AD8232 is a fully integrated single-lead heart rate monitor front end with features such as low supply current, high common-mode rejection ratio, adjustable high-pass and low-pass filters.
The AD8232 is an integrated signal conditioning block specifically designed for ECG and other biopotential measurement applications. It extracts, amplifies, and filters small signals in noisy conditions, enabling ultra-low power analog-to-digital converters or embedded microcontrollers to acquire the output easily.
Key features include a fully integrated single-lead front end with low supply current (170 µA typical), high common-mode rejection ratio (80 dB dc to 60 Hz), and support for two or three electrode configurations. The device includes an uncommitted op amp, adjustable filters, and an internal RFI filter within a 20-lead LFCSP package.
