AD977CN - 16-Bit 100 kSPS ADC | Analog Devices
The Analog Devices AD977CN is a 16-bit, 100 kSPS successive-approximation analog-to-digital converter in a 20-pin through-hole DIP package. It operates from a single 5 V supply, supports unipolar and bipolar input ranges, and is designed for precision signal acquisition where 16-bit resolution is useful without the throughput demands of a flash converter. The AD977 family also includes the faster AD977A, which is specified at 200 kSPS. An ADC is a data-acquisition IC that converts an analog voltage into a digital code. A successive-approximation ADC, commonly called a SAR ADC, performs conversion by comparing the unknown input with an internally generated trial voltage and progressively refining a binary approximation. The AD977CN therefore belongs to the ADC, data-converter, signal-processing, and semiconductor hierarchy, with relevance to industrial measurement, instrumentation, communications, and embedded control systems. The converter provides a 16-bit resolution, a 100 kSPS throughput rate, and single 5 V operation. Its input architecture includes unipolar ranges of 5 V and 4 V and bipolar ranges of 5 V and 3.3 V, according to the verified manufacturer product information. Available interface choices and power-management behavior should be confirmed in the manufacturer datasheet for the exact AD977CN ordering configuration. Maximum power dissipation is listed as 100 mW in the supplied verified description, while a power-down mode is also indicated. Because this is a SAR ADC, the input is sampled and converted through a sequence of internal comparison decisions rather than a parallel flash architecture. This makes the converter suitable for control loops, sensor interfaces, test equipment, and communication front ends that need moderate speed and high resolution. The AD977CN is a 100 kSPS device, whereas AD977A is the 200 kSPS family variant; selecting the correct suffix is important when sample rate is a hard system constraint. AD977CN applications include industrial process monitoring, precision instrumentation, communications receivers, data-acquisition cards, and embedded measurement systems. In each case, the analog front end must establish the correct input range, provide suitable reference and drive circuitry, and account for acquisition time before conversion. The serial or parallel data interface and required digital support components should be selected from the datasheet and system clock plan. A key design consideration is the input and reference network. Incorrect source impedance, inadequate filtering, or unsuitable bypass capacitance can degrade effective resolution and conversion accuracy. The 5 V supply should be decoupled close to the device, and the analog input should be protected against overvoltage and transients. Because the AD977CN is listed as obsolete in one verified distributor-style source, new designs should confirm lifecycle status, availability, and any supported migration path before committing to production. This page consolidates the verified Analog Devices family description, distributor identity, package information, and practical replacement guidance for AD977CN. It also distinguishes confirmed facts from parameters that require the exact manufacturer datasheet, helping engineers evaluate the obsolete 16-bit SAR ADC without treating unverified electrical values as production specifications.

Operating temperature range is -20 C to +75 C (commercial grade), and the device is supplied in tube packaging as the standard shipping format. The internal architecture uses a resistive-ladder DAC combined with a comparator and SAR logic to perform 8 successive approximations per conversion cycle. Each conversion takes approximately 8 clock cycles, after which the parallel output bus (DB0-DB7) presents the conversion result until the next sample. The sleep-mode pin allows the user to gate the converter's analog/digital supply current when the application is idle. Typical applications include video digitisation, general-purpose data acquisition, image processing front-ends, and IF/baseband sampling in communications receivers. It is also used in battery-powered portable instrumentation where the low-power sleep mode reduces quiescent current. The wide input range (2.7 V to 5.5 V) supports single 3.3 V and 5 V system rails. When designing with this device, ensure the analog input bandwidth and source-impedance driving network satisfies the datasheet acquisition-time requirement to avoid gain error. Use a low-jitter clock to keep aperture uncertainty low at 40 MSPS, and decouple AVDD/DVDD independently with 100 nF ceramic capacitors placed close to the supply pins. Sleep-mode timing must be respected if the part is duty-cycled to save power.

