ADS574KPG4 - 12-Bit 40kS/s SAR ADC, 28-PDIP | Texas Instruments
The Texas Instruments ADS574KPG4 is a 12-bit successive-approximation-register (SAR) analog-to-digital converter with a single-ended analog input and parallel microprocessor-compatible digital interface, housed in a 28-pin PDIP (0.600 in / 15.24 mm) through-hole package. Per the TI datasheet, it integrates a precision reference, internal clock, and a full microprocessor interface, providing a complete sampling ADC in one IC. The G4 suffix denotes the RoHS-compliant (green) lead-free finish variant of the legacy ADS574K family. 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 (CDAC) to convert an analog input voltage to a 12-bit digital code. The SAR architecture occupies the middle ground between flash ADCs (fastest, highest power) and sigma-delta ADCs (highest resolution, lowest bandwidth) and is the dominant topology for 8-16 bit precision conversions up to a few MSPS. The ADS574KPG4 belongs to the precision-converter hierarchy: SAR ADC -> data converter -> ADC -> signal chain -> mixed-signal IC. Key features include 12-bit resolution, 40 kS/s maximum sampling rate, 25 microseconds maximum acquisition-plus-conversion time, single +5 V supply operation (with optional -15 V for bipolar input range), parallel 12-bit output bus, and 0-70 degrees C commercial operating temperature range. The device is a direct drop-in replacement for the older ADC574 in most new designs, offering internal sampling, lower CMOS power, and a simpler single-supply option. The converter uses an innovative low-power CMOS capacitor-array DAC (CDAC) architecture that eliminates the need for an external sample-and-hold in most DC and slowly-varying applications. This simplification, combined with the integrated reference and clock, lets designers add 12-bit data acquisition to microprocessor-based systems with a minimal external parts count, while keeping total power well below bipolar ADC574 implementations. Typical applications include industrial process-control front ends, multiplexed data-acquisition boards, microprocessor-based instrumentation, factory-automation input modules, and legacy 12-bit replacement designs that previously used the ADC574. The 28-PDIP package is convenient for through-hole prototyping, repair, and field-replacement of older systems where SMD parts cannot be retrofitted without a board re-spin. When designing with the ADS574KPG4, ensure the analog input stays within the specified common-mode range for the chosen unipolar/bipolar mode, decouple the supply pins with 0.1 microfarad and 10 microfarad capacitors placed close to the IC, and observe the 25 microsecond conversion-time budget when sequencing multiple channels through an external multiplexer. Note the parallel bus timing carefully when interfacing to modern microcontrollers, which may require logic-level translation. This page synthesizes current distributor pricing, drop-in replacement candidates, application guidance, and practical design notes not found in the manufacturer datasheet, helping engineers select and source the ADS574KPG4 efficiently for new and legacy designs.
ADS58C28IRGC25 - Dual 11-Bit 200MSPS ADC | Texas Instruments
The Texas Instruments ADS58C28IRGC25 is a dual-channel, 11-bit analog-to-digital converter (ADC) sampling up to 200 MSPS, housed in a 64-pin VQFN (RGC) package measuring 9x9 mm. The device uses innovative design techniques to achieve high dynamic performance while consuming extremely low power from a 1.8 V supply, making it well-suited for multi-carrier, wide-bandwidth communications. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous analog voltages into binary digital codes. High-speed pipeline ADCs such as the ADS58C28 use a switched-capacitor pipeline architecture, sampling the input on a track-and-hold stage and propagating the residue through successive low-resolution stages. In the system hierarchy the ADS58C28 sits as: pipeline ADC -> ADC -> data converter -> mixed-signal IC -> integrated circuit. It is a foundational building block for digitizing IF/RF signals in software-defined radio, base stations, and instrumentation. Key specifications include 200 MSPS maximum sample rate, 83 dBc SFDR, 72.5 dBFS SNR with 60 MHz bandwidth using TI's third-generation SNRBoost3G technology, 1.8 V analog/digital supply, and CMOS-compatible LVDS outputs. The SNRBoost3G feature supports wide-bandwidth multi-carrier reception by allowing digital post-processing to remove in-band spurs, dramatically improving effective dynamic range in dense carrier environments. Architecturally, the ADS58C28 uses a differential input buffer, a wide-bandwidth track-and-hold, a digital gain and offset correction loop, and dual parallel LVDS output buses. Per-channel digital decimation filters can be applied to relax anti-alias requirements and reduce out-of-band noise. The 64-pin VQFN package with exposed thermal pad enables compact PCB layouts suitable for mezzanine cards and densely populated base-station line cards. Typical applications include wireless infrastructure receivers (multi-standard 2G/3G/4G/5G base stations), software-defined radio (SDR) and wideband IF sampling, test and measurement instrumentation, radar and EW signal acquisition, and medical imaging front-ends. The dual-channel integration halves the PCB footprint versus two discrete ADCs while preserving channel-to-channel matching. A key design consideration is that the SNRBoost3G mode requires an external FPGA or DSP to perform digital spur cancellation. Designers must allocate LVDS output lanes (DDR) and provide matched-length PCB routing. The 1.8 V supply requires low-noise LDO regulators (e.g., TPS7A4701 family) for the analog AVDD rail to avoid coupling switching noise into the ADC.

