ADS1191IPBS TI Analog Front End | 32-TQFP (5x5) | 16-bit, 8 kSPS, Low Power

Product Overview

The ADS1191IPBS is a low-power, 16-bit delta-sigma (ΔΣ) analog-to-digital converter (ADC) with an integrated programmable gain amplifier (PGA), internal reference, and an onboard oscillator. It is designed for high-precision, low-bandwidth measurement applications such as biopotential measurements (ECG, EEG) and industrial process control. The device operates from a single 2.7V to 5.25V supply and features a maximum data rate of 8 kSPS. The ADS1191IPBS is housed in a compact 32-pin TQFP (5x5 mm) package, making it ideal for space-constrained designs.
