ADS4128IRGZT

Analog To Digital Converters (ADC) Overview

The ADS4128IRGZT is a 12-bit, 200-MSPS ultralow-power analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a pipeline architecture with an internal sample-and-hold amplifier configured at a 1:1 ratio. The device operates on a single 1.7V to 1.9V supply for both analog and digital domains. It accepts differential inputs and provides LVDS parallel output data interfaces. The component is housed in a 48-VQFN package measuring 7x7 mm with an exposed pad, suitable for surface-mount installation. It supports a wide operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and temperature rating. Confirm RoHS compliance status through official manufacturer documentation before integration. Check for recent Product Change Notifications regarding pin definitions or marking changes. Ensure ESD protection protocols are followed during handling due to the sensitive nature of ADC inputs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of high sampling rate and low power consumption is required. Consider the 12-bit resolution and 200-MSPS speed against system bandwidth needs. Evaluate the 48-VQFN package size for PCB layout constraints. Verify that the LVDS interface compatibility matches the downstream FPGA or processor requirements.

Analog To Digital Converters (ADC) Part Context

The ADS4128 belongs to Texas Instruments' ADS41xx family of high-performance ADCs. This series is designed for applications demanding high linearity and low power. The IRGZT variant specifically denotes the industrial temperature range and tape-and-reel packaging format. It complements other devices in the portfolio like the ADS4125 and ADS4126.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS4125IRGZT is a parameter-equivalent alternative within the same product family. Both share similar architectural characteristics but may differ in specific performance metrics or availability. Verify electrical specifications and pinout compatibility before substitution.