ADC0801S040TS/C1:1 - 8-bit, 40MSPS Video ADC | NXP | 20-SSOP
The NXP ADC0801S040TS/C1:1 is an 8-bit universal analog-to-digital converter (ADC) optimized for video and general-purpose high-speed sampling applications, housed in a 20-pin LSSOP (TSSOP-equivalent) package. The device samples at up to 40 MSPS and accepts analog input signals in the 2.7 V to 5.5 V range, converting them into 8-bit parallel binary-coded digital words. According to the manufacturer datasheet, the converter uses a successive-approximation (SAR) architecture with an internal reference and supports CMOS/TTL-compatible digital I/O. An analog-to-digital converter is a semiconductor device that converts continuous analog signals into discrete digital codes for processing by microcontrollers, DSPs, FPGAs, or display pipelines. Within the broader signal-chain hierarchy, the ADC0801S040 belongs to the SAR-ADC family (Successive-Approximation Register ADC) -> ADC -> data converter -> mixed-signal IC -> integrated circuit. SAR ADCs deliver deterministic latency, single-cycle conversion, and a low external-component count, making them well suited for multiplexed or sample-on-demand systems rather than continuous-stream pipeline applications. Key performance features include 8-bit resolution, 40 MSPS maximum sampling rate, single-channel single-ended analog input, parallel digital output interface, and a low-power sleep mode for portable or duty-cycled designs. The ADC0801S040 operates over the industrial -20 C to +75 C temperature range and supports a single 2.7 V to 5.5 V analog supply that is shared with the digital I/O domain, simplifying PCB power design. Typical applications include professional video digitizers, composite-video or component-video capture front-ends, LCD/DLP projection engines, IF-stage digitizers, general-purpose high-speed data acquisition, and digital oscilloscope front-ends. The 20-SSOP footprint is footprint-compatible with the larger ADC0804S040 family, simplifying layout reuse between 8-bit and higher-resolution variants. When designing with this part, ensure the analog input is bandwidth-limited to less than half the sampling rate (Nyquist) and place a small RC anti-alias filter immediately at the analog input pin to limit wideband noise and kick-back from the internal sampling capacitor.
ADC0802LCWMX/NOPB - 8-Bit 10kSPS SAR ADC | Texas Instruments
The Texas Instruments ADC0802LCWMX/NOPB is a CMOS 8-bit successive-approximation analog-to-digital converter (SAR ADC) with one differential input channel, 10 kSPS sampling rate, and parallel data interface, housed in a 20-pin SOIC (0.295", 7.50 mm width) package. It operates from a single +5 V supply, accepts a 0 V to 5 V analog input range when used with a 5 V reference, and provides ratiometric operation when paired with the on-chip clock and an external 2.5 V reference such as the LM336. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that converts a continuous analog voltage into a discrete digital code. The successive-approximation register (SAR) architecture uses a binary-search algorithm with an internal sample-and-hold and a precision DAC, performing one conversion in N clock cycles where N is the resolution (8 cycles here). SAR ADCs sit within the data-converter hierarchy under ADC/DAC > mixed-signal IC > semiconductor. They are widely used in microcontroller-compatible applications because of their deterministic conversion time, ease of interface, and lack of pipeline latency. Key features include a differential potentiometric 256R-style ladder that supports ratiometric conversion with no missing codes, an on-chip clock generator (no external clock required), a differential analog input for rejection of common-mode noise, and direct μP compatibility with the NSC800 and INS8080A control bus through three-state output latches. The /CS and /RD inputs function like memory read strobes so the converter appears as memory or I/O to the processor. The ADC0802 architecture uses a chopper-stabilized comparator and a 256R-resistor ladder network derived from the classic ADC0801 family, achieving ±1 LSB linearity with no zero adjustment required. The internal clock generator is set by a single external RC network, simplifying BOM and PCB layout compared to discrete or pipelined ADC designs. The 5 V single-supply operation removes the need for negative rails typical of older bipolar ADC designs. Typical applications include process-control front ends, panel meters and digital voltmeters, portable instrumentation and battery monitors, μP-based data acquisition boards, and legacy industrial sensor interfaces where 8-bit resolution and 10 kSPS throughput are sufficient. The /NOPB suffix denotes a lead-free, RoHS-compliant device in tape-and-reel packaging. When designing with this device, reserve adequate board space for the SOIC-20 thermal/exposed lead frame and follow TI's recommended decoupling (0.1 µF close to VCC) and reference layout. Because the converter is ratiometric, supply and reference noise track each other and largely cancel, but a low-noise reference such as the LM336-2.5 is recommended for absolute-voltage measurements.

