ADS4128IRGZR

Analog To Digital Converters (ADC) Overview

The ADS4128IRGZR is a single-channel, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at a sampling rate of 200 MSPS using a pipeline architecture. The device accepts differential analog inputs and provides data output via parallel CMOS or LVDS interfaces. It requires a 3.3 V analog supply and a digital supply ranging from 1.7 V to 1.9 V. Key performance metrics include a signal-to-noise ratio (SNR) of 70.9 dB, an effective number of bits (ENOB) of 11.4 bits, and power dissipation of 687 mW. The component is housed in a 48-pin VQFN package with operating temperatures from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRGZR corresponds to the tape-and-reel packaging configuration when sourcing. Confirm that the voltage supply rails match the specified 3.3 V analog and 1.7-1.9 V digital requirements. Ensure the ordering quantity aligns with the manufacturer's standard reel size to avoid cut-tape handling issues during assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed ADC with low power dissipation is required. Compare SNR and SFDR specifications against system dynamic range needs. Verify compatibility with the target FPGA or processor interface logic levels, as the device supports both CMOS and LVDS outputs for flexible integration.

Analog To Digital Converters (ADC) Part Context

The ADS4128 belongs to the ADS412x family of ultralow-power ADCs from Texas Instruments. This series is designed for applications requiring high throughput with minimal power usage. The IRGZR variant specifically denotes the industrial temperature range and reel packaging format within the broader ADS4128 product line.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS4125 is a documented alternative within the same family, offering similar 12-bit resolution but with a lower 125 MSPS sampling rate. Verify interface compatibility and power supply requirements when substituting, as performance characteristics differ between models.
