ADS7946SRTER

Analog To Digital Converters (ADC) Overview

The ADS7946SRTER is a dual-channel, 14-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It supports sampling rates up to 2 MSPS with a wide analog input range accommodating both single-ended and pseudo-differential configurations. The device operates on a single supply voltage ranging from 2.7V to 5.25V for the analog section and 1.65V to 5.25V for the digital interface. It features an SPI-compatible serial interface and includes an internal power-on reset circuit. The component is housed in a 16-pin WQFN package designed for surface-mount applications.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel architecture with independent multiplexed inputs
• Ultralow-power consumption optimized for battery-operated systems
• Flexible input configuration supporting single-ended and pseudo-differential modes
• Integrated internal reference and clock options

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation
• Industrial process control data acquisition
• Battery-powered sensor interfaces
• Automotive sensor signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'SRTER' corresponds to the 16-WQFN package and tape-and-reel quantity of 3000 units. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the ordering part number matches the required temperature grade and packaging format for your production line.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel 14-bit resolution at 2 MSPS is required with minimal power usage. Compare against the ADS7945 if lower channel count suffices or the ADS7947 if 12-bit resolution meets system needs. Verify that the input voltage ranges and interface compatibility align with the host microcontroller specifications.

Analog To Digital Converters (ADC) Part Context

The ADS7946 belongs to the ADS794x family of ultralow-power ADCs from Texas Instruments. This series shares architectural similarities with the ADS7945 and ADS7947, differing primarily in resolution and channel count. The SRTER suffix indicates the specific reel packaging variant used for high-volume surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7945 serves as a single-channel alternative within the same family. The ADS7947 offers 12-bit resolution with similar performance characteristics. Cross-reference pinouts and electrical specifications carefully before substitution to ensure functional compatibility.
