MAX1121EGK+ - 8-Bit 250Msps ADC with LVDS Outputs | Maxim

The Analog Devices (formerly Maxim Integrated) MAX1121EGK+ is a monolithic 8-bit, 250Msps analog-to-digital converter (ADC) optimized for outstanding dynamic performance at high intermediate frequencies up to 500 MHz, housed in a 68-pin QFN (10x10 mm) package with exposed thermal pad. It operates from a single 1.8V supply, draws approximately 410 mW, and delivers LVDS-compatible outputs that ease routing into FPGAs and high-speed ASICs. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that samples a continuous analog waveform and converts each sample into a discrete digital code. Pipelined ADCs, like the MAX1121, use a cascade of low-resolution stages and digital error correction to achieve very high sampling rates (hundreds of Msps) while keeping power dissipation reasonable. Within the power management and signal chain hierarchy, this part sits at: ADC -> data converter -> mixed-signal IC -> semiconductor IC. Key features include a guaranteed 250 Msps conversion rate, 1.8V single supply operation, internal bandgap reference, parallel LVDS outputs, a flexible input stage optimized for high-IF undersampling up to 500 MHz, and low spurious content for wideband applications. The wide input bandwidth allows direct sampling of IF signals in software-defined radio and cable infrastructure, eliminating downconversion stages. The pipelined architecture provides 1.2 GHz analog input bandwidth, an SINAD of approximately 49 dB at 100 MHz input, and excellent spurious-free dynamic range (SFDR) suitable for multi-carrier receivers. On-chip clock duty-cycle correction and LVDS timing alignment reduce FPGA capture complexity. Typical applications include cable modem downstream receivers, digital predistortion feedback paths in wireless base stations, handheld spectrum analyzers and test equipment, and high-IF undersampling in software-defined radio (SDR) platforms where wide bandwidth and low power matter. When designing with this ADC, follow the reference layout in the manufacturer datasheet, keep analog and LVDS return paths separated, and provide a clean low-noise clock to achieve the rated SNR. Decoupling must include 0.1 uF and 10 uF ceramic capacitors close to each supply pin.

MAX1121EGK+TD

MAX1121EGK+TD - 250Msps 8-Bit ADC, LVDS, QFN-68 | Maxim

The Maxim Integrated (now Analog Devices) MAX1121EGK+TD is a 1.8V, 8-bit, 250 Msps analog-to-digital converter (ADC) with LVDS outputs for wideband applications. Housed in a 68-pin QFN-EP package (10 mm x 10 mm, 0.9 mm height, MO-220, package code G6800-4), this pipelined ADC is optimized for outstanding dynamic performance and operates from a single 1.8V analog supply with separate digital output supply, drawing approximately 250 mW at full speed. An ADC is a data converter that translates continuous analog signals into discrete digital codes for downstream DSP, storage, or transmission. The 8-bit, 250 Msps class sits in the converter hierarchy between general-purpose successive-approximation ADCs (<= 1 Msps) and high-resolution pipelined ADCs (>= 14 bits). Pipelined ADCs use multiple low-resolution flash stages per clock cycle to achieve very high sampling rates while keeping per-stage power dissipation low - the MAX1121's pipeline architecture delivers 250 Msps with 1.8V operation, a balance targeting wideband IF sampling rather than instrumentation precision. Key features include an input bandwidth above 400 MHz, a signal-to-noise-plus-distortion ratio (SINAD) above 46 dB at 100 MHz input, an effective number of bits (ENOB) above 7.2 bits, and LVDS-compatible digital outputs that ease interfacing with FPGAs and dedicated clock-data-recovery (CDR) blocks. The 68-pin QFN-EP package provides an exposed thermal pad for low junction-to-PCB thermal resistance, which is critical at 250 Msps full-speed operation. Differential analog and clock inputs reject common-mode noise and support direct-coupled IF sampling without baluns in many layouts. The MAX1121 uses a proprietary multi-stage pipeline with on-chip track-and-hold, internal reference, and output data serializers. The chip provides separate analog (AVDD) and digital output (OVDD) supplies to isolate switching noise from sensitive analog inputs - a common technique in high-speed ADC design. The LVDS interface reduces EMI and enables longer board traces to the receiver ASIC or FPGA at hundreds of MHz parallel rates. Typical applications include digital predistortion (DPD) feedback paths in cellular base-station power amplifiers, IF sampling for software-defined radios and radar receivers, medical ultrasound beamformers, cable infrastructure digitizers, and test-and-measurement digitizers. The 8-bit resolution is well matched to DPD loops that only require accurate amplitude/phase estimation rather than full signal reconstruction. When designing with this device, allocate substantial ground plane area under the exposed pad and use solid via stitching between the analog and digital domains. Keep analog and clock traces length-matched within a few hundred mils. Maintain the AVDD/OVDD split with separate decoupling networks and verify that downstream LVDS receivers operate within their common-mode range.

The converter integrates six differential or 12 single-ended input channels, an on-chip clock generator, and a flexible SPI-compatible serial interface, simplifying multi-channel data-acquisition front ends. A sigma-delta ADC is a type of oversampling converter that uses a high-frequency modulator and digital decimation filter to achieve very high resolution (commonly 16-24 bits) at the cost of input bandwidth. In the hierarchy of data-converter ICs, sigma-delta ADCs sit alongside SAR (successive-approximation) and pipeline ADCs, favored for precision DC and low-frequency measurement where noise rejection and linearity matter more than speed. The MAX11291 belongs to Maxim's low-power precision ADC family, targeting portable, industrial, and sensor-conditioning applications where SNR per milliwatt is critical. Key differentiating features include 100 dB SNR at 60 Hz with 17.5 kHz bandwidth, 2.5 kHz fully integrated conversion, ultra-low 1.4 mA typical supply current, integrated low-drift reference and PGAs with up to 32x gain, and built-in temperature sensor. The device offers simultaneous 50 Hz and 60 Hz line-rejection at 60 Hz data rate, ensuring clean readings in industrial environments. Internally, the device pairs a fourth-order modulator with a SINC1 + SINC3 selectable digital filter, configurable through the SPI interface for trade-offs between resolution and settling time. The WLP-36 (Wafer-Level Package, 3.5x3.5 mm, 0.4 mm pitch) provides minimal PCB footprint for space-constrained wearables and IoT edge nodes. AEC-Q100 qualification is NOT confirmed in verified sources. Typical applications include 4-20 mA loop-powered industrial sensors, RTD and thermocouple temperature acquisition, weigh scales and load-cell signal conditioning, portable medical monitoring, smart sensor hubs, and battery-powered IoT edge nodes. When designing with this device, allocate at least 100 nF of ceramic decoupling on AVDD and DVDD within 2 mm of the supply pins, and guard-ring the analog inputs on the top layer to minimize leakage from digital switching. Calibration cycles every 100 ms are recommended for absolute-accuracy applications.

