ADS4125IRGZT

Analog To Digital Converters (ADC) Overview

The ADS4125IRGZT is a single-channel, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a sampling rate of 125 MSPS and utilizes a pipeline architecture. The device accepts differential analog inputs and provides parallel LVDS digital outputs. It requires 1.7 V to 1.9 V for both analog and digital power supplies. Key performance metrics include an SNR of 68 dB, SFDR of 76 dB, and SINAD of 67.9 dB at Nyquist. The effective number of bits (ENOB) is 11.0 bits. Power consumption is 300 mW. It functions within a temperature range of -40°C to +85°C and is housed in a 48-VQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure compatibility with required voltage levels and clocking schemes before integration. Confirm RoHS compliance status through manufacturer documentation. Check for moisture sensitivity level requirements during storage and handling procedures.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed 12-bit ADC is required. Compare against ADS4149 for higher resolution or ADS4122 for lower speed options. Evaluate power budget constraints as this device consumes 300 mW. Ensure the system supports parallel LVDS interfaces for data transfer.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS41xx family of low-power, high-speed ADCs from Texas Instruments. These devices are designed for applications requiring moderate resolution and high sampling rates. The family includes variants with different resolutions and channel counts, sharing similar packaging and interface characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

ADS4122IRGZT: Lower speed option (125 MSPS, 12-bit). ADS4149IRGZT: Higher resolution option (250 MSPS, 14-bit). Verify pinout and software compatibility before substitution.
