ADS112U04IPWR

Analog To Digital Converters (ADC) Overview

The ADS112U04IPWR is a low-power, 16-bit analog-to-digital converter (ADC) from Texas Instruments, featuring four channels and a maximum sampling rate of 2 kSPS. It utilizes a sigma-delta architecture with an internal reference voltage of 2.048 V and operates on supply voltages ranging from 2.3 V to 5.5 V for both analog and digital domains. The device supports differential or single-ended inputs and communicates via a UART interface. Housed in a TSSOP-16 package, it offers a gain error of 0.01% and consumes 1.4 mW of power. It functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated excitation current sources (iDACs) for sensor biasing
• Built-in programmable gain amplifier (PGA) and temperature sensor
• Supports 50/60 Hz line frequency rejection

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Portable instrumentation
• Weight scales and load cell measurements

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPWR against official datasheets to confirm the tape-and-reel packaging variant. Ensure compatibility with UART communication protocols and validate that the TSSOP-16 footprint matches the design layout. Confirm RoHS compliance status through manufacturer documentation before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution with four input channels is required alongside low power consumption. The UART interface simplifies connectivity compared to SPI alternatives. Consider the 2.3 V to 5.5 V operating range for flexibility in system power design. Verify that the 2 kSPS data rate meets application bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS112U04 series, designed for precision applications requiring multiple channels. It shares architectural similarities with other devices in the family but differs in interface type and packaging. The IPWR suffix specifically denotes the reel-packaged version of the TSSOP-16 component.

Analog To Digital Converters (ADC) Replacement Considerations

ADS112U04IPW is the tube-packaged equivalent of the same functional device. ADS112C04 variants offer I2C interfaces instead of UART. ADS112S14 provides higher speed but fewer features per channel.