MAX11321ATJ+T

MAX11321ATJ+T - 12-Bit 1Msps SAR ADC, 16-Ch, TQFN-32 | Maxim

The Maxim Integrated (now Analog Devices) MAX11321ATJ+T is a 12-bit, 1Msps successive-approximation (SAR) analog-to-digital converter with 16 analog input channels and an external reference, housed in a 32-pin TQFN-EP (5x5 mm) package. According to the manufacturer datasheet, the device is part of the MAX11321-MAX11328 family of pin-compatible 12-/10-bit, 4-/8-/16-channel ADCs with 1Msps sampling, 1MHz full linear bandwidth, and serial SPI/QSPI/MICROWIRE-compatible output. The "+T" suffix denotes tape-and-reel packaging, while the "ATJ" suffix designates the 32-pin TQFN with exposed pad. A SAR (Successive Approximation Register) ADC is a type of analog-to-digital converter that performs a binary search through an internal DAC to determine the digital output code, one bit per conversion clock. SAR ADCs offer deterministic latency, low power consumption, and excellent DC accuracy, making them the architecture of choice for multiplexed data-acquisition systems, industrial sensor interfaces, and motor-control feedback loops where fast channel switching and precise single-shot conversions are required. Key features include a 1Msps throughput, 12-bit resolution with no missing codes, an internal 4.096V reference (or external reference option), a low-noise input signal conditioner in front of the analog multiplexer, and a wide analog input range of 0V to VREF. The MAX11321ATJ+T achieves >70dB SINAD and ±1 LSB INL/DNL at the rated throughput. The serial interface operates with clock frequencies up to ~24MHz and supports daisy-chaining of multiple ADCs. Architecturally, the MAX11321ATJ+T integrates an input-bandwidth-limiting pre-amplifier per channel, a high-impedance input multiplexer, a track-and-hold, a charge-redistribution SAR core, and a precision reference buffer. The post-mux signal-conditioning access pins let designers insert external filters or gain stages between the multiplexer and the ADC core, which is unusual in this class of converter and greatly simplifies multi-channel signal chains. Typical applications include 4-20mA industrial sensor acquisition, motor-drive phase-current sensing, multi-zone temperature monitoring, PLC analog input modules, and optical module monitoring. Designers also use this ADC in medical instrumentation front-ends and battery-management systems where high channel count and small PCB footprint are mandatory. When designing with this ADC, note the 32-pin TQFN package has an exposed thermal pad that MUST be soldered to the PCB ground plane for proper operation and thermal dissipation. The input multiplexer requires a settling time of about 200ns after each channel switch for full 12-bit accuracy, so engineers should insert a short software delay before triggering each conversion. The external reference input has a high impedance of about 25kohm, so a low-noise reference IC and a 10uF/0.1uF bypass are strongly recommended.

The Analog Devices (formerly Maxim Integrated) MAX11324ATJ+T is a 10-bit, 1Msps, 8-channel successive-approximation-register (SAR) analog-to-digital converter housed in a 32-pin TQFN (5x5 mm) package with exposed pad. Operating from a single 2.35V to 3.6V analog supply, it delivers up to 1Msps throughput while consuming only 5.6 mW at full speed, and includes an external reference input, 1MHz full-linear-bandwidth input mux, and a SPI/QSPI/MICROWIRE-compatible serial interface. An SAR ADC is a successive-approximation-register analog-to-digital converter that performs a binary search against a reference voltage to resolve each conversion in N clock cycles, where N is the resolution in bits. SAR ADCs offer deterministic latency, no pipeline delay, and excellent dynamic performance at moderate sample rates, occupying the engineering niche between precision slow-sampling delta-sigma ADCs and high-speed pipeline ADCs. They are widely used in industrial process control, motor control, and multi-channel data-acquisition systems where low-latency deterministic sampling of multiple analog signals is required. The MAX11324 belongs to the broader category hierarchy: SAR ADC -> data converter -> ADC -> signal chain IC -> mixed-signal semiconductor. Key features of the MAX11324ATJ+T include a 10-bit resolution (10-bit accuracy grade in the MAX11321-MAX11328 family), 1Msps maximum sample rate, 8 single-ended analog input channels, an integrated 8-to-1 input multiplexer with post-mux external signal-conditioning access, 1MHz full-linear-bandwidth track-and-hold, single 2.35V to 3.6V analog supply, an external reference input (REF) for design-driven full-scale range, an SPI/QSPI/MICROWIRE serial interface, low 5.6 mW power consumption at 1Msps, and an automatic channel-scan mode with internal averaging. The post-mux access to each analog input is a distinguishing feature that allows per-channel external amplifiers, filters, or attenuation networks to be inserted without disturbing the mux or track-and-hold. The MAX11324ATJ+T uses a charge-redistribution DAC architecture with internal capacitors and an external reference, achieving INL of ±1 LSB (max), SNR of 61 dB (typ at 1Msps), and SINAD of 60 dB. The TQFN-32 package with exposed thermal pad (EP) provides a thermal resistance (theta_JA) suitable for operation across the -40C to +125C automotive temperature range. The device supports 0 to n x VREF input ranges when used with the internal PGA in adjacent family members, but here operates in single-ended unipolar mode against the external reference. Typical applications include industrial process-control analog input modules, multi-channel sensor data acquisition, motor-control current/voltage monitoring, PLC analog input cards, battery-management telemetry, programmable logic controller (PLC) front-ends, and automotive sensor-cluster digitizers. The 8-channel single-ended input count, 1Msps sample rate, and small TQFN-32 footprint make it ideal for space-constrained multi-channel designs. A key design consideration is decoupling: place a 10uF bulk plus 0.1uF ceramic bypass close to AVDD and DVDD pins, keep the analog and digital ground planes joined at a single point, and route the REF bypass (4.7uF) directly to the EP ground. Use short, symmetrical traces on the analog inputs to minimize channel-to-channel crosstalk.

