyquist. ADC converters sit hierarchically inside data-converter ICs -> ADC/DAC -> mixed-signal semiconductors, providing the bridge between analog sensors and digital microcontrollers, FPGAs, or DSPs. Key specifications include ±1 LSB maximum DNL (no missing codes), ±1 LSB maximum INL, 8 single-ended analog inputs with an analog input multiplexer, a true-differential sample-and-hold input structure, an external CONVst conversion-start input, and a wide digital-supply range of 1.6 V to V_A. Power consumption scales linearly with throughput, enabling designers to throttle sample rate to reduce system energy. Industrial-grade variants support -40 °C to +105 °C ambient operation, making the part suitable for harsh environments. Architecturally, the ADC088S102 uses a charge-redistribution DAC array combined with a high-speed comparator and successive-approximation register. The eight analog channels are scanned sequentially through an internal analog multiplexer; any subset of channels can be enabled via the configuration register to maximize power savings. The serial interface is fully compatible with standard SPI, MICROWIRE, and QSPI controllers, simplifying integration with virtually any modern microcontroller. Typical applications include industrial process control, multi-zone temperature monitoring, HVAC fan/valve position feedback, optical module monitoring, consumer appliance sensor aggregation, and general-purpose 8-channel data acquisition boards. The wide supply range and small package also suit battery-powered IoT sensor nodes. Designers should drive each analog input with a low-source-impedance buffer, route AGN D as a star/ground plane, and decouple V_A and V_D with a 1 µF plus 0.1 µF capacitor pair within 5 mm of the pins. The external serial clock should be kept below 25 MHz to keep total throughput within the 1 MSPS spec.

ADC08B200CIVS - 8-bit 200MSPS ADC w/ Buffer | TI 48-TQFP

The Texas Instruments ADC08B200CIVS is a high-speed 8-bit analog-to-digital converter sampling at 200 MSPS with an integrated 1K deep capture buffer, supplied in a 48-pin TQFP (7x7 mm) package. The pipeline-style core is built on the proven ADC08200 architecture with internal track-and-hold and is optimized for low power consumption. It features a single analog input channel with TTL/CMOS-compatible digital outputs and a separate output supply pin supporting 2.7V to 3.3V logic levels. A high-speed analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous-time analog voltage into discrete digital codes at very high sample rates. ADCs sit at the boundary between the analog front-end and the digital processing block of a system and are organized in a hierarchy by resolution (8-bit, 10-bit, 12-bit, etc.) and sample rate. The 8-bit, 200 MSPS tier addresses applications such as video digitizers, digital oscilloscopes, IF sampling, and digital data-acquisition front ends where sub-ENOB resolution is acceptable in exchange for high throughput and low latency. ADC08B200 belongs to a class of pipeline ADCs internally followed by a small capture buffer that decouples the analog conversion rate from downstream memory bandwidth. Key features of the ADC08B200CIVS include 200 MSPS guaranteed sampling rate, an internal 1K-sample FIFO capture buffer, single +3.0 V analog supply operation, and a straight-binary output format. The device also integrates a programmable duty-cycle stabilizer for the input clock and supports both external reference and internal reference modes. Differential and single-ended analog input topologies are accommodated through the on-chip input network. The architecture combines a 8-bit flash-style quantizer with timing interpolation and an on-chip deep capture buffer that can hold up to 1024 conversion results. This lets a downstream processor read back conversions at a much slower clock than the ADC sample clock, simplifying PCB routing and relaxing memory bandwidth requirements in radar pulse, ultrasound, or pre-trigger oscilloscope architectures. Typical applications include digital oscilloscopes, waveform digitizers, IF signal processing in communications receivers, radar pre-processing, CCD imaging systems, and consumer video capture. The 48-TQFP surface-mount package and industrial -40C to +105C temperature range make it suitable for both lab instruments and ruggedized field equipment. When designing with ADC08B200CIVS, route the analog input with controlled-impedance 50 ohm traces and place the input coupling capacitors as close as possible to the device pins. The separate VDR output supply pin should be decoupled independently from the analog supply so switching noise on the digital outputs does not couple back into the analog front end.

