ADC34J23IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC34J23IRGZ25 is a quad-channel, 12-bit analog-to-digital converter (ADC) from Texas Instruments with an 80 MSPS sampling rate. It utilizes a pipeline architecture and operates on a single 1.8-V supply. The device features a JESD204B serial interface supporting up to 3.2 Gbps, internal dither for improved SFDR, and multi-chip synchronization capabilities via SYSREF. Key electrical parameters include a typical SNR of 70 dBFS at fIN = 70 MHz, an ENOB of 11.4 bits, and a total power dissipation of 584 mW at maximum sampling rates.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as production data per SBAS669A revision January 2015. Confirm package details correspond to VQFN-48 (7 mm × 7 mm). Ensure compatibility with 1.8-V logic levels for digital inputs and outputs. Check for moisture sensitivity level (MSL) requirements during storage and handling.

Analog To Digital Converters (ADC) Selection Notes

Select this model when an 80 MSPS sampling rate is required for 12-bit conversion. Compare against ADC34J22 (50 MSPS), ADC34J24 (125 MSPS), and ADC34J25 (160 MSPS) based on specific bandwidth needs. Consider pin-to-pin compatibility with the 14-bit ADC34J4x family if higher resolution is needed in future designs.

Analog To Digital Converters (ADC) Part Context

Part of the ADC34J2x family, which includes ADC34J22, ADC34J24, and ADC34J25. These devices share similar architectures and packaging but differ in maximum sampling speeds ranging from 50 MSPS to 160 MSPS. The family is designed for high-linearity applications requiring low power consumption and flexible clocking options.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-to-pin compatible with other members of the ADC34J2x family (ADC34J22, ADC34J24, ADC34J25) and the 14-bit ADC34J4x series. Verify sampling rate and resolution requirements before substituting.