The integrated mux eliminates the need for an external analog switch and supports burst-mode sequencing for multi-channel scans. The MAX11327 uses Maxim's charge-distribution capacitive DAC architecture with an on-chip track-and-hold. The integrated reference, mux, and sequencer simplify system BOM, while the SPI-compatible serial interface supports daisy-chaining for applications that require more than eight channels. The 32-pin TQFN package's exposed thermal pad (EP) provides a low thermal-resistance path for continuous 1Msps operation across all eight channels. Typical applications include industrial process-control analog input modules, motor-control current sensing, optical-module monitoring, rack-mounted server telemetry, and automotive sensor interfaces where the -40C to +125C grade is required. The wide input range supports both voltage-output and current-loop transducer interfaces. When designing with this ADC, bypass VAVDD with a 10 uF ceramic capacitor placed within 5 mm of the EP, and provide a low-impedance AGND return from each analog input trace. Use SPI SCLK <= 50 MHz and gate SHDN low for <1 uA standby - the reference stays biased so subsequent conversions remain within specification.

MAX11332ATJ+T - 3Msps 12-Bit 16-Ch SAR ADC | Analog Devices

The Analog Devices MAX11332ATJ+T is a 3 Msps, 12-bit, 16-channel successive approximation register (SAR) analog-to-digital converter (ADC) with external reference and 500 kHz full-linear-bandwidth, housed in a 32-pin TQFN-EP (5x5 mm) package. It accepts 8 or 16 single-ended analog inputs through an integrated analog multiplexer and provides a serial SPI/QSPI/MICROWIRE-compatible digital interface for compact data acquisition designs. A SAR ADC is a type of analog-to-digital converter that performs conversion by binary-searching against a precision DAC and a comparator in a single clock cycle per bit. Within the broader data converter hierarchy, SAR ADCs sit between flash converters (fastest, lowest resolution) and delta-sigma ADCs (slowest, highest resolution). The MAX11332's 12-bit resolution with 3 Msps throughput makes it ideal for multiplexed multi-channel systems where fast acquisition and deterministic latency matter more than absolute noise floor. The post-mux signal conditioning access allows external amplifiers, filters, or sensor biasing between the analog input pins and the internal sample-and-hold. Key features include 3 Msps maximum sampling rate, 12-bit no-missing-codes resolution, 16 analog input channels (selectable 8 or 16 via configuration), an external reference voltage input for measurement flexibility, low power consumption (approximately 5.5 mW at 3 Msps), 500 kHz full-linear bandwidth, and a high-speed SPI-compatible serial interface operating up to 50 MHz. The TQFN-EP package provides a thermal pad that reduces junction-to-ambient thermal resistance to approximately 32 C/W. Architecture-wise, the device integrates an input multiplexer, sample-and-hold amplifier, SAR conversion core, reference buffer, and serial output logic on a single die. The external reference allows the user to optimize the ADC's input range to match sensor signals (e.g., 2.5V, 4.096V), which improves quantization noise utilization compared to a fixed 5V input range. Typical applications include multi-channel data acquisition systems, industrial process control and sensor monitoring, patient monitoring and medical instrumentation, programmable logic controllers (PLCs), and battery-powered portable instrumentation. The combination of 16 channels in a compact TQFN footprint replaces up to four dual-channel ADCs, saving board space. When designing with the MAX11332ATJ+T, ensure the external reference source is low-noise and adequately bypassed; a noisy reference directly multiplies into ADC output. Place a 0.1 uF ceramic decoupling capacitor close to each supply pin, and follow the PCB layout guidelines in the datasheet to preserve full 500 kHz input bandwidth.

The MAX11336 belongs to the Maxim Integrated SAR ADC product family and is part of a broader category: data converter -> ADC -> SAR ADC -> multi-channel low-power SAR ADC. Compared with delta-sigma converters, SAR parts deliver deterministic latency, which makes them well suited to multiplexed multi-channel data-acquisition loops. Key features include 500 ksps throughput on a single +3.3 V supply, low power consumption of approximately 5.4 mW at full speed, hardware- or software-configurable analog input ranges, and 16 analog input channels that can be configured for 4-, 8-, or 16-channel single-ended or pseudo-differential operation. The integrated post-mux signal-conditioning access lets designers insert external filters or buffers between the multiplexer output and the ADC input - a feature rarely found in integrated multi-channel SARs. The MAX11336's CMOS SAR architecture combines an input track-and-hold with an internal reference capacitor DAC and a precision comparator. Its 500 ksps full-linear-bandwidth and external-reference architecture allow the noise floor and absolute accuracy to be tuned by the reference choice. The serial-interface controller supports SPI Mode 0 and Mode 3 with QSPI- and MICROWIRE-compatible timing modes. Power dissipation scales linearly with sample rate because there is no continuous internal conversion loop, simplifying thermal budgeting at lower throughputs. Typical applications include industrial process control and PLC analog input modules, automotive sensor interfaces (battery management, current shunt monitoring, and HVAC controls), portable and battery-powered instrumentation, optical-module monitoring, and multi-loop data-acquisition systems. The 32-TQFN (5x5) package makes the part attractive for compact PCB layouts with strict height restrictions, such as handheld test equipment and modular IO cards. When designing with this device, place the reference decoupling capacitor and the input RC network as close as possible to the analog pins, and route the analog and digital grounds as separate nets joined at a single point under the exposed pad. Because the part is specified for the automotive -40 to +125 °C range, derating of input bandwidth and reference settling time at high temperature should be validated against the datasheet AC Electrical Characteristics table.

