ADS1119IRTET

Analog To Digital Converters (ADC) Overview

The ADS1119IRTET is a low-power, four-channel, 16-bit analog-to-digital converter (ADC) from Texas Instruments. It utilizes a sigma-delta architecture with an internal oscillator and programmable gain amplifier (PGA). The device supports I2C digital interface communication and accepts differential or single-ended inputs. It operates on analog and digital supply voltages ranging from 2.3 V to 5.5 V. Key specifications include a maximum sampling rate of 1 kSPS, an internal reference voltage of 2.048 V, and power dissipation of approximately 1 mW. It functions within a temperature range of -40°C to +125°C and is housed in a 16-WQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to ensure correct packaging and temperature grade. Confirm that the WQFN-16 package dimensions match the target PCB footprint. Check for moisture sensitivity level requirements during storage and handling. Ensure the I2C address configuration aligns with the system bus topology.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate speed and high resolution is required for multiple channels. The integrated PGA reduces bill of materials by eliminating external amplifiers. Verify that the I2C interface speed meets the system timing constraints. Consider the thermal performance within the specified operating temperature range for the final enclosure design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1119 family of precision ADCs. It shares the same core architecture and pinout with variants like the ADS1119IRTER, differing primarily in packaging format. The series is designed for general-purpose applications where space and power are constrained but accuracy remains critical.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1119IRTER serves as a direct functional equivalent with identical electrical characteristics, differing only in the reel versus cut-tape packaging format. No other cross-model substitutes share the exact combination of four channels, 16-bit resolution, and I2C interface within this specific form factor.
