ADS1292R in TI ADS1115 / ADS1118 ADC Family
The ADS1292R by Texas Instruments is a highly integrated, low-power analog front-end designed specifically for biopotential measurements. It incorporates two simultaneous-sampling, 24-bit delta-sigma ADCs alongside an integrated respiration impedance measurement system and a programmable gain amplifier. By consolidating the signal chain for ECG and respiration rate monitoring into a single chip, it reduces board space and power consumption in medical instrumentation and wearable diagnostic devices.
Variants in This Sub-Family
The ADS1292R variant is distinguished from the base ADS1292 by the inclusion of integrated respiration impedance measurement hardware. Within the broader family, the ADS1291 offers a single-channel solution for basic monitoring, while the ADS1292 provides dual-channel capabilities without the respiration circuitry. All variants share a common architecture and command set, allowing developers to scale designs based on the number of required leads and diagnostic depth.