The Texas Instruments ADC08D1000CIYB is a high-performance, low-power dual 8-bit analog-to-digital converter (ADC) capable of 1.0 GSPS per channel (dual mode) or 2.0 GSPS interleaved (single mode), housed in a 128-pin HLQFP package (NNB / 20x20 mm). It features dual differential inputs, an on-chip sample-and-hold, and a folding-interpolating architecture that reduces power consumption while maintaining excellent dynamic performance up to the Nyquist frequency. An 8-bit ADC is a data converter that translates an analog input voltage into a discrete 8-bit digital code, providing 256 distinct quantization levels - high-speed 8-bit ADCs are typically used in digital oscilloscopes, radar, EW receivers, and test instrumentation. ADC08D1000CIYB sits in the hierarchy: flash/folding-interpolating ADC -> analog-to-digital converter -> data acquisition IC -> mixed-signal semiconductor. Its dual 1 GSPS sample rate combined with DDR LVDS outputs enables direct interfacing with FPGAs and ASICs without external deserialization. Key specifications include 7.4 ENOB (effective number of bits) at 500 MHz input, SNR of 48 dBFS typical, and SFDR of 65 dBc at 250 MHz input frequency. The device operates from 1.9 V analog and 1.9 V digital supplies (typical), supports interleaved single-channel mode for 2 GSPS acquisition, and includes an integrated 1:2 demultiplexer that halves the output data rate for easier interfacing. The folding-interpolating architecture uses an internal folding amplifier array with interpolation to produce 8-bit codes from a reduced comparator count, lowering both power (1.8 W typical at full rate) and input capacitance compared with a pure flash ADC of equivalent speed. Each channel can be powered down independently for portable applications. Typical applications include high-end digital oscilloscopes, radar and electronic-warfare receivers, cable-headend DOCSIS infrastructure, and real-time wideband spectrum analysis. Direct LVDS interfacing eliminates external level shifters, simplifying FPGA-based capture designs. When designing with this ADC, the analog input network must present a 100-ohm differential termination with proper 50-ohm matching to preserve SFDR at high input frequencies. Decoupling requires 1uF plus 0.1uF ceramic capacitors on each supply pin, placed within 5 mm of the package, and the exposed thermal pad must be soldered to a 4-layer PCB with at least 16 thermal vias.

The ADC08D1520 family targets wideband signal acquisition where low latency and high spurious-free dynamic range are critical. An analog-to-digital converter (ADC) is a semiconductor device that converts continuous analog signals into discrete digital codes at a sample rate determined by its clock input. Within the converter hierarchy, the ADC08D1520 belongs to the high-speed flash/folding-and-interpolating ADC class, sitting under the broader categories of data converters, signal chain ICs, and finally power management/signal processing semiconductors. High-speed 8-bit ADCs are commonly used as front ends for digital oscilloscopes, radar receivers, and software-defined radio where multi-GHz analog bandwidth is required. Key features include selectable dual-channel (1.5 GSPS each) or single-channel (3.0 GSPS interleaved) operating modes, an LVDS-compatible DDR output bus, on-chip test-pattern generator for system debug, programmable clock phase adjustment for sampling alignment, and a selectable 1:1 or 1:2 output demultiplexer. Power consumption is specified at approximately 1.6 W per channel at full sample rate, which is competitive in the ultra-high-speed ADC category. The device uses a folding-and-interpolating architecture with an internal reference ladder and sample-and-hold front end, enabling wide analog input bandwidth (>2 GHz typical) while maintaining 8-bit linearity at multi-GSPS rates. The DDR LVDS output interface simplifies capture into Xilinx and Altera FPGAs without external buffering logic. Typical applications include digital oscilloscopes, radar and lidar signal processing, wideband satellite and microwave receivers, software-defined radio platforms, mass spectrometry, and high-speed data acquisition systems.

