ADS61B29IRGZ25

Analog To Digital Converters (ADC) Overview

The ADS61B29IRGZ25 is a dual-channel, high-speed analog-to-digital converter manufactured by Texas Instruments. It features a pipelined architecture with 14-bit resolution and supports sampling rates up to 250 MSPS. The device accepts differential analog inputs and provides outputs via DDR LVDS and parallel CMOS interfaces. It operates on a single 3.3V supply voltage for both analog and digital sections. The component is housed in a 64-pin VQFN package with an exposed pad, designed for surface-mount installation. It functions within a commercial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '25' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure that the design accounts for the required power supply decoupling and thermal management associated with the 64-VQFN package. Cross-reference the JESD204B or parallel interface requirements with the system controller before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization at 250 MSPS is required. Compare performance metrics such as SNR and SFDR against alternative TI models like the ADC32Jxx series if lower speed is acceptable. Verify that the system can support the DDR LVDS or parallel CMOS data rates. Confirm that the 3.3V single-supply requirement aligns with the available power rails in the target application.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS61B family of high-performance dual-channel ADCs from Texas Instruments. It is positioned alongside other devices in the ADS6x series, offering a balance between high sampling speed and resolution. The device is distinct from the ADC32J series, which utilizes JESD204B interfaces, whereas the ADS61B offers flexible parallel and LVDS options.
