ADS1205IRGET

Overview

The ADS1205IRGET is a dual-channel, 16-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It integrates two second-order delta-sigma modulators with a 10 MHz clock rate and a programmable gain amplifier (PGA). The device supports differential or single-ended inputs and offers data rates up to 40 kSPS. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and features a serial interface for digital output. The component is housed in a 16-pin VQFN package and is designed for high-precision applications requiring low power consumption and high noise immunity.

Feature Summary

• Dual-channel architecture with two independent 16-bit delta-sigma modulators
• Programmable Gain Amplifier (PGA) with gains from 1 to 128
• Data rates selectable from 2.5 SPS to 40 kSPS
• Integrated 2.5 V internal reference and oscillator

Applications

• Industrial process control systems
• Weight scales and load cell measurements
• Medical instrumentation such as ECG and blood pressure monitors
• Portable battery-powered measurement devices

Procurement Notes

Verify the specific suffix 'IRGET' corresponds to the tape-and-reel packaging format and industrial temperature range (-40°C to +85°C). Confirm that the 16-VQFN package dimensions match the design footprint requirements. Ensure compatibility with the system's voltage levels for the serial communication interface before integration.

Selection Notes

Select this component when dual-channel precision is required within a compact form factor. Compare against the ADS1203 (single channel) or ADS1204 (four channels) based on input count needs. Consider the integrated PGA if signal conditioning amplification is desired to reduce external component count. Verify that the 10 MHz modulator clock aligns with the target data rate and noise performance specifications.

Part Context

The ADS1205 belongs to the ADS120x family of low-power, 16-bit ADCs from Texas Instruments. This series is optimized for applications demanding high accuracy and low power consumption. The IRGET variant specifically denotes the industrial temperature grade and reel packaging, distinguishing it from tube-packaged or extended temperature variants within the same functional family.
