ADS7846IPWRSV

Overview

The ADS7846IPWRSV is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.2V to 5.25V and features an internal 2.5V reference. The device supports a throughput rate of up to 125 kHz via a QSPI/SPI 3-wire interface. Key functionalities include direct battery measurement (0V to 6V), on-chip temperature sensing, and touch-pressure detection. It is designed for low-power applications with auto power-down capabilities.

Feature Summary

12-bit resolution with 125 kHz throughput rate
Integrated 2.5V internal reference and 6-channel multiplexer
Supports direct battery monitoring (0V-6V) and temperature measurement
QSPI/SPI 3-wire serial interface with auto power-down mode

Applications

Personal Digital Assistants (PDAs)
Portable instruments
Point-of-sale terminals
Cellular phones
Touch screen monitors

Procurement Notes

Verify the specific suffix IPWRSV against the manufacturer's current Package Option Addendum to confirm pinout compatibility and package dimensions. Ensure the component meets RoHS compliance requirements for the intended market. Check for end-of-life notifications or discontinuation notices prior to finalizing procurement plans.

Selection Notes

Select this component when a 12-bit ADC with integrated touch screen drivers and battery monitoring is required. It is compatible with the ADS7843 pinout for easy upgrades. Consider the differential reference mode for ratiometric touch screen measurements to minimize error from switch on-resistance.

Part Context

The ADS7846 is a next-generation version of the industry-standard ADS7843. It maintains 100% pin compatibility, allowing it to drop into existing sockets. This design facilitates software-only upgrades to access additional features such as direct battery measurement and temperature sensing without hardware redesign.

Replacement Considerations

The ADS7846 is 100% pin-compatible with the ADS7843. No hardware changes are required for replacement, only potential software adjustments to utilize new features.
