Texas Instruments ADS62P25IRGCT

Overview

ADS62P25IRGCT from Texas Instruments is a dual-channel, 12-bit analog-to-digital converter (ADC) with 125 MSPS maximum sampling rate, DDR LVDS and parallel CMOS output interfaces, and integrated digital processing block including decimation (×2/4/8), 24-tap programmable filters, and fine gain correction (0.05 dB steps). It targets high-performance signal acquisition in radar systems and medical imaging equipment where wide analog input bandwidth (450 MHz) and low crosstalk (95 dB) are critical.

For engineers reviewing the ADS62P25IRGCT datasheet, ADS62P25IRGCT pinout, ADS62P25IRGCT application, or ADS62P25IRGCT equivalent, this page delivers verified specifications-including SFDR (84 dBc at 190 MHz, 3.5 dB gain), SINAD (69.5 dBFS), analog power (799 mW), 64-QFN package, and industrial temperature range (–40°C to 85°C)-to support precise signal chain design, layout validation, and drop-in evaluation against performance-critical ADC requirements.

Technical Context

The ADS62P25IRGCT implements a dual-sampling architecture with independent channel A and B paths, each featuring internal sample-and-hold, low-jitter clock buffer, and configurable coarse (0 dB / 3.5 dB) and fine (±6 dB in 0.05 dB steps) gain for SNR/SFDR trade-off optimization. Its digital processing block operates post-conversion and supports real-time offset correction, decimation, and programmable FIR filtering-bypassable by default.

It supports flexible clocking with sine, LVPECL, LVDS, or LVCMOS inputs (400 mVPP minimum amplitude), includes a clock duty cycle stabilizer, and offers dual output modes: DDR LVDS (with 225–350 mV differential swing) or parallel CMOS (1.8 V to 3.6 V DRVDD). Internal reference (1 V–2 V) eliminates external reference pins, though external reference mode remains supported via VCM pin.

Key Specifications

Pinout & Package

FAQ

What is the maximum sampling rate supported by the ADS62P25IRGCT?

The ADS62P25IRGCT supports a maximum sampling rate of 125 MSPS, as specified in the TI SLAS576C datasheet. This rate is achievable across the full industrial temperature range (–40°C to 85°C) with AVDD = 3.3 V and proper clock signal integrity. At this rate, the device maintains 69.5 dBFS SINAD and 84 dBc SFDR at 190 MHz input with 3.5 dB coarse gain, making ADS62P25IRGCT suitable for wideband signal acquisition in radar and communications infrastructure.

Does the ADS62P25IRGCT include an internal voltage reference?

Yes, the ADS62P25IRGCT integrates an internal reference with VREFT = 2 V and VREFB = 1 V, eliminating the need for external reference components and associated decoupling capacitors. The device also supports external reference mode via the VCM pin (1.45–1.55 V), allowing system-level calibration or tighter voltage tolerance requirements. Both modes are selectable using the SCLK pin voltage level per Table 4 in the ADS62P25IRGCT datasheet.

What output interface options does the ADS62P25IRGCT support?

The ADS62P25IRGCT supports two parallel output interfaces: DDR LVDS and CMOS. DDR LVDS operates with DRVDD = 3.0–3.6 V and delivers 225–350 mV differential swing into 100 Ω loads; CMOS supports DRVDD = 1.8–3.6 V with configurable drive strength. Interface selection is controlled via the SEN pin voltage in parallel mode or through serial register programming, enabling flexible integration with FPGAs, ASICs, or DSPs without hardware changes.

Can the ADS62P25IRGCT perform on-chip digital filtering?

Yes, the ADS62P25IRGCT includes a configurable digital processing block with built-in and custom programmable 24-tap FIR filters supporting low-pass, high-pass, and band-pass responses. Filter coefficients can be loaded via serial interface, and the block also supports offset correction, fine gain adjustment (0.05 dB steps), and decimation by 2, 4, or 8-all applied post-conversion. By default, this block is bypassed, allowing raw data output when maximum throughput is required.

What is the package type and thermal performance of the ADS62P25IRGCT?

The ADS62P25IRGCT is housed in a 64-pin QFN package (RGC designation) measuring 9 mm × 9 mm with an exposed thermal pad. Its thermal characteristics are characterized per JEDEC standards: θJA = 23.17 °C/W (0 LFM airflow) and θJC = 22.1 °C/W when mounted on a 4-layer PCB with 2 oz. copper and soldered thermal pad. This enables reliable operation at full 799 mW analog power dissipation within the –40°C to 85°C industrial temperature range.