The Texas Instruments ADC08D500CIYB is a dual, low-power, high-performance CMOS analog-to-digital converter that digitizes analog signals to 8-bit resolution at sampling rates up to 500 MSPS per channel, or 1.0 GSPS in interleave mode. The part is housed in a 128-pin HLQFP (NNB) package measuring 20 mm x 20 mm, with a single +1.9 V ±0.1 V supply requirement. An analog-to-digital converter is an integrated circuit that samples continuous-time analog waveforms into the binary, register-blocked digital domain at a fixed sampling rate; the ADC08D500 family specifically targets the high-speed, low-power segment used in communications, test equipment, and radar signal chains. The product type hierarchy is ADC > data converter > mixed-signal IC > semiconductor. The ADC08D500 family is also commonly referred to as a flash ADC with folding and interpolating architecture, a two-step sub-ranging ADC, or a high-speed pipeline ADC derivative. Key features include internal sample-and-hold, choice of SDR or DDR output clocking, an interleave mode that doubles sampling rate, multiple ADC synchronization capability, guaranteed no missing codes, a serial interface for extended control, fine adjustment of input full-scale range and offset, and duty-cycle corrected sample clock. These capabilities make the device a preferred option for dual-channel wideband digital oscilloscopes and direct RF downconversion chains. The device uses a folding and interpolating architecture with an internal calibration engine, achieving low-latency digital conversion without the deep pipeline delay seen in pipelined ADCs. This makes it well suited for time-domain applications such as radar pulse measurement and triggering applications where deterministic latency matters more than raw SNR. Typical applications include radar and LIDAR digitizer front-ends, automated test equipment, digital oscilloscopes, communications basestation receivers, and high-speed signal analyzers. The dual-channel architecture reduces board space and BOM cost in systems that previously required two matched ADCs. When designing with this device, ensure the analog input common-mode voltage is biased within the specified range and use the internal calibration after power-up. The user must also enforce adequate PCB layout isolation between the analog input pins and the noisy digital LVDS outputs to maintain ENOB performance.

ADC1001CCJ - 10-Bit µP Compatible SAR ADC, 20-CDIP | Texas Instruments

The Texas Instruments ADC1001CCJ is a 10-bit CMOS successive approximation register (SAR) analog-to-digital converter with a single differential input channel, 4.6 kSPS sampling rate, and parallel data interface, housed in a 20-pin ceramic DIP (CDIP) through-hole package. Key headline specifications are: 10-bit resolution, single +5V supply operation, and 4.6 kSPS throughput, with on-chip track-and-hold and clock generator. An SAR (Successive Approximation Register) ADC is a class of data converter that uses a binary search algorithm and an internal DAC to converge on the input voltage one bit per clock cycle. SAR ADCs occupy the middle of the converter hierarchy between flash converters (fastest, lowest resolution) and sigma-delta converters (slowest, highest resolution), offering a favorable trade-off of speed, accuracy, and simplicity. The ADC1001 specifically is pin-compatible with the legacy ADC0801 8-bit family, allowing direct 10-bit upgrade on existing 8-bit socket boards, and reads its 10-bit result as two 8-bit bytes (left-justified, high byte first) so it can connect to 8-bit microprocessors without external glue logic. Key features of the ADC1001CCJ include differential analog input with on-chip sample-and-hold, guaranteed no-missing-codes operation, ratiometric or absolute voltage reference input, and TTL/CMOS-compatible digital outputs. The 20-CDIP ceramic package provides 0C to 70C commercial operating range and excellent long-term reliability for legacy through-hole industrial designs. The device uses a charge-redistribution DAC array combined with a successive-approximation register and comparator to perform the conversion. Conversions are initiated by a falling edge on WR/RDBC (pin 6), and the result is read as two successive bytes from the parallel data bus DB0-DB9. Internal clock generation requires only an external RC network on pins 19 and 4. Typical applications include process control data acquisition boards, legacy 8-bit microprocessor measurement front-ends, panel-meter and instrumentation digitizers, and battery-cell voltage monitors. The ceramic CDIP package is especially valued in military, aerospace, and high-reliability industrial systems where plastic DIP and SMD alternatives are not accepted. When designing with this ADC, ensure the analog input does not exceed VREF+0.3V or go below GND-0.3V to avoid latch-up. Decouple VCC (pin 20) with 1uF tantalum in parallel with 0.1uF ceramic placed within 5mm of the supply pin, and provide a clean low-impedance VREF trace to preserve the converter's 10-bit linearity.

