ADS112C04IPWR

Analog To Digital Converters (ADC) Overview

The ADS112C04IPWR is a low-power, 16-bit analog-to-digital converter (ADC) from Texas Instruments, featuring four differential or single-ended input channels. It utilizes a sigma-delta architecture with an integrated programmable gain amplifier (PGA), internal oscillator, and temperature sensor. The device supports I2C digital interfaces and operates on supply voltages ranging from 2.3 V to 5.5 V for both analog and digital domains. It offers a maximum sampling rate of 2 kSPS and includes excitation current sources (iDACs). Key electrical specifications include a gain error of 0.01%, power dissipation of 1.4 mW, and a reference voltage of 2.048 V. The component is housed in a TSSOP-16 package and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated excitation current sources (iDACs) for direct sensor excitation
• Built-in 50/60 Hz rejection capability for noise reduction
• On-chip programmable gain amplifier and temperature sensor

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel precision measurement
• Portable medical devices utilizing low-power signal acquisition
• High-resolution electronic weighing scales

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IPWR' confirms the tape-and-reel packaging format distinct from tube-packaged variants like 'IPW'. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Ensure the I2C interface configuration matches the host microcontroller requirements. Validate that the operating voltage range aligns with the system's power supply rails.

Analog To Digital Converters (ADC) Selection Notes

Select this model when four independent channels are required alongside integrated sensor excitation capabilities. The I2C interface simplifies board layout compared to SPI alternatives. Consider the 16-bit resolution and 2 kSPS speed as sufficient for most static or slow-varying industrial signals. Evaluate the TSSOP-16 footprint against available PCB space constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS112C04 series, which provides high-precision data conversion solutions. It shares architectural similarities with other members of the family but is distinguished by its specific pinout, interface type, and channel count. The IPWR suffix indicates a reel-based packaging option suitable for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS112U04IPW serves as a functional alternative within the same family, offering similar resolution and power characteristics. Note that the U-series variant utilizes a UART interface instead of I2C, requiring significant firmware and hardware redesign if substituted directly.
