Description: Product Description:AD8232 module ECG/bioelectrical signal acquisition development module Arduino compatibleAD8232 is an integrated front-end designed for signal conditioning of cardiac bioelectrical signals for heart rate monitoring.An integrated signal conditioning module for ECG and other bioelectrical measurement applications. This device is designed to extract, amplify, and filter weak bioelectrical signals in the presence of noise generated by motion or remote electrical placement. This design enables power consumption analog-to-digital converters (ADCs) or embedded microcontrollers to easily collect output signals.AD8232 uses a dual point high pass filter to eliminate motion artifacts and electric half cell potential. This filter is closely coupled with the instrument amplifier structure, enabling single-stage high gain and high pass filtering, thereby saving space and cost.AD8232 uses an unconstrained operational amplifier to create a three-point low-pass filter, eliminating additional noise. Users can meet the needs of different types of applications by selecting the cutoff frequencies of all filters.For the common mode suppression performance of system line frequency and other adverse interferences, the AD8232 is equipped with an amplifier for right-hand drive (RLD) and other driven lead applications.The AD8232 includes a fast recovery feature that can reduce the long tail phenomenon of high pass filters. If there is a signal mutation in the amplifier rail voltage (such as lead detachment), AD8232 will automatically adjust to a higher filter cutoff state. This feature allows AD8232 to achieve rapid recovery, allowing for effective measurement values to be obtained as soon as the lead is connected to the electrical measurement object.The rated temperature range for ensuring performance is from 0 ℃ to 70 ℃, and the working temperature range is from -40 ℃ to+85 ℃.Product application:1. Fitness and exercise heart rate monitoring2. Portable ECG3. Remote health monitoring4. Game peripherals5. Collection of bioelectrical signalsPin, number, pin name, description:1. HPDRIVE: Qualcomm driver output terminal. HPDRIVE should be connected to a capacitor in a high pass filter. AD8232 drives this pin to maintain HPSENSE at the same level as the reference voltage.2. +IN: Positive input terminal of instrument amplifier+ IN is usually connected to the left arm (LA) for electrical purposes.3. IN: Negative input terminal of instrument amplifier. IN is usually connected to the right arm (RA) for electrical purposes.4. RLDFB: Right leg drive feedback input end. RLDFB is the feedback pin of the right leg drive circuit5. RLD: Right leg drive output terminal. The driving power (usually the right leg) should be connected to the RLD pin.6. SW: Quick recovery switch pin. The pin should be connected to the output of the second high pass filter.7. OPAMP+: Operational amplifier in phase input terminal.8. REFOUT: Reference voltage buffer output terminal. The output of the instrument amplifier refers to this potential. REFOUT should be used as a virtual ground for any point in the circuit that requires a reference signal.9. OPAMP: Inverted input terminal of operational amplifier.10. OUT: Output terminal of operational amplifier. This output provides a conditioned heart rate signal. OUT can be connected to the input of ADC.11. LOD: Output end of lead dropout comparator. In the DC lead detachment detection mode, when disconnected from the IN circuit, the LOD is in a high-level state, and vice versa, it is in a low-level state. In the communication lead dropout detection mode, LOD remains in a low level state. Lead detachment comparator output end. In the DC lead detachment detection mode, when the+IN is disconnected, the LOD+is in a high-level state, and vice versa, it is in a low-level state. In the communication lead detachment detection mode, when IN or+IN are disconnected, LOD+is in a high-level state, and when both are connected, it is in a low-level state.12. LOD+13. SDN: Turn off control input terminal. Drive the SDN to a low level to enter low-power shutdown mode.14. AC/DC: Lead dropout mode control input terminal. For the DC lead dropout mode, the AC/DC pin should be driven to a low level. For the AC lead dropout mode, the AC/DC pin should be driven to a high level.15. FR: Fast recovery control input. Driving FR to a high level can enable fast recovery mode; Otherwise, it should be driven to a low level.16. GND: Power ground.17. +VS: Power pin.18. REFIN: Reference voltage buffer input terminal. REFIN (high impedance input pin) can be used to set the level of the reference voltage buffer.19. IAOUT: Instrument amplifier output pin.20. HPSENSE: High pass detection input of instrument amplifier. HPSENSE should be connected to the R and C nodes that set the transition frequency of the isolation circuit. EP bare solder pads. Exposed solder pads should be connected to GND or left unconnected.
