Overview
The ADS122U04IPW is a 24-bit Sigma-Delta analog-to-digital converter (ADC) from Texas Instruments, housed in a 16-pin TSSOP package. It features four input channels with a maximum sampling rate of 2 kSPS and supports both differential and single-ended inputs. The device operates on analog and digital supply voltages ranging from 2.3 V to 5.5 V, with an operating temperature range of -40°C to +125°C. Key integrated components include a programmable gain amplifier (PGA), internal voltage reference, excitation current sources (iDACs), GPIO, oscillator, and temperature sensor. Communication is handled via a UART interface.
Feature Summary
- Integrates a programmable gain amplifier and excitation current sources to reduce external component count for small signal measurements.
- Includes built-in 50/60 Hz rejection capabilities to filter power line interference effectively.
- Features a compact surface-mount design suitable for space-constrained applications.
Applications
- Industrial process control systems requiring high-resolution data acquisition.
- Weight scales and load cell measurement interfaces.
- Thermocouple and RTD temperature monitoring circuits.
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 requirements align with the host microcontroller's communication protocols. Validate that the 2.3 V to 5.5 V supply range matches the system power architecture.
Selection Notes
Select this model over variants like ADS122C04 if UART connectivity is preferred over I2C. Consider the ADS122U04IRTER variant if reel packaging is required for automated assembly instead of tubes. Evaluate the ADS112U04 series if 16-bit resolution suffices for lower cost requirements. Ensure the 2 kSPS sampling rate meets the bandwidth needs of the target application signals.
Part Context
This component belongs to the ADS122Uxx family of low-power, small-size ADCs designed for precision measurement applications. It shares architectural similarities with other devices in the series but is distinguished by its UART interface and 24-bit resolution. The IPW suffix specifically denotes the plastic thin-shrink small-outline package type used in this part number.
Replacement Considerations
ADS122U04IRTER: Same electrical specifications with reel packaging instead of tubes.