Key features include an integrated 4 or 8 input multiplexer, dedicated track-and-hold amplifier with 1:1 MUX:S&H:ADC ratio, SPI / DSP-compatible digital interface, and access to the post-mux analog front end for external signal conditioning such as programmable gain or filtering. The wide input range spans the analog supply rails, and the reference voltage is supplied externally to allow full-scale input scaling to match sensor or signal levels. Typical applications include industrial process control loops, multichannel data acquisition systems, automotive sensor monitoring, and embedded instrumentation front ends. The deterministic conversion latency also makes the part well suited to closed-loop control systems where predictable timing is required. When designing the input chain, place an RC anti-aliasing filter on each channel as close to the input pin as possible, and bypass the analog and digital supplies with 100 nF plus 10 uF ceramic capacitors. Drive the inputs through a low-impedance buffer if the source impedance exceeds 1 kohm to avoid conversion errors caused by incomplete settling of the internal S&H.

The analog input accepts a true bipolar ±12 V or 0 to +12 V range thanks to an internal input scaling/level-shift network, while a unipolar 0 to +4.096 V input can also be applied directly. The device draws 7.5 mA during conversion and drops to a few microamps in shutdown, supporting low-duty-cycle multiplexing strategies. The MAX1133 is built on a CMOS SAR core with an integrated bandgap reference, calibration logic, and a high-impedance CMOS serial-output port. The 20-pin SSOP package offers a small footprint while keeping analog and digital grounds separated to reduce coupling noise from the serial interface into the analog input.

Typical applications include industrial process control, multi-channel data-acquisition cards, medical instrumentation, weigh scales, and loop-powered 4-20 mA sensor transmitters. When designing with the MAX1133BEAP, decouple AVDD and DVDD separately with 0.1 µF ceramic capacitors placed close to the pins, and provide a 10 µF bulk capacitor on AVDD. Route the analog input traces as guard-traced microstrip away from the serial clock and digital outputs, and place a small RC filter (typically 100 Ω and 10 nF) at AIN-ADC to limit out-of-band noise. Because the MAX1133 uses an internal reference, allow a 10 ms settling window after power-up before initiating conversions.

MAX1134BCAP+

MAX1134BCAP+ - 16-Bit 150ksps ADC, 3.3V, SSOP-20 | Maxim

The Maxim Integrated (Analog Devices) MAX1134BCAP+ is a 16-bit, 150 ksps successive-approximation analog-to-digital converter (SAR ADC) with a single 3.3V supply input, housed in a 20-pin SSOP package. According to distributor listings, the part provides a 1-channel single-ended input, SPI/QSPI/MICROWIRE-compatible serial interface, integrated input scaling network, internal track/hold, and on-chip clock. The BiCMOS architecture achieves 150 ksps throughput at low power consumption suitable for portable and industrial data-acquisition systems. A SAR ADC is a successive-approximation-register analog-to-digital converter: it converts an analog input voltage into a digital code by performing one bit at a time using a comparator and a digital-to-analog converter (DAC) in a binary-search loop. In the broader component taxonomy, a SAR ADC sits under analog-to-digital converter -> data converter -> mixed-signal IC -> semiconductor. SAR ADCs are valued for deterministic latency, no-pipeline-delay behavior, and high DC accuracy, which makes them preferred over delta-sigma or pipeline ADCs in multiplexed channel-sampling and motor-control applications. The MAX1134BCAP+ integrates a track/hold amplifier, input scaling network, and clock generator, which eliminates the need for external components and reduces board area. The 150 ksps sampling rate combined with 16-bit resolution provides 91.3 dB theoretical dynamic range. The single 3.3V supply operation simplifies power-tree design in 3.3V-only systems, while the wide digital-interface compatibility (SPI, QSPI, MICROWIRE) allows direct connection to most microcontrollers and DSPs without glue logic. The MAX1134BCAP+ shares pinout and package with the MAX1135 family members, allowing designers to scale resolution (12/14/16-bit) and sample rate (150/200 ksps) using the same PCB footprint. The 20-pin SSOP (CAP suffix) is a 5.30 mm JEDEC standard body, while the 20-pin SSOP (EAP suffix) is a 7.20 mm JEDEC standard body - these are NOT drop-in compatible. Typical applications include portable instrumentation, data loggers, process-control front ends, pen-digitizer digitizers, and battery-powered measurement equipment. The wide operating temperature range suits industrial environments. When designing with this device, place the 0.1 uF decoupling capacitor within 3 mm of the AVDD pin and keep analog/digital ground returns separated until they join at the ADC. Source impedance should remain below the datasheet limit to maintain acquisition time.