It supports a 5V analog supply, delivers up to ~50 ksps conversion throughput, and offers a serial I/O interface (Microwire/SPI-compatible) for compact microcontroller connections. An SAR (Successive Approximation Register) ADC is a type of analog-to-digital converter that uses a binary-search algorithm against an internal precision DAC to resolve the input voltage in N clock cycles. SAR ADCs sit in the hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. They are valued for deterministic latency, low latency per conversion, and DC accuracy without the pipeline delay of higher-speed flash or pipelined architectures, making them ideal for multiplexed sensor reading and motor control feedback. Key features include 8-bit resolution, single +5V supply operation, on-chip sample-and-hold, internal 2.5V (or 5V) reference option, and a serial data output that reduces pin count versus parallel-output ADCs. The SOIC-14 wide-body package offers improved thermal performance over SOIC-8 in continuous-sampling applications and supports industrial temperature grade (-40C to +85C). Typical applications include portable instrumentation, process control loops, battery monitoring, and embedded sensor interfaces where board space is at a premium. The serial interface allows direct connection to microcontrollers without bus-sharing glue logic. When designing with this device, ensure the analog input bandwidth and source impedance are within the track-and-hold acquisition requirements (typically <= 10 kohm source for full accuracy). A 0.1 uF decoupling capacitor placed close to the VCC pin is mandatory; larger bulk capacitance on the analog rail further reduces reference-induced conversion noise.

ADC08032CIWMX - 8-Bit 2-ChHS Serial I/O SAR ADC | Texas Instruments
The Texas Instruments ADC08032CIWMX is an 8-bit successive-approximation-register (SAR) analog-to-digital converter with two differential/double-ended input multiplexers and a high-speed serial I/O interface, housed in a 14-pin SOIC (DWM) package. It supports two analog input channels selectable through an internal MUX and provides serial output data through a 3-wire SPI-/QSPI-/MICROWIRE-compatible interface. The converter operates from a single +5V analog supply with an absolute maximum rating of 6.5V. What is an SAR ADC? A successive-approximation-register analog-to-digital converter is a sampling ADC architecture that uses a binary-search algorithm against an internal DAC to determine each bit of the conversion result, one bit per clock pulse. SAR ADCs sit in the data-converter hierarchy between flash converters (fastest, lowest resolution) and sigma-delta converters (highest resolution, lowest speed). They deliver an attractive balance of 8-18 bit resolution, low to moderate sampling rates up to a few MSPS, deterministic latency, and very low power consumption, making them a workhorse for embedded measurement, industrial control, and precision sensor front-ends. Key features include two differential analog input channels with true-differential track-and-hold, software-configurable unipolar/bipolar input ranges, on-chip track-and-hold, a serial data interface that reduces board-routing complexity versus parallel-output SAR ADCs, and an external-clock SAR architecture that allows conversion rates up to the device's specified sample rate. The ADC08032 family is widely deployed in legacy industrial, instrumentation, and process-control designs. Typical applications include two-channel data acquisition systems, multi-sensor monitoring with channel scanning, portable/battery-powered measurement equipment, and embedded instrumentation that requires a serial interface to a microcontroller with limited GPIO. The differential input capability makes it suitable for bridge sensors, thermocouples with cold-junction compensation, and ratiometric measurements. When designing with this device, place 0.1uF decoupling capacitors as close as possible to the AVDD and DVDD pins, ensure the reference voltage source has low output impedance at the conversion-clock frequency, and verify timing margins on SCLK, CS, and DOUT against your microcontroller's SPI-rated peripheral. The serial interface eliminates bus-contention issues common to parallel-output ADCs.

