ADS1292RIPBSR

Analog Front End (AFE) Overview

The ADS1292RIPBSR is a low-power, two-channel analog front-end (AFE) designed for biopotential measurements. It integrates two 24-bit delta-sigma analog-to-digital converters (ADCs), each with a programmable gain amplifier (PGA). The device includes an internal reference voltage and oscillator, supporting data rates up to 8 kSPS. It features flexible input multiplexers for lead-off detection and temperature sensing. The component operates within a supply voltage range of 2.7 V to 3.6 V and is housed in a 32-pin TSSOP package.

Analog Front End (AFE) Feature Summary

• Dual 24-bit ADCs with integrated PGA
• Internal reference and oscillator
• Supports data rates up to 8 kSPS
• Integrated lead-off detection capability

Analog Front End (AFE) Applications

• Portable ECG systems
• Wearable health monitors
• Ambulatory monitoring devices

Analog Front End (AFE) Procurement Notes

Verify the specific suffix IPBSR against the manufacturer's current datasheet to confirm the package type and tape-and-reel specifications. Ensure compatibility with the target system's SPI interface timing requirements before procurement.

Analog Front End (AFE) Selection Notes

Select this component when a dual-channel solution with high resolution is required for biopotential signals. Compare power consumption at the desired sampling rate against single-channel alternatives if channel count can be reduced. Verify that the 32-pin TSSOP footprint fits the PCB layout constraints.

Analog Front End (AFE) Part Context

This part belongs to the ADS129x family of analog front-ends from Texas Instruments. It serves as a specialized solution for medical-grade signal acquisition, offering higher integration than discrete ADC and amplifier combinations. It complements other members like the ADS1292RIRSMR which uses a different package format.

Analog Front End (AFE) Replacement Considerations

Direct replacements include ADS1292RIRSMR for pin-compatible packaging differences or ADS1292IPBSR for non-'R' variants. Verify functional equivalence regarding lead-off detection and PGA settings when substituting.