It integrates an internal track/hold, voltage reference, clock, and an I2C-compatible 2-wire serial interface supporting 400 kHz Fast Mode and 1.7 MHz High-Speed Mode operation. A SAR ADC is a successive-approximation-register analog-to-digital converter that uses a binary search algorithm with an internal DAC and comparator to convert analog input voltages into digital codes within a single conversion cycle per bit. Within the broader hierarchy, the MAX1138KEEE+ is a multi-channel data converter -> ADC analog-to-digital converter -> data-acquisition IC -> mixed-signal semiconductor. Key differentiating features include 12 single-ended analog input channels (vs. 4 channels on the MAX1136), an internal 2.5V reference, software-configurable unipolar/bipolar inputs, and an automatic channel-scanning state machine that cycles through selected channels sequentially. The part also integrates an internal oscillator and programmable acquisition time, eliminating the need for an external clock source. Typical applications include portable data logging, patient monitoring, system supervision in embedded control, thermocouple/thermistor front-end digitisation, and battery-powered instrumentation where the small QSOP-16 footprint and low supply current (typically 200 µA at the lowest throughput) are decisive. The internal reference and track/hold simplify BOM cost and layout complexity. When designing with this device, ensure the SCL/SDA pull-ups follow I2C bus specifications (typically 4.7 kΩ at 3.3V for Fast Mode) and that the AIN inputs respect the absolute-maximum input range to avoid latch-up. For best noise performance, place 0.1 µF bypass capacitors directly at VDD and use the internal reference rather than an external source.

Key features include 12 analog input channels (11 single-ended plus differential), an internal 2.5V reference, software-configurable unipolar/bipolar input ranges, an external reference option for ratiometric measurements, and a hardware/software shutdown mode that drops supply current to 1 microA. The 16-pin SSOP (K package) measures approximately 4.9 mm x 3.9 mm with a 0.635 mm pitch, suiting compact designs where board area is at a premium. The MAX1138 integrates track-and-hold, clock, and reference on-chip, eliminating external components and reducing BOM cost. Its I2C interface supports up to eight devices on a single bus via two address pins, simplifying multi-ADC systems. The wide 4.5V-5.5V supply range makes it directly compatible with 5V microcontrollers and legacy industrial rails. Typical applications include industrial sensor monitoring (temperature, pressure, strain gauge bridges), portable instrumentation, patient monitoring devices, data-acquisition systems, and battery-powered measurement equipment. The 12-channel count is well suited to multi-zone HVAC controllers, PLC analog modules, and embedded control boards where many sensors share one ADC. When designing with the MAX1138KEEE+T, ensure the I2C pull-up resistors match the bus speed - 4.7k for 400 kHz, 1k for 1.7 MHz High-Speed Mode. Add 0.1uF decoupling close to VDD and bypass the reference pin per the manufacturer datasheet. For highest absolute accuracy, use an external low-noise reference instead of the internal 2.5V bandgap.

MAX1139KEEE+

MAX1139KEEE+ - 10-Bit 12-Ch SAR ADC, I2C, 16-QSOP | Maxim Integrated

The Maxim Integrated (Analog Devices) MAX1139KEEE+ is a low-power, 10-bit, 12-channel (6 differential), successive-approximation analog-to-digital converter (SAR ADC) with an I2C-compatible 2-wire serial interface, housed in a 16-pin QSOP package. It operates from a single 2.7V to 3.6V or 4.5V to 5.5V supply, includes an internal track/hold, internal 4.096V reference (K-grade), internal clock, and accepts analog inputs from 0 to VAVDD. The K-suffix variant indicates the higher 4.5V-5.5V supply option with 12 input channels. An SAR (Successive Approximation Register) ADC is a type of analog-to-digital converter that uses a binary search algorithm through an internal capacitive DAC to convert an analog input to a digital code in N conversion cycles for N bits of resolution. SAR ADCs are prized for low power consumption, deterministic latency, and excellent DC accuracy, making them a cornerstone architecture for multi-channel data-acquisition systems, sensor monitoring, and industrial control loops where a single ADC must sequentially scan many analog signals. Key features of the MAX1139KEEE+ include 117ksps maximum sampling rate (K-grade), I2C-compatible 2-wire serial interface (Fast Mode 400kHz), six analog input channels configurable as 6 single-ended or 3 differential inputs (12 total input pins), internal 4.096V voltage reference (K/M variants), low 670µA supply current at maximum sampling rate, and 1µA power-down current. The wide supply range lets the same part serve both 3.3V and 5V digital systems without level shifters. The architecture combines an input track/hold, a 10-bit charge-redistribution DAC, a comparator, and an internal 4.096V bandgap reference. The I2C address is factory-set (with 16 possible addresses) and the device supports both Standard Mode (100kHz) and Fast Mode (400kHz). The QSOP-16 package has a thermal resistance of approximately 150°C/W and is specified for the -40°C to +85°C extended industrial temperature range. Typical applications include portable data logging, patient monitoring, battery-powered instrumentation, HVAC sensor arrays, and process control. The 12 single-ended / 6 differential input channels make the part especially attractive for scanning multi-sensor arrays (temperature, pressure, flow) with a single ADC. The internal reference eliminates external reference components, reducing BOM and PCB area. When designing with this ADC, place 0.1µF bypass capacitors close to VDD and VAVDD pins, and ensure the I2C pull-ups (typically 2.2kΩ-10kΩ) are sized for the bus capacitance. The analog input impedance is high (multiplexer-based) so source-impedance effects are minimal, but a low-impedance input driver is still recommended for best AC performance.

