ADC32J25IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC32J25IRGZ25 is a dual-channel, 12-bit analog-to-digital converter (ADC) from Texas Instruments. It supports sampling rates up to 160 MSPS with a single 1.8-V supply. The device features a JESD204B serial interface compliant with Subclass 0, 1, and 2, supporting data rates up to 3.2 Gbps per lane. Key performance metrics include an SNR of 70.3 dBFS at fIN = 70 MHz and channel isolation of 105 dB. It operates within a temperature range of -40°C to +85°C and is housed in a 48-pin VQFN package measuring 7 mm × 7 mm.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGZ25' against the manufacturer's current documentation to confirm availability and exact pinout configuration. Check for production data status updates as device lifecycles may change. Ensure compatibility with existing system clocks and JESD204B link configurations before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component for high-frequency applications requiring low power and high dynamic range. Compare with ADC32J24 if a lower sampling rate of 125 MSPS is sufficient. Verify that the system can support the required JESD204B lane speeds and that the 48-pin VQFN package fits the PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC32J2x family, which includes variants with different sampling rates such as the ADC32J22 (50 MSPS), ADC32J23 (80 MSPS), and ADC32J24 (125 MSPS). All members share pin-to-pin compatibility and similar architectural features, allowing for design flexibility across different bandwidth requirements.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include ADC32J24IRGZ25 for lower speed applications. Other variants like ADC32J22IRGZ25 and ADC32J23IRGZ25 are also pin-compatible but operate at reduced sampling rates.
