Texas Instruments ADS62P23IRGCT REEL

Overview

ADS62P23IRGCT REEL from Texas Instruments is a dual-channel, 12-bit analog-to-digital converter with 80 MSPS maximum sampling rate, DDR LVDS or parallel CMOS outputs, and integrated digital processing block supporting decimation (2/4/8), 24-tap programmable filters, and fine gain correction in 0.05 dB steps. It operates over –40°C to 85°C and targets high-performance signal acquisition in wireless infrastructure and radar.

For engineers reviewing the ADS62P23IRGCT REEL datasheet, ADS62P23IRGCT REEL pinout, ADS62P23IRGCT REEL application, or ADS62P23IRGCT REEL equivalent, key selection criteria include its 80 MSPS sample rate, 93 dBc SFDR at 10 MHz input (0 dB gain), 71.5 dBFS SINAD at same condition, 64-pin QFN package, and support for internal/external reference and coarse/fine gain control.

Technical Context

The ADS62P23IRGCT REEL implements a dual 12-bit pipeline ADC architecture with internal sample-and-hold and low-jitter clock buffer, enabling high SNR and SFDR at RF input frequencies up to 450 MHz analog bandwidth. Its digital processing block includes offset correction, fine gain adjustment, and configurable decimation and filtering - all programmable via serial interface or parallel pins.

It supports flexible clocking with sine, LVPECL, LVDS, or LVCMOS inputs down to 400 mV_PP, includes a clock duty cycle stabilizer, and offers two output modes: DDR LVDS (3.3 V DRVDD) or parallel CMOS (1.8–3.6 V DRVDD). Power management includes global powerdown (50–75 mW) and channel-specific standby modes.

FAQ

What is the maximum sampling rate supported by the ADS62P23IRGCT REEL?

The ADS62P23IRGCT REEL supports a maximum sampling rate of 80 MSPS, as specified in the TI SLAS576C datasheet. This rate is guaranteed across the full industrial temperature range (–40°C to 85°C) with AVDD = 3.3 V and proper clock conditioning. Exceeding this rate may result in degraded AC performance or non-compliance with timing specifications.

Does the ADS62P23IRGCT REEL support both LVDS and CMOS digital outputs?

Yes, the ADS62P23IRGCT REEL supports both DDR LVDS and parallel CMOS outputs. Output mode is selected via the SEN pin voltage level during power-up. LVDS operation requires DRVDD = 3.0–3.6 V and 100 Ω differential termination; CMOS supports DRVDD = 1.8–3.6 V and standard logic interfacing without termination resistors.

What is the SFDR performance of the ADS62P23IRGCT REEL at 10 MHz input frequency?

At 10 MHz input frequency and 0 dB coarse gain, the ADS62P23IRGCT REEL achieves 93 dBc spurious-free dynamic range (SFDR), as measured under typical conditions (AVDD = 3.3 V, internal reference, –1 dBFS input). This value is confirmed in Table 1 of the SLAS576C datasheet and represents worst-case spur suppression across the device family.

Can the ADS62P23IRGCT REEL operate with an external reference voltage?

Yes, the ADS62P23IRGCT REEL supports external reference operation. When configured via the SCLK pin voltage, it accepts an external reference applied to the VREF pins. The internal reference is disabled in this mode, and the device maintains full DC accuracy specs (e.g., ±2 mV offset error) provided the external reference meets noise and stability requirements outlined in the datasheet.

What package type and thermal characteristics does the ADS62P23IRGCT REEL use?

The ADS62P23IRGCT REEL uses a 64-pin QFN package (RGC designation, 9 mm × 9 mm) with exposed thermal pad. Its thermal resistance is θ_JA = 23.17 °C/W (0 LFM air flow) and θ_JC = 22.1 °C/W when mounted on a JEDEC-standard four-layer PCB with 2 oz. copper and direct pad soldering - enabling reliable operation at full 594 mW analog power dissipation.
