Texas Instruments ADS5232IPAGTG4

Overview

ADS5232IPAGTG4 from Texas Instruments is a dual, 12-bit, 65MSPS pipelined analog-to-digital converter operating from a single +3.3V supply. It features internal reference, 3-state digital outputs, over-range indicators per channel, and PLL-based timing/duty-cycle adjustment. Used in high-fidelity communications IF processing and medical imaging systems requiring simultaneous sampling with low DNL (±0.3LSB) and high SNR (70.7dBFS at 5MHz).

For engineers reviewing the ADS5232IPAGTG4 datasheet, ADS5232IPAGTG4 pinout, ADS5232IPAGTG4 application, or ADS5232IPAGTG4 equivalent, this page delivers verified specifications, TQFP-64 package mapping, dual-channel ADC timing behavior, serial register control details, and validated alternative parts for multichannel data acquisition designs.

Technical Context

The ADS5232IPAGTG4 employs a switched-capacitor pipelined architecture with digital error correction logic to guarantee no missing codes and ±0.3LSB DNL. Each channel includes a differential sample-and-hold amplifier with 300MHz input bandwidth and transformer-coupled input support.

It integrates a PLL for clock duty-cycle adjustment (45–55% range), supports both internal (2.0V ref span) and external reference modes, and provides independent output enable (OEA/OEB) and over-range flags (OVRA/OVRB) per channel - enabling synchronized multichannel gain control and multiplexed board-level testing.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel, high-speed ADC applications.

Compared with ADS5232IPAGTG4, ADS5231IPAG offers identical per-channel specs in single-channel form for cost-sensitive deployments, while ADS5270IPFP delivers higher resolution at reduced speed and without PLL-based clock cleanup - making it appropriate for precision instrumentation rather than communications IF sampling.

FAQ

What is the maximum sample rate supported by the ADS5232IPAGTG4 with its internal PLL enabled?

The ADS5232IPAGTG4 supports up to 65MSPS when the internal PLL is enabled. At this rate, it maintains 70.7dBFS SNR at 5MHz input frequency and 1.0ps aperture jitter. The PLL automatically adjusts clock duty cycle to 45–55%, ensuring stable timing margins without external clock conditioning circuitry - a key advantage for compact IF sampling designs.

Does the ADS5232IPAGTG4 support external reference voltage, and what are the valid voltage ranges?

Yes, the ADS5232IPAGTG4 supports external reference mode via REFT and REFB pins. Valid ranges are REFT = 1.875V to 2.05V and REFB = 0.95V to 1.125V, yielding a 0.75V to 1.1V reference span. This mode reduces total power to 335mW and improves tracking accuracy in multichip systems - confirmed in the Electrical Characteristics table under "External Reference" conditions.

How does the serial interface of the ADS5232IPAGTG4 function, and which pins are involved?

The ADS5232IPAGTG4 serial interface uses three dedicated pins when SEL = 1: SEN (pin 41) as write-enable strobe, SCLK (pin 42) as serial clock, and SDATA (pin 45) as data-in. It supports MSB-first 8-bit register writes for configuring output format, channel power-down, and PLL enable/disable - all documented in the Serial Register Map on page 9 of the SBAS294A datasheet.

What is the purpose of the OVRA and OVRB pins on the ADS5232IPAGTG4, and how are they used in system design?

OVRA (pin 39) and OVRB (pin 9) are open-drain over-range indicator flags per channel, asserting when input exceeds full-scale range. In receiver systems, they drive front-end VGA gain control loops to prevent clipping - confirmed by the Applications section listing "communications base stations" and "test equipment" as primary use cases requiring dynamic range management.

Can the ADS5232IPAGTG4 operate with a 2.5V supply, or is +3.3V mandatory?

No - the ADS5232IPAGTG4 requires AVDD and VDRV supplies between 3.0V and 3.6V per Recommended Operating Conditions. Absolute maximum ratings specify –0.3V to +3.8V, but functional operation is only guaranteed within the 3.0–3.6V range. Operation below 3.0V risks failure to meet AC specs including SNR, SFDR, and DNL - explicitly stated in Section 3 of the SBAS294A datasheet.