It converts the analog input signal into 10-bit binary-coded digital words while operating from a 3.0 V to 5.25 V analog supply, with all digital inputs and outputs CMOS compatible. A standby mode allows a reduction of the device power consumption when conversion is not required. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that samples a continuous analog input voltage and quantizes it into a discrete digital code. A 10-bit ADC produces 1024 discrete codes (LSB = full-scale / 1024), and at 20 MSPS the converter can accurately capture baseband video and intermediate-frequency signals well below the Nyquist frequency of 10 MHz. In the broader system hierarchy, the ADC1002S020 sits between an analog front-end (amplifier/filter) and a digital back-end (ASIC, FPGA, or DSP), occupying the data-acquisition tier of the signal chain alongside sample-and-hold circuits, voltage references, and clock generators. Key features include 10-bit resolution, 20 MSPS maximum sampling rate, a single 3.0 V to 5.25 V analog supply with CMOS-compatible digital I/O, an integrated pipeline architecture, and a power-saving standby mode. The parallel data interface simplifies connection to FPGAs, microcontrollers, or display controllers without requiring a high-speed serial deserializer. The device uses a pipelined architecture with an internal reference ladder to deliver consistent linearity across the input range, and differential analog inputs maximize common-mode rejection for noisy environments. The 20 MSPS sample rate provides ample headroom for standard-definition digital video and IF digitization. Typical applications include professional video digitization, IF signal sampling, instrumentation, and general-purpose data acquisition. The wide analog supply range (3.0 V to 5.25 V) lets the part coexist with 3.3 V and 5 V system rails. The integrated standby mode and CMOS I/O further simplify power-constrained portable designs. When designing with this ADC, ensure the analog input drive network is low-impedance at the Nyquist frequency to preserve SFDR.

ADC1002S020HL/C1:1 - 10-bit 20MSPS Video ADC, 32-LQFP | Renesas

The Renesas (formerly NXP/IDT) ADC1002S020HL/C1:1 is a 10-bit high-speed pipelined Analog-to-Digital Converter designed for professional video and high-speed data acquisition applications. It delivers sampling rates up to 20 MHz with single 5.25 V operation, packaged in a 32-pin LQFP (5x5 mm, SOT401-1). The converter accepts differential analog inputs and produces CMOS-compatible parallel digital outputs at 10-bit resolution, with a single-channel architecture optimized for low power dissipation. What is a pipelined ADC? A pipelined Analog-to-Digital Converter is a type of high-speed ADC that uses multiple cascaded low-resolution stages to convert an analog signal into digital code. Each stage samples the input, performs a coarse conversion, and passes the residue to the next stage, enabling simultaneous sampling and conversion that achieves sampling rates from a few MHz up to hundreds of MHz. Pipelined ADCs sit within the broader hierarchy of ADC -> data converter -> mixed-signal IC -> semiconductor, and are widely preferred for video, imaging, communications, and instrumentation where speed and resolution must coexist. The ADC1002S020 features a differential analog input, a parallel CMOS digital interface, and a standby mode that reduces device power consumption when conversions are not required. Its architecture supports sampling rates up to 20 MSPS, making it well matched to standard-definition video digitisation, CCD imaging front-ends, and IF-sampling communications receivers. The single 5.25 V supply simplifies power-tree design versus parts that require separate analog and digital rails. Technically, the part uses a resistive-ladder DAC and pipelined quantizer topology, providing 10-bit linearity for video-grade applications. Operating temperature spans -20C to +75C (commercial grade), suiting indoor equipment, test instruments, and embedded video capture modules. The CMOS-compatible parallel interface simplifies connection to FPGAs, ASICs, and DSPs without level translation. Typical applications include professional video digitizers, CCD/CIS imaging front-ends, IF-stage digitizers in communications receivers, ultrasound beamforming preprocessing, and general-purpose high-speed data acquisition systems. The 32-LQFP footprint is widely accepted on standard 4-layer PCB stacks with no exotic routing. When designing with this part, ensure the analog input is bandwidth-limited to meet Nyquist criteria at 20 MSPS, decouple AVDD and DVDD with separate 100 nF + 10 uF networks near the pins, and avoid running digital switching traces under the analog input pin to preserve SNR.

