ADS7038IRTET

Analog To Digital Converters (ADC) Overview

The ADS7038IRTET is a Texas Instruments integrated circuit featuring an 8-channel, 12-bit successive approximation register (SAR) analog-to-digital converter. It operates with a sampling rate of 1 MSPS and supports single-ended inputs via an internal multiplexer. The device utilizes a 16-pin WQFN package with dimensions of 3x3 mm. It requires an analog supply voltage ranging from 2.35 V to 5.5 V and a digital supply voltage between 1.65 V and 5.5 V. Key performance metrics include a signal-to-noise ratio of 72.9 dB, differential nonlinearity of 0.3 LSB, integral nonlinearity of 0.5 LSB, and a gain error of 0.05% FSR. The component functions within a temperature range of -40°C to +125°C.

• Data acquisition modules in automated testing equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to ensure correct packaging and temperature grade. Confirm that the requested part matches the exact pinout and electrical specifications required for the target design. Cross-reference manufacturer datasheets to validate RoHS compliance and moisture sensitivity levels before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight single-ended channels are required at speeds up to 1 MSPS. Ensure the application can accommodate the specified analog and digital supply voltage ranges. Consider the 16-WQFN package size constraints during PCB layout. Verify that the input signal characteristics align with the single-ended input configuration and do not exceed the absolute maximum ratings.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7038 family of 12-bit SAR ADCs designed for low-power, multi-channel applications. It shares architectural similarities with other members like the ADS7138 but differs in interface type and sampling speed. The IRTET suffix indicates a specific reel-based packaging format suitable for surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7038IRTER is a verified substitute offering identical electrical specifications and functionality, differing only in the tape-and-reel packaging format rather than the component itself.
