The AD8232 is an integrated front end for signal conditioning of cardiac bioelectric signals for heart rate monitoring.

An integrated signal conditioning module for ECG and other bioelectric measurement applications. The device is designed to extract, amplify, and filter weak bioelectric signals in the presence of noise generated by motion or remote electrode placement. The design allows ultra-low power analog-to-digital converters (ADCs) or embedded microcontrollers to easily acquire the output signal.

The AD8232 uses a two-pole high-pass filter to eliminate motion artifacts and electrode half-cell potentials. The filter is tightly coupled with the instrumentation amplifier structure to achieve single-stage high gain and high-pass filtering, saving space and cost.

The AD8232 uses an unconstrained operational amplifier to create a three-pole low-pass filter, eliminating additional noise. The user can select the cutoff frequency of all filters to meet the needs of different types of applications.

To improve the common-mode rejection of system line frequencies and other undesirable interference, the AD8232 has an internal amplifier for driven lead applications such as right-side drive (RLD).

The AD8232 includes a fast recovery feature that reduces the otherwise long settling tail of the high-pass filter. If a sudden signal change occurs in the amplifier rail voltage (such as a lead-off condition), the AD8232 automatically adjusts to a higher filter cutoff state. This feature allows the AD8232 to recover quickly, so valid measurements can be obtained as soon as possible after the leads are connected to the subject's electrodes.

Guaranteed performance is specified over the 0°C to 70°C temperature range and operates over the -40°C to +85°C temperature range.
