ADS1192IRSMT

Analog Front End (AFE) Overview

The ADS1192IRSMT is a low-power, two-channel analog front-end (AFE) designed for biopotential measurements. It integrates two low-noise programmable gain amplifiers (PGAs) and two high-resolution 16-bit sigma-delta analog-to-digital converters (ADCs). The device supports data rates up to 8 kSPS and operates with an analog supply voltage range of 2.7 V to 5.25 V and a digital supply voltage range of 1.7 V to 3.6 V. It is housed in a 32-pin VQFN package rated for operation from -40°C to +85°C.

Analog Front End (AFE) Feature Summary

• Integrates two low-noise PGAs and two 16-bit ADCs
• Supports data rates up to 8 kSPS
• Low power consumption suitable for portable applications

Analog Front End (AFE) Applications

• Biopotential measurement systems
• Portable medical devices
• Wearable health monitors

Analog Front End (AFE) Procurement Notes

Verify the specific suffix 'IRSMT' against the manufacturer's official documentation to confirm the tape-and-reel packaging configuration and temperature grade. Ensure compatibility with the required analog and digital supply voltages during component sourcing.

Analog Front End (AFE) Selection Notes

Select this component when a dual-channel solution with 16-bit resolution is required for biopotential signals. Compare performance metrics such as input referred noise and power consumption against other members of the ADS119x family if channel count or resolution requirements differ.

Analog Front End (AFE) Part Context

This part belongs to the Texas Instruments ADS119x series of analog front-ends. It shares architectural similarities with other devices in the family, such as the ADS1191 and ADS1192IRSMR, differing primarily in package type and specific ordering suffixes defined by the manufacturer.

Analog Front End (AFE) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADS1191 and ADS1192 variants. Verify that the substitute part number matches the required package style and electrical specifications before implementation.
