ADS1191IPBSR Description

Short technical summary and product information.

The ADS1191IPBSR is a 16-bit, 1-channel low-power analog front end (AFE) from Texas Instruments, designed for biopotential measurements such as electrocardiogram (ECG) in portable medical, sports, and fitness devices. It integrates a delta-sigma analog-to-digital converter (ADC) with a programmable gain amplifier (PGA), internal reference, and oscillator, reducing external component count and system size.

 

Key specifications include a resolution of 16 bits, a single input channel, and an SPI-compatible serial interface. The device achieves a typical power consumption of 335 µW per channel, making it suitable for battery-operated applications. Input-referred noise is 24 µVpp at 150 Hz bandwidth with a gain of 6, and common-mode rejection ratio (CMRR) is -95 dB typical. The programmable gain can be set to 1, 2, 3, 4, 6, 8, or 12, and the data rate is adjustable from 125 SPS to 8 kSPS.

 

The ADS1191IPBSR operates from a unipolar or bipolar analog supply of 2.7 V to 5.25 V and a digital supply of 1.7 V to 3.6 V. Input bias current is typically 1 nA. Additional features include built-in right leg drive amplifier, lead-off detection, test signals, and flexible power-down/standby modes. The device is packaged in a 32-TQFP (5x5 mm) surface-mount package and operates over the industrial temperature range of -40°C to +85°C.