MAX1139MEEE+

MAX1139MEEE+ - 10-Bit 12-Ch I2C SAR ADC | Analog Devices

The Analog Devices (formerly Maxim Integrated) MAX1139MEEE+ is a low-power, 10-bit, 12-channel (6 single-ended/6 differential) successive-approximation analog-to-digital converter with an internal track/hold, internal voltage reference, internal clock, and an I2C-compatible 2-wire serial interface, housed in a 16-pin QSOP package. An SAR (successive-approximation register) ADC is a precision data-converter architecture that performs a binary search across an internal capacitive DAC to produce a digital output in N conversion cycles for N bits of resolution. SAR ADCs occupy the middle ground between flash converters (fastest, lowest resolution) and sigma-delta converters (highest resolution, slower), combining moderate speed (tens to hundreds of ksps), deterministic latency, and low power consumption, making them the workhorse for multi-channel data acquisition, sensor interfacing, and industrial control. The MAX1139MEEE+ operates from a single 2.7V to 3.6V supply, draws only 670 µA at the maximum 94.4 ksps sampling rate, and supports an I2C-compatible 2-wire serial interface. Key features include 10-bit resolution, software-configurable unipolar/bipolar and single-ended/differential inputs, an internal 2.048V reference, and a hardware/software shutdown mode that reduces supply current to under 1 µA for battery-powered applications. The 16-QSOP package is pin-similar to the rest of the MAX1136-MAX1139 family, allowing PCB reuse across 3V/5V and 4/12-channel variants. The internal 2.048V reference and track/hold eliminate external analog components, simplifying BOM and saving board area. The 94.4 ksps throughput and I2C bus up to 400 kHz (Fast-Mode) suit the device for monitoring slow-to-medium-speed signals such as temperature, pressure, and battery cell voltages in portable, industrial, and medical instruments. Typical applications include portable data loggers, battery-pack monitoring, industrial process control loops, HVAC sensor interfaces, and patient-monitoring front ends where multiple low-bandwidth analog channels must be digitized with deterministic latency and minimal firmware overhead. When designing with this part, add 0.1 µF bypass capacitors close to AVDD and DVDD and respect the 400 kHz I2C bus-capacitance budget. Because the inputs are software-configurable, a single MAX1139MEEE+ can replace several discrete ADCs and an analog mux, reducing both footprint and firmware complexity.

MAX1139MEEE+T

MAX1139MEEE+T - 12-Ch 10-Bit SAR ADC I2C | Maxim Integrated

The Analog Devices (formerly Maxim Integrated) MAX1139MEEE+T is a 10-bit, low-power, multi-channel successive-approximation analog-to-digital converter (SAR ADC) with 6/12 analog input channels and an I2C-compatible 2-wire serial interface, housed in a 16-pin QSOP package. It operates from a single 2.7V to 3.6V or 4.5V to 5.5V supply, integrates an internal track/hold, an internal 2.048V voltage reference (MAX1137/MAX1139 family), an internal oscillator, and an I2C serial interface in a single IC, drawing a low supply current suitable for battery-powered and portable systems. A SAR ADC (Successive Approximation Register Analog-to-Digital Converter) is a type of data converter that uses a binary search algorithm against an internal precision DAC to convert an analog input voltage into a digital code, one bit per clock cycle. SAR ADCs occupy the middle ground between slow but precise integrating/delta-sigma ADCs and fast but power-hungry flash ADCs: they offer 8-18 bit resolution, moderate sampling rates (up to several MSPS), zero-latency single-shot conversion, and low power consumption. Within the broader data-converter hierarchy, the MAX1139 belongs to: SAR ADC -> ADC -> Data Converter -> Mixed-Signal IC -> Semiconductor. Key specifications include 10-bit resolution, 6 or 12 single-ended input channels (software-configurable via the setup byte), an internal 2.048V reference, an I2C-compatible 2-wire serial interface with up to 400 kHz fast-mode support, an integrated track/hold amplifier, and an internal clock. The device operates over the -40C to +85C extended industrial temperature range. The MAX1136-MAX1139 family offers pin-compatible 4-channel MAX1136/MAX1137 (8-pin uMAX) and 12-channel MAX1138/MAX1139 (16-pin QSOP) variants sharing the same register set and serial protocol, enabling drop-in migration between channel counts and reference voltages (2.048V vs 4.096V) on the same I2C bus. Typical applications include portable and battery-powered instrumentation, system monitoring in networking and server hardware, multi-cell battery monitoring, power-supply supervision, sensor signal conditioning, and consumer-electronics front panels. The internal reference and small QSOP footprint minimize external component count, and the I2C interface allows up to four devices on a single 2-wire bus by selecting different slave addresses via external address pins. When designing with this part, observe I2C bus pull-up sizing: with four MAX1139 devices on the bus, total sink current is 4 x 3 mA = 12 mA, which limits pull-up resistor values to keep rise time within the 400 kHz fast-mode budget. The internal reference eliminates an external component but limits absolute accuracy to the trimmed internal value - verify against system calibration requirements before committing to the internal reference option.

MAX113CAG+

MAX113CAG+ 8-Bit 4-Channel ADC | Analog Devices

Analog Devices MAX113CAG+ is an 8-bit, 4-channel analog-to-digital converter operating from a single +3 V supply and achieving a 400 ksps conversion rate in a 24-pin SSOP package. The converter uses a half-flash architecture to deliver a 1.8 µs conversion time, while its microprocessor-compatible parallel interface supports efficient connection to embedded control systems. The device also includes a power-down mode with 1 µA current consumption, making it suitable for portable and power-conscious industrial measurement systems. An ADC is a semiconductor device that converts an analog input voltage into a digital code for processing, storage, or control. The MAX113CAG+ belongs to the ADC and DAC hierarchy within integrated circuits and combines a four-channel multiplexer, sample-and-hold circuitry, an 8-bit flash converter, and a parallel digital interface in one package. Its four single-ended inputs allow one controller to monitor multiple analog sources without requiring a separate converter for every channel. Key features include 8-bit resolution, four analog input channels, a +3 V single-supply operating requirement, a 400 ksps conversion rate, and a 1.8 µs conversion time. The half-flash conversion architecture supports throughput-oriented acquisition while preserving the simple parallel interface commonly used by microprocessors and programmable logic controllers. A dedicated power-down function reduces supply current to 1 µA when intermittent measurements are sufficient. The MAX113/MAX117 family is designed for microprocessor-compatible data acquisition. The MAX113CAG+ provides four channels in the 24-pin SSOP package, distinguishing it from eight-channel family members. Its architecture is appropriate when several slowly changing or periodically sampled analog signals must be digitized into an 8-bit value. Because the converter uses a parallel data interface, the host processor must connect its data bus and control signals according to the manufacturer pin-description table. Typical applications include industrial process monitoring, factory automation, battery-powered instrumentation, data loggers, embedded environmental measurement, and general-purpose control systems. The 400 ksps rate is useful when the controller needs to scan all four inputs quickly, while the 8-bit resolution is appropriate for position, level, threshold, and status monitoring rather than laboratory-grade instrumentation requiring higher resolution. Designers should account for input-range selection, signal conditioning, acquisition timing, and reference accuracy when assigning the four analog channels. The +3 V supply and single-ended inputs simplify portable measurement systems, while the 24-pin SSOP footprint requires careful routing of parallel bus signals. Use the manufacturer pin-description table when assigning tracks and confirm the power-down polarity before integrating the control logic. This product page organizes the MAX113CAG+ specifications, practical application guidance, lifecycle information, and verified same-package alternatives. It also highlights design constraints that are easy to overlook when selecting a multi-channel ADC, including interface timing, supply architecture, channel multiplexing, and power management.

