AD8232 is an integrated front-end designed for signal conditioning of cardiac bioelectrical signals used in heart rate monitoring. It serves as a signal conditioning module for ECG and other bioelectrical measurement applications. The device extracts, amplifies, and filters weak bioelectrical signals in the presence of noise caused by motion or remote electrode placement. Its design enables easy signal capture by ultra-low-power analog-to-digital converters (ADCs) or embedded microcontrollers. The AD8232 incorporates a two-pole high-pass filter to suppress motion artifacts and electrode half-cell potentials. This filter is closely integrated with the instrumentation amplifier to provide single-stage high-gain and high-pass filtering, reducing space and cost requirements. A three-pole low-pass filter is implemented using an uncommitted operational amplifier to eliminate additional noise. Filter cutoff frequencies are user-selectable to accommodate various application needs. To enhance common-mode rejection of line frequency interference and other unwanted signals, the AD8232 includes an amplifier for driven lead configurations such as right-leg drive (RLD). The device features a fast recovery function that minimizes the long settling time typically associated with high-pass filters. In the event of abrupt signal changes, such as those caused by lead disconnection, the AD8232 automatically transitions to a higher filter cutoff frequency. This ensures rapid stabilization, allowing valid measurements to be obtained quickly after reconnection of electrodes. The AD8232 is specified for reliable performance across a temperature range of 0°C to 70°C, with an extended operating range from -40°C to +85°C.