The Texas Instruments ADC10030CIVT/NOPB is a 10-bit, 30 MSPS, 125 mW pipelined analog-to-digital converter with internal sample-and-hold, housed in a 32-pin TQFP (7x7 mm) package. It accepts a single analog input channel, uses a parallel data interface, and runs from a single +3.3V analog supply while producing standard CMOS-compatible digital outputs. The converter targets high-density, low-power signal acquisition where 10-bit dynamic range and 30 megasamples per second are sufficient. An analog-to-digital converter (ADC) is a mixed-signal data acquisition IC that converts continuous-time analog voltages into discrete digital codes for downstream DSP, microcontrollers, or FPGAs. The pipelined architecture used in the ADC10030 family (pipeline ADC -> sub-ranging ADC -> Nyquist ADC -> data converter -> mixed-signal IC -> semiconductor) achieves high sampling rates at moderate resolution by processing successive stages on different clock edges, balancing latency, area, and power. This hierarchy positions the ADC10030 between low-cost SAR ADCs (slow, high-resolution) and high-speed flash ADCs (fast, low-resolution, expensive). Key features of the ADC10030CIVT/NOPB include 10-bit resolution, 30 MSPS guaranteed sampling rate, typical 125 mW power dissipation from a single 3.3V supply, internal sample-and-hold, pipelined architecture with on-chip reference, single-ended analog input, and an industrial -40C to +85C operating temperature range. The 32-pin TQFP-32 (7x7 mm) is a thin plastic quad flat pack designed for surface-mount manufacturing, with a gull-wing lead profile and an exposed thermal pad-style heat slug to the silicon die. Typical applications for the ADC10030CIVT/NOPB include IF/baseband digitization in communications receivers, CCD/CIS imaging signal chains, ultrasound and medical imaging front-end cards, portable and battery-powered instrumentation, and general-purpose data acquisition systems. The single 3.3V supply and 125 mW dissipation make it appropriate for thermal- and power-constrained embedded designs. When designing with this part, place a ferrite bead and decoupling capacitor bank within 5 mm of AVDD/DRVDD pins, keep the analog input trace short and guarded, and provide a clean low-jitter sampling clock. The internal reference requires an external bypass capacitor; do not inject switching noise into REF pins.