ADC08038CIWMX - 8-Bit 8-Ch SAR ADC w/Serial I/O | Texas Instruments
The Texas Instruments ADC08038CIWMX is a 8-bit, high-speed, successive-approximation-register (SAR) analog-to-digital converter with 8 analog input channels, internal sample-and-hold, integrated multiplexer, on-chip voltage reference, and MICROWIRE-compatible serial interface, housed in a 20-pin SOIC (IWM) wide-body package. An 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 convert an analog input voltage to a digital code, one bit per clock cycle. SAR ADCs sit within the broader hierarchy of data converter -> ADC -> successive approximation architecture -> precision mixed-signal IC, and they are widely preferred when low-latency deterministic conversion, modest resolution, and small package footprint are simultaneously required. The 8-input multiplexer allows a single ADC core to digitize up to eight sensors or signals, reducing BOM area and cost in multi-channel systems. Key features include 8-bit resolution, 8 analog input channels with analog multiplexer, internal sample-and-hold, on-chip reference, MICROWIRE/serial-compatible data interface, and single +5V analog supply with digital supply separate for low-noise operation. The wide-body 20-SOIC package offers robust thermal performance and is suitable for both industrial and commercial environments. The ADC08038 uses a charge-redistribution SAR architecture with an internal capacitor DAC and a precision comparator. Its throughput of up to approximately 1 MSPS (depending on MPN variant and clock), combined with an internal reference and 8-channel analog multiplexer, makes it well-suited for multi-sensor acquisition in compact designs where a single ADC must serve multiple analog sources. Typical applications include multi-channel data acquisition systems, process control and instrumentation, industrial sensor monitoring, portable battery-powered instrumentation, automotive sensor interfaces, and embedded microcontroller analog front-ends. The internal reference eliminates the need for an external reference IC in many designs, simplifying the BOM and reducing PCB area. When designing with this device, ensure the analog and digital grounds are tied at a single point to minimize digital noise coupling into the analog front-end. Decouple VCC and VREF pins with 0.1 uF capacitors placed as close as possible to the IC pins, and use a low-impedance analog input path to preserve the 8-bit accuracy.

ADC0803LCN - 8-Bit SAR ADC, 10kSPS, 20-DIP | Texas Instruments
The Texas Instruments ADC0803LCN is a CMOS 8-bit successive-approximation analog-to-digital converter with one differential analog input, packaged in a 20-pin PDIP (through-hole DIP) and rated for 10 kSPS sampling over a single 4.5 V to 6.3 V supply. What is an SAR ADC? A successive-approximation register (SAR) analog-to-digital converter resolves an analog input to N bits by comparing the input against an internal DAC and walking a binary search through the registers on each clock edge. SAR ADCs sit in the broader hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. They trade the speed of flash ADCs and the channel density of delta-sigma ADCs for low power, moderate latency, and a simple parallel/serial digital interface, which is exactly why the ADC0803 family has remained in legacy microprocessor designs for decades. Key feature highlights include 8-bit resolution with ±1 LSB linearity (the "LCN" grade), a built-in differential potentiometric 256R ladder, on-chip clock generator, and three-state outputs that interface directly to 8080/6800 control buses. Power consumption is typically below 10 mW, and a differential analog input lets the device reject small ground offsets in noisy industrial buses. The internal architecture combines a chopper-stabilized comparator, a successive-approximation register, a switched-capacitor DAC formed by the 256R ladder, and a parallel output latch. The 256R topology provides inherent monotonicity without trimming and gives a stable reference ladder that does not require a precision external reference, simplifying the BOM versus discrete ADC designs. Typical applications include legacy industrial process-control loops, panel-meter readouts, battery monitoring for handheld equipment, and any 8080/6800/Z80 microcomputer analog front end where a low-cost, easy-to-interface 8-bit converter is acceptable. The differential input is also useful for thermocouple or bridge-type sensor readouts where one terminal sits above ground. When designing with the ADC0803LCN, treat VREF/2 as the analog mid-scale reference; use a 10 kHz external clock or the internal RC oscillator and add 10 nF + 100 nF decoupling close to the supply pins. The through-hole 20-DIP footprint makes this part easy to breadboard but limits mounting density compared to modern SMD ADC alternatives. This page synthesizes current distributor availability, parametric drop-in alternatives, and practical layout guidance that goes beyond the raw datasheet to support both legacy maintenance and new 8-bit analog designs.
