The ADS1291IPBS from Texas Instruments is a highly integrated, 24-bit Analog Front End (AFE) designed for applications requiring precise biopotential measurements, such as 1-lead ECG and ECG patches. This device offers a single input channel with a resolution of 24 bits, enabling detailed signal acquisition.
Key electrical specifications include an SPI interface for communication, analog supply voltages ranging from 2.7V to 5.25V, and digital supply voltages from 1.7V to 3.6V. It boasts low power consumption of 335 µW/channel, low input-referred noise of 8 µV PP, and a data rate that can be configured from 125 SPS to 8 kSPS. Programmable gain options from 1 to 12 are available, along with a CMRR of 120 dB.
The ADS1291IPBS is housed in a 32-lead TQFP package, suitable for surface mounting. It operates within an industrial temperature range of -40°C to +85°C, making it robust for various environmental conditions. The device also includes built-in features like a right leg drive amplifier, lead-off detection, and test signals, simplifying system design.
