ADS1119IRTER

Analog To Digital Converters (ADC) Overview

The ADS1119IRTER is a four-channel, 16-bit analog-to-digital converter (ADC) from Texas Instruments, utilizing sigma-delta architecture. It operates within an analog and digital supply voltage range of 2.3 V to 5.5 V and features an internal 2.048 V reference. The device supports I2C communication with sampling rates up to 1 kS/s and accepts both differential and single-ended inputs. Packaged in a 16-pin WQFN (3x3 mm) format, it functions across a temperature range of -40°C to +125°C. Key specifications include a power dissipation of approximately 1 mW and integrated programmable gain amplifier capabilities.

Analog To Digital Converters (ADC) Feature Summary

• Integrated programmable gain amplifier for flexible input signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RTER' corresponds to the reel packaging configuration when sourcing. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure handling procedures account for moisture sensitivity level 2, as indicated in manufacturer documentation. Cross-reference the Mouser part number 595-ADS1119IRTER for accurate distributor identification.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a compact, low-power solution with multiple channels is required. The internal reference and oscillator simplify board layout compared to external reference designs. Consider the 16-WQFN package constraints for thermal management and PCB space. Verify that the I2C interface speed matches the microcontroller capabilities in the target system design.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS1119 series of general-purpose delta-sigma ADCs. It shares architectural similarities with other devices in the family but is distinguished by its specific pinout and packaging options. The IRTER designation indicates a tape-and-reel variant intended for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1119IRTET serves as a cut-tape alternative offering identical electrical performance. Other members of the ADS1119 family may provide different packaging or slight parameter variations. Verify pin compatibility before substituting with related models from the same product line.
