ADS1291IRSMR Description

Short technical summary and product information.

The ADS1291IRSMR from Texas Instruments is a highly integrated, 24-bit Analog Front End (AFE) designed for single-lead ECG and biopotential measurement applications. This device offers a single input channel with a 24-bit resolution, enabling precise signal acquisition.

 

Key electrical specifications include an SPI interface for communication and a wide analog supply voltage range of 2.7V to 5.25V, with digital supplies ranging from 1.7V to 3.6V. It boasts low power consumption of 335 µW/channel, making it suitable for portable devices. The input-referred noise is as low as 8 µV PP with a 150-Hz bandwidth and a gain of 6, complemented by a low input bias current of 200 pA.

 

This AFE supports data rates from 125 SPS up to 8 kSPS and offers a high Common Mode Rejection Ratio (CMRR) of 120 dB. Programmable gain options include 1, 2, 3, 4, 6, 8, or 12. The operating temperature range is -40°C to +85°C.

 

The ADS1291IRSMR is available in a 32-VQFN (4x4 mm) package and is designed for surface mounting. It includes built-in features such as a right leg drive amplifier, lead-off detection, and test signals, further simplifying system design for medical and fitness applications.
