The ADS1191IRSMR from Texas Instruments is a 16-bit, single-channel Analog Front End (AFE) specifically designed for ECG and other biopotential measurement applications. This device integrates essential features like a programmable gain amplifier (PGA), internal reference, and an onboard oscillator, enabling the creation of compact and low-power medical instrumentation systems.
Key electrical specifications include a low power consumption of 335 µW/channel, input-referred noise of 24 µV PP, and a data rate ranging from 125 SPS to 8 kSPS. It supports an SPI-compatible serial interface and operates over a wide temperature range of -40°C to +85°C. The analog supply voltage can range from 2.7 V to 5.25 V, while the digital supply is between 1.7 V and 3.6 V.
The ADS1191IRSMR is available in a 32-VQFN (4x4 mm) package and is designed for surface mount applications. Its high level of integration and performance make it suitable for portable, low-power medical devices such as 1-lead ECGs and ECG patches, contributing to reduced size, power, and overall system cost.