Key features of the ADS6122IRHBR include 12-bit resolution at up to 65 MSPS, selectable CMOS or DDR LVDS digital interface, low power consumption suitable for portable and densely-populated boards, an internal sample-and-hold, and a 3.3 V analog supply. The pipelined core delivers low latency and excellent spurious-free dynamic range (SFDR) for communications, imaging, and instrumentation front ends. Internal reference and high-impedance analog inputs simplify external BOM. Architecturally, the ADS6122IRHBR combines a high-bandwidth differential input sample-and-hold, a multi-stage switched-capacitor pipeline, and an output stage that can be configured for either single-data-rate CMOS or double-data-rate LVDS. The DDR LVDS mode is particularly valuable for interfacing with high-speed FPGAs and ASICs where board trace count must be minimized at high sampling rates. Typical applications include wireless communication baseband IF sampling, medical imaging front ends, handheld oscilloscopes, radar signal processing, and industrial test and measurement equipment. The 65 MSPS sample rate is well-suited for IF digitization in narrow-band receivers and for ultrasound beamforming preprocessing. When designing with this device, place input RC anti-aliasing networks close to the analog input pins, provide a clean low-noise 3.3V analog rail separate from the digital 3.3V domain, and tie the LVDS/CMOS mode select pin correctly during PCB layout to avoid mode contention. Decouple the supply pins with 0.1 uF and 10 uF capacitors.

An analog-to-digital converter (ADC) is an integrated circuit that converts continuous-time analog signals into discrete digital codes for processing by microcontrollers, FPGAs, or DSPs. Pipeline ADCs like the ADS6123 achieve high sample rates (tens to hundreds of MSPS) by distributing conversion work across multiple low-resolution stages, achieving an excellent trade-off between speed, resolution (typically 8-14 bits), and power consumption. The category hierarchy is ADC -> data converter -> data acquisition IC -> signal chain -> mixed-signal semiconductor.

The output interface is software-configurable: DDR LVDS for low-noise high-speed board-level transfer at full 80 MSPS, or parallel CMOS for direct low-cost FPGA connections. Input bandwidth is approximately 500 MHz, and spurious-free dynamic range (SFDR) typically exceeds 75 dBc at 70 MHz input. Typical applications for the ADS6123IRHB25 include multi-carrier telecom receivers, low-power portable test and measurement instruments, medical imaging front-ends, and baseband processing blocks in wireless infrastructure. The wide analog supply range (3.0 V to 3.6 V) and digital I/O supply range (1.65 V to 3.6 V) ease integration with 3.3 V and 1.8 V FPGA/ASIC logic, removing the need for level translators and reducing BOM cost. When designing with this ADC, pay close attention to analog input common-mode voltage, clock jitter (below 200 fs RMS is recommended to avoid degrading SNR), and decoupling on the analog supply pins. The exposed thermal pad must be soldered to a sufficient copper pour to maintain junction temperature. Internal reference mode simplifies BOM but external reference mode allows gain calibration across channels.
