AD8232 is an integrated front-end suitable for signal conditioning of cardiac bioelectrical signals for heart rate monitoring. An integrated signal conditioning module for ECG and other bioelectrical measurement applications. The device is designed to extract, amplify, and filter weak bioelectrical signals in the presence of noise from motion or remote electrode placement. The design allows an ultra-low-power analog-to-digital converter (ADC) or embedded microcontroller to easily capture the output signal. The AD8232 uses a two-pole high-pass filter to motion artifacts and electrode half-cell potentials. The filter is tightly coupled to the inst entation amplifier structure to achieve single-stage high-gain and high-pass filtering, saving space and cost. The AD8232 uses an unconstrained op amp to create a three-pole low-pass filter that eliminates additional noise. Users can select the cutoff frequencies of all filters to meet the needs of different types of applications. To improve common-mode rejection of system line frequencies and other undesirable interference, the AD8232 includes an amplifier for driven lead applications such as right-side drive (RLD). The AD8232 includes a fast recovery feature that reduces the long settling tail of high-pass filters. If there is a signal change in the amplifier rail voltage (such as a lead disconnection condition), the AD8232 automatically adjust to a higher filter cutoff state. This feature allows the AD8232 to achieve fast recovery, so that valid measurement values can be obtained as soon as possible after the leads are connected to the electrodes of the measurement object. The rated temperature range for guaranteed performance is 0 to 70 , and the operating temperature range is -40 to +85 . material: plastic Color as shown Package Contents: 1 x Development board 1 x line Only the above package content, other products are not included.