MAX113CAG+TG068

MAX113CAG+TG068 - 8-Bit 400ksps 4-Ch ADC | Maxim

The Maxim MAX113CAG+TG068 is a +3V, 4-channel, 8-bit analog-to-digital converter (ADC) with 1 microampere power-down mode, delivered in a 24-pin SSOP (CAG) package and shipped on tape-and-reel with the +TG068 suffix. The device uses a half-flash conversion architecture to achieve a 1.8 microsecond conversion time, equivalent to a 400 ksps throughput, with an external reference. It is part of the MAX113/MAX117 family - the MAX113 offers 4 analog input channels while the MAX117 doubles that to 8 channels - and is designed for direct connection to microprocessors with mode-selectable read/write timing. An 8-bit ADC (analog-to-digital converter) is a data-acquisition IC that converts continuous analog input voltages into discrete 8-bit digital codes with 256 quantization levels, providing 48 dB of theoretical dynamic range. In the system hierarchy, the MAX113 sits under Data Acquisition -> Converter -> ADC -> Mixed-Signal IC. Half-flash (also called sub-ranging flash) architectures use two 4-bit flash sections and one DAC per conversion step to halve the comparator count versus a full flash design - this reduces die area and power consumption while still reaching 400 ksps, the practical speed boundary for parallel-output ADCs of this generation. Key features include single +3V supply operation, four single-ended analog inputs with channel selection, a hardware power-down pin that drops quiescent current to 1 microampere between conversions, and microprocessor-compatible interface logic. The half-flash engine delivers 8 bits of resolution at 400 ksps, suitable for system-monitoring loops, transducer digitizers, and portable instrumentation front-ends where low power and small PCB area matter more than 12-16 bit precision. The half-flash core samples an input through two 4-bit flash stages back-to-back. The first stage determines the four most-significant bits and computes a 4-bit residue using an internal DAC; the second stage resolves the four least-significant bits from that residue. This two-step technique halves the comparator count from 255 to about 32, lowering both silicon cost and switching noise - the trade-off is one extra clock cycle of latency per conversion, which is invisible to most microcontrollers polling the parallel data bus. Typical applications include handheld multimeter digitizers, portable industrial sensor front-ends, battery-powered data loggers, panel-meter readouts, and microprocessor-based control boards where multiple analog transducer signals must be read sequentially. The 1 microampere power-down current is specifically valuable for battery-management and IoT-sensor designs that wake the ADC only on demand. When designing with this IC, place the 0.1 microfarad VDD bypass capacitor within 5 mm of the VDD pin and keep the analog input traces short and guarded to ground. The MODE pin selects the read/write bus protocol - tie it high for memory-mapped interface or low for I/O-mapped interface - so make this decision before laying out the microcontroller bus. Do not leave the reference input floating; use a low-impedance reference such as a MAX6129 or a buffered +2.5V source for specified accuracy. This page synthesizes distributor pricing, drop-in same-package alternatives, pin-by-pin comparison, and practical design notes not collected in the manufacturer datasheet, helping engineers pick a replacement or verify second-source options without rereading twenty years of Maxim product change notices.

The MAX113CNG+ combines four analog input channels, parallel microprocessor-compatible output, and an 8-bit resolution in one through-hole package. The half-flash conversion architecture provides a practical choice when a system needs moderate sampling speed and compact 8-bit measurement rather than higher-resolution SAR conversion. Its single 3 V supply also simplifies connection to contemporary 3.3 V digital systems. According to the available manufacturer-datasheet descriptions, the MAX113 and MAX117 family is designed for microprocessor-compatible data acquisition and includes power-down capability. The MAX113CNG+ specifically provides four input channels, while the related MAX117 provides eight channels. Engineers can use the MAX113CNG+ for industrial control, instrumentation, panel interfaces, and other systems where four analog quantities must be sampled with a parallel interface. Its 24-pin PDIP package is easy to prototype and inspect, although the through-hole format is larger than a modern surface-mount ADC package. The device's 8-bit resolution represents 256 quantization levels, making it appropriate for coarse measurement, thresholding, position indication, and supervisory control rather than precision laboratory conversion. Application timing should be based on the specified 400 ksps throughput and the manufacturer's bus-access requirements. Power sequencing and signal-source drive capability must be checked against the full datasheet before production use, because those detailed limits are not present in the supplied source excerpts.

