ADS4126IRGZT

Analog To Digital Converters (ADC) Overview

The ADS4126IRGZT is a dual-channel, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at a sampling rate of 160 MSPS and utilizes a pipeline architecture. The device features differential inputs and supports parallel CMOS or LVDS digital interfaces. It requires a 1.8 V analog supply and a 1.8 V digital supply. Key performance metrics include a typical signal-to-noise ratio (SNR) of 70.5 dB and an effective number of bits (ENOB) of 11.3 bits. The component is housed in a 64-pin VQFN package with exposed pad and functions within a junction temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRGZT' against the manufacturer's current datasheet to confirm the tape-and-reel packaging configuration and industrial temperature grade. Ensure that the ordering part number matches the exact pinout and electrical specifications required for the target design, as minor revisions may affect compatibility.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel solution is required to save board space compared to single-channel alternatives. Compare the 160 MSPS speed and 12-bit resolution against system bandwidth requirements. Evaluate the power budget constraints relative to the device's total dissipation. Consider the availability of evaluation modules for initial prototyping and validation of the ADC performance in the specific application environment.

Analog To Digital Converters (ADC) Part Context

The ADS4126 belongs to the ADS41xx family of low-power, high-speed ADCs from Texas Instruments. This series is designed to bridge the gap between moderate speed and high resolution. It shares architectural similarities with the ADS4125 and ADS4128 but offers dual channels in a compact form factor. The family is commonly used in applications demanding balanced performance between speed and power efficiency.

Analog To Digital Converters (ADC) Replacement Considerations

Potential substitutes within the same product line include the ADS4125 (single channel) or ADS4128 (dual channel, different speed). Cross-reference with the ADS4226 for similar dual-channel specifications. Verify pin-to-pin compatibility and electrical parameter overlaps before substitution.
