The ADS1291IRSMT is a 24-bit, 1-channel delta-sigma analog front end (AFE) from Texas Instruments, optimized for low-power biopotential measurements such as electrocardiogram (ECG) applications. It integrates a programmable gain amplifier (PGA), internal reference, and oscillator, reducing external component count. Key specifications include 24-bit resolution, 495 µW power consumption, input-referred noise of 8 µVpp (at 150 Hz BW, G=6), 120 dB CMRR, and input bias current of 200 pA. The SPI interface allows easy connection to microcontrollers. The programmable gain can be set to 1, 2, 3, 4, 6, 8, or 12. Data rate is selectable from 125 SPS to 8 kSPS. The device operates from an analog supply of 2.7 V to 5.25 V and a digital supply of 1.7 V to 3.6 V. Housed in a 32-VFQFN Exposed Pad package (32-VQFN, 4 mm × 4 mm), it is suitable for surface-mount assembly and operates over -40°C to +85°C. Typical applications include portable ECG monitors, fitness wearables, and other biomedical sensors requiring high precision and low power.