ADC0804LCJ - 8-Bit µP-Compatible SAR ADC, 20-DIP | Texas Instruments
The Texas Instruments ADC0804LCJ is an 8-bit successive-approximation analog-to-digital converter (SAR ADC) housed in a 20-pin ceramic DIP (CDIP) package, designed for direct interface with microprocessor buses without external buffering. It supports a single-ended analog input with on-chip differential potentiometric ladder architecture and offers an on-chip clock generator and on-chip sample-and-hold, making it a complete 8-bit A/D solution for legacy industrial and instrumentation designs. Key specifications include a 10 kSPS maximum sampling rate, ±5 VDC or 0–5 VDC input range with 5 V supply, and a parallel data interface. An SAR ADC (Successive Approximation Register Analog-to-Digital Converter) is a type of data converter that uses a binary search algorithm to converge on the correct digital representation of an analog input signal over N successive clock cycles for an N-bit result. SAR ADCs sit in the broader hierarchy of ADC architectures (SAR, Flash, Pipelined, Sigma-Delta) and are favored for moderate-resolution, moderate-speed conversions with low power consumption and deterministic latency, making them ideal for embedded control loops and battery-powered instruments where Sigma-Delta complexity would be excessive. The ADC0804LCJ features a built-in clock derived from an external RC network, eliminating the need for an external oscillator. The differential reference inputs (REF/2 or full-span reference) support ratiometric operation, and the tri-state outputs enable direct connection to µP data buses with a minimum of glue logic. Operating temperature range is -40C to +85C for the LCJ-grade ceramic DIP package. The LCJ suffix denotes the ceramic DIP package and the -40C to +85C industrial temperature range, distinguishing it from the LCN (plastic DIP, 0–70C) and LCWM (SOIC-20 wide-body) variants. Typical applications include legacy industrial process control front ends, sensor signal conditioning digitization, panel-meter and digital voltmeter data acquisition, and µC or microprocessor-based data acquisition boards where 8-bit resolution and simple timing are sufficient. The 20-DIP through-hole form factor also makes the LCJ an easy-to-prototype choice for breadboard designs and educational lab equipment.

ADC0804LCN - 8-Bit µP Compatible SAR ADC | Texas Instruments
The Texas Instruments ADC0804LCN is a CMOS 8-bit successive-approximation analog-to-digital converter with a single differential analog input channel, housed in a 20-pin PDIP (N) package. It delivers 8-bit resolution with ±1 LSB INL and ±1 LSB DNL, runs on a single +5 V analog supply, and uses a separate VREF/2 pin for span scaling so the full-scale range tracks the system reference. According to the manufacturer datasheet, the converter integrates an on-chip clock generator (no external crystal required) and a sample-and-hold front end, simplifying external analog design. What is a SAR ADC? A successive-approximation register (SAR) ADC is a type of analog-to-digital converter that resolves one bit per clock cycle using a binary-search algorithm against an internal precision DAC. SAR ADCs occupy the middle of the converter hierarchy: slower than flash ADCs but more accurate per LSB, faster than sigma-delta ADCs at the same resolution. They are the workhorse choice for 8-16 bit, 1 MSPS-class data acquisition in microprocessorbased systems where deterministic latency and ease of digital interfacing matter more than raw speed. Key features include 0 V to 5 V analog input range with single-ended or pseudo-differential operation, on-chip track/hold, three-state outputs designed for direct 8080 / 6800 / generic microprocessor bus interface, and a low typical ICC of 1.9 mA at 25 °C with CS = 5 V. The CS input is assumed to bracket the WR strobe input, so timing is dependent on the WR pulse width. The 20-pin PDIP format makes the LCN variant well suited to through-hole prototyping, educational boards, and replacement of legacy sockets. Typical applications include 8-bit data loggers, process-control front ends, digital-panel-meter replacements, microcontroller analog-input expansion, and legacy industrial system upgrades. The wide operating temperature range of -40 °C to +85 °C supports industrial control environments, and the device remains in production for replacement of mature designs. The LCN suffix denotes the 20-pin plastic DIP industrial temperature version. When laying out the ADC0804LCN, place the analog input and VREF decoupling capacitors as close as possible to the analog pins and isolate analog ground from digital ground at a single point under the part. The internal clock frees the designer from crystal selection but the external CLK R / CLK RC components must be chosen to keep the conversion rate around 640 kHz for the LC version. Designers should remember that ADC0804 is the active-High RD variant; ADC0803 is identical except for an active-Low RD output polarity.

