ADS122C04IPWR

Overview

The ADS122C04IPWR is a 24-bit, low-power analog-to-digital converter (ADC) from Texas Instruments, housed in a 16-pin TSSOP package. It features four differential or single-ended inputs and supports an I2C digital interface. The device operates on a supply voltage range of 2.3 V to 5.5 V for both analog and digital domains. It delivers a sampling rate of up to 2 kSPS with a sigma-delta architecture. Key integrated features include a programmable gain amplifier (PGA), internal reference, temperature sensor, and excitation current sources (iDACs). The component functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a programmable gain amplifier and internal reference to simplify signal conditioning.
• Includes built-in excitation current sources suitable for direct sensor interfacing.
• Features an integrated temperature sensor for system monitoring.
• Supports flexible input configurations via multiplexer for differential or single-ended signals.

Applications

• Industrial process control systems requiring high-resolution data acquisition.
• Battery-powered instrumentation utilizing low power consumption modes.
• Weight scale applications leveraging integrated excitation current sources.
• Medical equipment demanding precise signal measurement in compact form factors.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the requested part number matches the exact pinout and electrical characteristics defined in the latest product documentation before finalizing procurement orders.

Selection Notes

Select this component when four channels of 24-bit resolution are required with minimal external components. The integrated PGA and iDACs reduce bill-of-materials complexity. Ensure the application requires I2C communication and fits within the specified voltage and temperature operating ranges provided in the technical specifications.

Part Context

This device belongs to the ADS122C04 family of precision ADCs designed for low-power, small-footprint applications. It shares architectural similarities with other members of the series but offers four input channels compared to lower-channel variants. The IPWR suffix indicates the surface-mount TSSOP-16 package configuration used for automated assembly processes.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified alternative part numbers. Ensure any substitute maintains compatibility with the I2C interface protocol and physical footprint requirements of the existing design layout.
