Product Overview
The ADS1292 is a Texas Instruments 2-channel biopotential analog front-end in the Signal_Chain category. Its signal path is built around simultaneous-sampling 24-bit delta-sigma ADCs with a flexible per-channel input multiplexer. Each channel can be independently connected to internal test signals, a temperature monitoring signal, and lead-off detection signals.
The device supports programmable gain settings of 1, 2, 3, 4, 6, 8, or 12, output data rates from 125 SPS to 8 kSPS, and 120 dB common-mode rejection. Specified parameters include 335 uW/channel power consumption, 8 uVPP input-referred noise over 150-Hz bandwidth at G = 6, and 200 pA input bias current.
Integrated functions include a built-in reference, built-in oscillator, SPI-compatible serial digital interface, built-in right leg drive amplifier, built-in lead-off detection, internally generated test signals, and an internally generated temperature signal. The ADS1292 operates from 2.7 V to 5.25 V analog supplies and 1.7 V to 3.6 V digital supply over -40°C to +85°C. Package options are 32-pin TQFP, 5.00 mm x 5.00 mm, and 32-pin VQFN, 4.00 mm x 4.00 mm.

Procurement Notes
When requesting a quote for ADS1292, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