ADC1003S030TS/C1

ADC1003S030TS/C1 - 10-Bit 30MSPS Video ADC | NXP | SSOP-28

The NXP ADC1003S030TS/C1:1 is a 10-bit resolution, 30 MSPS (mega-samples per second) single-channel analog-to-digital converter from the ADC1003S030/040/050 family, housed in a 28-pin SSOP (Shrink Small Outline Package) with 5.3 mm body width per the SOT341-1 / MO-150 outline. The part integrates an on-chip voltage regulator, allowing operation from a single +3.0 V to +3.6 V analog supply while delivering a parallel CMOS-compatible digital output bus, and it consumes approximately 95 mW of power at 30 MSPS with a 2.5 V p-p analog input range. The C1/TS suffix indicates the SSOP-28 industrial-grade package variant, qualified over 0 C to +70 C commercial temperature range. What is a video ADC? A video analog-to-digital converter (video ADC) is a specialized high-speed ADC optimized for digitizing analog video signals in real time. The 10-bit resolution class is the broadcast industry standard (ITU-R BT.601 / SMPTE 259M) because it provides 1024 quantization levels - enough dynamic range to encode luma and chroma information with visually lossless fidelity after gamma correction. Compared to general-purpose ADCs, video ADCs include internal clamping, gain stages, and often an integrated reference, reducing external component count for video capture cards, broadcast equipment, and professional camera systems. The ADC1003S030 family uses a pipelined flash architecture with a 2.5 V p-p full-scale input range. The integrated voltage regulator lets the digital and analog sections share a single 3.3 V rail, simplifying PCB layout. A 30 MSPS sampling rate is sufficient for SDTV (480i/576i) and CIF-resolution digital video, and the same footprint scales to 40 MHz (ADC1003S040) and 50 MHz (ADC1003S050) members for higher-bandwidth video formats. Typical applications include professional video digitizers, broadcast equipment, surveillance DVRs, medical imaging front-ends, and high-speed data acquisition cards. Pin compatibility with the ADC1003S040 and ADC1003S050 means designers can drop in a higher-speed part if more bandwidth is needed without re-laying the board. When designing with this ADC, provide a low-impedance analog input path with 75-ohm termination (the standard for video), use a stable low-jitter sampling clock, and bypass the on-chip regulator with a 100 nF plus 10 uF capacitor pair on the analog supply pin.

ADC1003S030TS/C1:1

ADC1003S030TS/C1:1 - 10-Bit 30MSPS ADC | 28-SSOP | NXP

The NXP ADC1003S030TS/C1:1 is a 10-bit, 30 MSPS (mega-samples per second) analog-to-digital converter (ADC) housed in a 28-pin SSOP (Shrink Small Outline Package) and is part of NXP's ADC1003S030/040/050 high-speed low-power ADC family targeted at professional video and other high-speed signal conversion applications. This converter integrates an on-chip voltage regulator, a single analog input channel, and a parallel digital data interface that simplifies connection to FPGAs, DSPs, and microcontrollers for high-throughput data capture. An ADC (Analog-to-Digital Converter) is a semiconductor device that converts continuous analog voltage signals into discrete digital codes suitable for processing, storage, or transmission. The ADC1003S030TS/C1:1 belongs to the successive-approximation/pipeline class of high-speed converters and is part of the broader data-converter hierarchy: ADC -> data converter -> mixed-signal IC -> integrated circuit -> semiconductor. The on-chip regulator removes the need for an external clean analog supply, simplifying board design while improving power-supply rejection in noisy system environments such as industrial video backplanes. Key features of the ADC1003S030TS/C1:1 include 30 MSPS sampling rate, 10-bit resolution over a parallel bus, single-channel (1 input) architecture, an integrated voltage regulator reference, and low power consumption optimized for professional video digitisation where a streaming digital data path of 30 million samples per second per channel is required. Operating from a -40 C to +85 C industrial temperature range, this ADC is designed to support the demanding thermal profiles of broadcast video equipment and similar industrial imaging applications. From an architectural perspective, the device combines an input track-and-hold amplifier, a flash-like quantization core, an internal voltage reference, and parallel output latches in a single die. According to the manufacturer's description, the resolution ladder structure (resistance ladder) and regulator arrangement produce a stable transfer function even across the full -40 C to +85 C operating window, simplifying calibration effort in production test. Typical applications include professional video acquisition and broadcast equipment, medical imaging front ends, industrial machine-vision cameras, ultrasound receivers, and high-speed data acquisition cards. The parallel interface and 28-SSOP footprint also suit retrofit designs where engineers are upgrading legacy 8-bit or 10-bit video ADC boards. When designing with this device, place a 0.1 uF decoupling capacitor as close as possible to the analog supply pins and obey the standard SSOP-28 land pattern. The ADC1003S030/040/050 family shares the same pinout across speed grades, so the ADC1003S030 (30 MSPS) can be socket-compatible with the ADC1003S040 (40 MSPS) or ADC1003S050 (50 MSPS) variants when a higher sample rate is needed. This page consolidates pricing tiers, drop-in alternatives inside the same 28-SSOP footprint, and design notes beyond the information shown on typical distributor listings.