ADC0804LCWMX - 8-Bit µP-Compatible ADC, 10kSPS, 20-SOIC | TI
The Texas Instruments ADC0804LCWMX is a CMOS 8-bit successive-approximation analog-to-digital converter (SAR ADC) offering one differential analog input channel, parallel digital interface, and 10 kSPS sampling rate in a 20-pin SOIC (0.295 inch, 7.50 mm width) wide-body surface-mount package. The device uses a differential potentiometric ladder architecture similar to the classic 256R products and is designed to interface directly with 8080-type microprocessor buses via three-state output latches. It operates from a single +5 V analog supply (with an optional -5 V negative reference input) and supports ratiometric conversion. An SAR (successive-approximation-register) ADC is a sampled-data converter that compares the input voltage against an internal DAC using a binary-search algorithm, producing one conversion result per N clock cycles for N bits of resolution. SAR ADCs sit in the converter hierarchy between flash ADCs (faster, more power, expensive) and sigma-delta ADCs (slower, higher resolution, integrated digital filtering); they are favored when low latency, no pipeline delay, moderate resolution (8-16 bit), and simple microprocessor interfacing are required. The ADC0804 family is a benchmark of legacy microprocessor-compatible data acquisition. Key features of the ADC0804LCWMX include 1 LSB integral nonlinearity (linearity error), a 135 ns memory access time, a built-in clock generator (RC-timed), and continuous or triggered conversion modes. Differential analog voltage inputs improve common-mode noise rejection. The wide-body SOIC footprint and operating range of 0 °C to +70 °C suit legacy industrial control, instrumentation, and embedded designs. According to TI datasheet SNAS538, the device can be used as a stand-alone ADC or with a microprocessor data bus. Typical applications include legacy 8-bit microprocessor analog front ends (8080, 8051, NSC800), industrial process controllers, battery chargers, panel meters, and any design requiring ratiometric A/D conversion with simple parallel readout. The differential inputs allow direct connection to bridge sensors, thermocouple amplifiers, or ground-referenced signals using a mid-supply reference. When designing with the ADC0804LCWMX, select an external resistor-capacitor pair (RCLK, CCLK) to set the conversion clock between 100 kHz and 1.46 MHz; the internal state machine derives the SAR clock from this master. Add 0.1 µF decoupling on VCC and ensure the reference ladder is bypassed at the REF pin for stable conversions. This device is pin-compatible with the broader ADC0801/0802/0803/0805 family. This page synthesizes distributor stock, drop-in alternatives, and design considerations for the ADC0804LCWMX not consolidated in the TI datasheet, helping procurement and engineering teams select with full context.
