ADS112U04IPW

Analog To Digital Converters (ADC) Overview

The ADS112U04IPW is a low-power, 16-bit analog-to-digital converter (ADC) from Texas Instruments, housed in a TSSOP-16 package. It features a sigma-delta architecture with four channels supporting differential or single-ended inputs. The device operates on analog and digital supply voltages ranging from 2.3 V to 5.5 V and supports a maximum sampling rate of 2 kSPS. Key electrical specifications include a gain error of 0.01%, an internal reference voltage of 2.048 V, and a typical power consumption of 1.4 mW. It utilizes a UART interface for communication and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated programmable gain amplifier (PGA) and excitation current sources (iDACs) for sensor signal conditioning
• Built-in 50/60 Hz rejection capability to suppress power line interference
• On-chip temperature sensor and oscillator for system monitoring and timing

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel precision measurement
• Portable instrumentation benefiting from low power consumption and small size
• Weight scales and load cell applications utilizing integrated excitation sources

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPW corresponds to the TSSOP-16 tube packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the UART interface compatibility matches the host microcontroller design requirements for successful deployment.

Analog To Digital Converters (ADC) Selection Notes

Select this component for designs requiring four channels with moderate speed and high accuracy. The internal PGA reduces external component count compared to discrete solutions. Consider the UART interface constraint if SPI or I2C connectivity is preferred by the system architecture. Evaluate the 1.4 mW power dissipation against thermal constraints in enclosed enclosures.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS112U04 series, which provides low-power, small-size ADC solutions. It shares architectural similarities with other members like the ADS112C04 but differs in interface type, using UART instead of I2C. The family targets cost-sensitive industrial applications where board space and power efficiency are critical design parameters.

Analog To Digital Converters (ADC) Replacement Considerations

ADS112U04IRTET offers identical functionality in a WQFN-16 package with tape-and-reel packaging. ADS112C04IPW provides similar performance but uses an I2C interface instead of UART. Verify pinout and interface compatibility before substituting these alternatives.