Maxim Integrated MAX113EAG+ is an 8-bit, 4-channel, 400ksps flash analog-to-digital converter operating from a single +3V supply in a 24-pin SSOP package. It combines a 1.8µs conversion time, microprocessor-compatible interfacing, and a 1µA power-down mode for compact low-power measurement systems. An ADC is a data-conversion IC that converts an analog voltage into a digital code for processing, measurement, or control. The MAX113EAG+ belongs to the flash-converter ADC hierarchy, combining a 4-bit flash stage with a 4-bit successive-approximation stage to achieve 8-bit resolution. This architecture supports sampling-based acquisition in industrial control, sensor conditioning, panel interfaces, and embedded instrumentation. The principal operating characteristics are 8-bit resolution, 4 analog input channels, a 400ksps conversion rate, and operation from a single +3V supply. The 24-SSOP package is intended for surface-mount assembly. A 1.8µs conversion time supports rapid acquisition, while the 1µA power-down current reduces standby consumption in intermittently operating equipment. The converter is designed for microprocessor-compatible systems, allowing acquisition results to be transferred through a digital bus and then processed by a microcontroller or logic controller. Its flash conversion method avoids the longer conversion sequence associated with successive-approximation-only ADC architectures. Supply-noise sensitivity, input-source impedance, acquisition timing, and output-code accuracy must still be evaluated against the circuit requirements. Typical uses include four-channel sensor acquisition, industrial process monitoring, digital panel meters, battery-operated instruments, and embedded control systems. The four-channel architecture reduces the number of separate converters required when several slow or moderate-speed analog signals must be digitized, while the 400ksps rate allows successive readings to be captured rapidly. The principal design consideration is preserving signal integrity from each sensor to the analog inputs. Use short traces, suitable input filtering, and an analog ground strategy consistent with the manufacturer datasheet. Because the device operates from +3V, confirm that every input remains within its specified analog input range before applying externally generated voltages. This product page combines the device specifications, application guidance, pin-compatible alternatives, and design notes needed to qualify the MAX113EAG+ for a new PCB. It also provides a structured path for comparing the converter with other same-package ADC options before final schematic approval.

What is an 8-bit half-flash ADC? A half-flash ADC is a type of analog-to-digital converter that uses two parallel 4-bit flash stages plus a digital-to-analog converter (DAC) and subtractor to perform an 8-bit conversion in roughly two comparator bank cycles, achieving tens to hundreds of ns per stage. Positioned in the taxonomy: ADC > data converter > signal chain IC > semiconductor, the half-flash architecture is the same family used by the MAX113's companion MAX117 (8-channel variant) and is well suited for embedded microcontrollers, data loggers, and instrumentation front-ends where medium-speed, low-power conversion is required and 12-16 bit precision is not necessary. Key features include a parallel microprocessor interface, single-ended analog inputs with external reference, software-configurable unipolar/bipolar input range, and an analog input bandwidth suitable for audio-bandwidth signals. A hardware power-down pin reduces standby current to 1 µA typical, allowing the ADC to be duty-cycled in battery-powered applications. The 24-pin PDIP package provides easy insertion into through-hole prototypes and educational platforms. The MAX113ENG uses two stacked 4-bit flash ADC sub-blocks plus an internal 4-bit DAC, achieving a total throughput of 400 ksps at 1.8 µs per conversion. The internal track/hold keeps input bandwidth compatible with audio-range multiplexed sources, and the external reference voltage scales the full-scale input range independently of the supply, simplifying ratiometric measurements. Typical applications include portable data loggers, battery-powered instrumentation, digital panel meters, simple DSP front-ends, and embedded 8-bit MCU analog input modules where a true 12-bit ADC is overkill but a discrete CMOS comparator ladder is too slow. Because of its 24-pin DIP form factor and 3V supply, it is a popular choice for hobbyist and educational hardware. Designers should add 100 nF decoupling capacitors directly across the VDD and AGND pins and use the PWRDN pin to manage average supply current in duty-cycled systems. The external reference determines absolute accuracy, so a low-drift, low-noise reference such as the MAX6125 or MAX6190 is recommended for instrumentation-grade measurements.

MAX1142BCAP+

MAX1142BCAP+ - 14-Bit 200ksps ADC, +5V, 20-SSOP | Maxim Integrated

The Maxim Integrated MAX1142BCAP+ is a 14-bit, 200 ksps successive-approximation analog-to-digital converter (ADC) with a +5V single supply and an internal +4.096V reference, housed in a 20-pin SSOP package. The device features one single-ended analog input channel and a serial interface compatible with SPI/QSPI/MICROWIRE, eliminating the need for external logic. Its combination of an input scaling network, internal track/hold, on-chip clock, and integrated reference reduces total BOM cost and board area for compact data-acquisition designs. An ADC (analog-to-digital converter) is a semiconductor device that converts continuous analog signals into discrete digital codes for processing by microcontrollers, DSPs, or FPGAs. Successive-approximation-register (SAR) ADCs use a binary-search algorithm with an internal DAC to resolve N bits in N clock cycles, achieving an excellent balance of speed, resolution, and power consumption. Within the broader taxonomy, SAR ADCs sit between flash converters (fastest, lowest resolution) and sigma-delta ADCs (highest resolution, slowest), and they are a key sub-category of mixed-signal data converters used across industrial, instrumentation, and embedded systems. Key specifications of the MAX1142BCAP+ include 200 ksps sampling rate, 14-bit resolution (no missing codes), ±1 LSB INL (B-grade), an internal +4.096V reference, and 1 input channel. Power-supply requirements are +5V single-ended analog supply and +5V digital supply. The integrated +4.096V reference is convenient because 4.096V is exactly 1 mV per LSB, simplifying engineering-unit scaling. The wide input scaling network (via external resistor network) supports input ranges up to ±4A in current-sensing applications. The MAX1142BCAP+ uses a charge-redistribution DAC with a precision bandgap reference, achieving low noise and high DC accuracy. The serial interface uses SPI/QSPI/MICROWIRE protocols, allowing direct connection to most microcontrollers and DSPs. An external reference can override the internal +4.096V reference when higher accuracy or a different full-scale range is required. Typical applications include industrial process control and instrumentation, temperature and pressure monitoring with bridge sensors, current sensing in motor control, battery-powered data loggers, and patient monitoring. The wide input range makes it particularly attractive for ±4A current shunt monitoring and ±10V industrial signal conditioning. When designing with the MAX1142BCAP+, ensure adequate input scaling to match full-scale range, and provide proper decoupling at AVDD and DVDD pins. The internal reference requires a stable supply; for noisy environments, add a 0.1uF ceramic bypass capacitor adjacent to the REF pin to minimize reference-induced conversion noise. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on the manufacturer datasheet, providing a single reference for engineers evaluating or sourcing the MAX1142BCAP+.