ADC0804S030TS/C1 - 8-bit 30MSPS ADC | SSOP-28 | NXP
The NXP ADC0804S030TS/C1 is a single-channel, 8-bit resolution analog-to-digital converter with a maximum sampling rate of 30 MSPS, housed in a 28-pin SSOP (5.30 mm body width, MO-150 / SOT341-1) package. It belongs to the ADC0806030/040/050 family of 8-bit high-speed, low-power ADCs designed for professional video applications, with sibling members ADC0804S040 and ADC0804S050 offering 40 MSPS and 50 MSPS respectively. The converter uses a single +3.3 V analog supply and a separate digital supply pin, providing the noise isolation required for high-speed video digitisation. An ADC (Analog-to-Digital Converter) is a mixed-signal integrated circuit that samples continuous-time analog voltages and converts each sample into a discrete digital code word. Flash, pipelined, and successive-approximation (SAR) are the three dominant ADC architectures; the ADC0804S030TS/C1 family uses a flash-style architecture optimised for video rates. Within the broader taxonomy, this part is an 8-bit video ADC, sitting beneath video decoder and image processing pipelines and above the analog front-end anti-alias filter in a typical video signal chain. Key features include 30 MSPS maximum conversion rate, 8-bit resolution with single analog input, low-power CMOS architecture, and a commercial-grade operating temperature range of 0 C to +70 C. The single 8-bit parallel output bus interfaces directly with FPGAs, ASICs, or video processors without glue logic. Internal reference and sample-and-hold circuitry simplify board design versus discrete ADC solutions. Architecturally, the device uses an array of 2^8 = 256 high-speed comparators clocked by an internal clock generator, which is why the part achieves sub-microsecond conversion rates but consumes more power than SAR converters of equivalent resolution. The 30 MSPS ceiling makes the part suitable for standard-definition video digitisation rather than HD video. Typical applications include professional video digitisation cards, SDTV/SD-SDI capture front-ends, broadcast equipment, security and surveillance DVRs, and medical imaging preprocessing boards. Pair this ADC with a video amplifier front-end and an FPGA-based video processor to build a complete SD video capture pipeline. When designing with this part, route the analog input with controlled-impedance 50 ohm microstrip and place the input coupling capacitor within 5 mm of the AIN pin to preserve bandwidth. Use separate analog and digital ground planes joined at a single point beneath the IC to minimise switching noise coupling into the analog input.

ADC0804S030TS/C1:1 - 8-bit 30MSPS Video ADC SSOP-28 | NXP
The NXP ADC0804S030TS/C1:1 is a single-channel, 8-bit, 30 MSPS parallel-output analog-to-digital converter designed for high-speed, low-power video and imaging data acquisition. Packaged in a 28-pin SSOP (Shrink Small Outline Package, MO-150 / SOT341-1 outline, 5.30 mm body width), it converts a single-ended analog input into an 8-bit parallel CMOS/TTL-compatible digital word at sample rates up to 30 million samples per second, while consuming roughly 90 mW from a single 5 V analog and 5 V digital supply. The part is qualified to commercial screening (operating temperature 0 °C to +70 °C), making it suitable for consumer video, broadcast graphics, and instrumentation applications. An Analog-to-Digital Converter (ADC) is a mixed-signal integrated circuit that samples a continuous-time, continuous-amplitude analog waveform and quantises each sample into a discrete digital code. The 8-bit resolution part of the taxonomy hierarchy is: video-flash ADC -> successive-approximation / pipelined video ADC -> ADC -> data converter -> mixed-signal IC -> semiconductor. 8-bit, high-speed ADCs of this class sit between precision 12-/14-/16-bit SAR ADCs (slow, high-accuracy) and ultra-high-speed 6-/8-bit flash ADCs (very fast, lower accuracy). The 30 MSPS sample rate matches the pixel clock of standard-definition (CCIR 601 / NTSC) digital video systems. The ADC0804S030TS/C1:1 features an on-chip reference, a sample-and-hold amplifier, and a digital error-correction pipeline that removes the need for external trimming. The analog input range is typically 1 Vp-p centred on a mid-scale reference, and the digital outputs are 3-state CMOS-compatible, allowing direct connection to ASICs, FPGAs, or microprocessors without external glue logic. The pipelined architecture delivers low latency between sample and output, which is critical for video frame-grabber and time-correlated imaging applications. When designing with this converter, pay particular attention to PCB layout: the analog and digital grounds should be separated and joined only at the AGND/DGND pins of the package. Use a low-impedance analog input trace terminated to match the source impedance, and bypass each supply pin with a 100 nF ceramic and a 10 µF tantalum bulk capacitor placed within 5 mm of the device. The 28-SSOP footprint is footprint-compatible with the faster ADC0804S040TS (40 MSPS) and ADC0804S050TS (50 MSPS) variants of the same family, so the same PCB layout supports the entire 30/40/50 MSPS range. Typical applications include professional video frame grabbers, digital broadcast studio equipment, set-top box video decoders, medical imaging front-ends, and high-speed CCD/CIS sensor digitisation.
