ADS7851IRTER

Analog To Digital Converters (ADC) Overview

The ADS7851IRTER is a dual-channel, 14-bit Successive Approximation Register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a maximum sampling rate of 1.5 MSPS and features an internal reference. The device supports both differential and single-ended input configurations via an SPI interface. It requires an analog supply voltage between 4.5 V and 5.5 V and a digital supply voltage ranging from 1.65 V to 5.25 V. Power consumption is specified at 45 mW. The component is housed in a 16-WQFN package with dimensions of 3x3 mm and functions reliably within an operating temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRTER against official datasheets to confirm the reel packaging format and moisture sensitivity level. Ensure compatibility with the target PCB footprint for the 16-WQFN package. Confirm that the digital supply voltage requirements align with the host microcontroller logic levels before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-resolution 14-bit conversion is required alongside true simultaneous sampling capabilities. It is suitable for designs needing flexible input types without complex external multiplexing. Consider the 1.5 MSPS throughput if real-time dynamic analysis of multiple correlated signals is necessary for the application.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS785x family of high-speed, low-power SAR ADCs. It shares architectural similarities with the ADS7850 and ADS7853 but offers distinct performance characteristics regarding sampling speed and input flexibility. The series is designed for precision data acquisition tasks where channel synchronization is critical.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7851IRTET serves as a tape-and-reel alternative with identical electrical specifications. Verify pinout compatibility and thermal performance when substituting between different packaging variants within the same product line.
