Single lead heart rate monitoring front-end AD8232 is an integrated front end, suitable for letter on cardiac biological electrical signals Heart rate monitor, regulate. An application of integration is used for ECG and other bioelectricity signal conditioning module.This device is designed for the noise of a sports or remote electrodes placed under the condition of extraction, amplification and filter weak electrical signals.The design makes the ultra low power digital converter (ADC) or embedded microcontroller controller can easily capture the output signal. AD8232 adopts double pole high-pass filter to eliminate the motion artifacts and electrode half cell potential.The filter with the instrumentation amplifier structure tight coupling, which can realize single stage high gain and high pass filtering, thus saving the space and cost. AD8232 a operational amplifier without using constraint is used to create a three pole low-pass filter, eliminates the extra noise.Users can select all the filter cutoff frequency to meet the needs of different types of applications. In order to improve the system of line frequency interference and other adverse, common mode rejection performance AD8232 a built-in amplifier, is used to drive on the right side (RLD) driven by lead application. AD8232 contains a quick restore function, can reduce the high-pass filter was long established long tail phenomenon.If the voltage amplifier rail signal mutation (e.g., lead out of the situation), AD8232 will automatically adjust to higher filter cutoff state.This feature allow AD8232 can realize fast recovery, therefore after the electrode lead to connect to measure objects can achieve effective measurements as soon as possible. Guarantee the performance of the temperature range of 0 ℃ to 70 ℃, rated operating temperature range for – 40 ℃ to + 85 ℃. Application: Fitness and sports heart rate monitoring A portable ECG Remote health monitoring Game peripherals Biological electrical signal acquisition Pin number pin name description: 1 HPDRIVE qualcomm driver output side.HPDRIVE shall be connected to the first of the high-pass filter capacitance. AD8232 drive the pin to keep HPSENSE with reference voltage in the same level. 2 + IN instrumentation amplifier is input.+ IN usually connected to the left arm (LA) electrode. 3 – IN instrumentation amplifier negative input.- usually IN to connect to the right arm (RA) electrode. 4 RLDFB right leg drive feedback input.RLDFB is feedback pin of the right leg drive circuit. 5 RLD right leg drive output.Drive electrode (usually the right leg) shall be connected to the RLD pin. SW fast recovery switch pin 6.The pin should be connected to the output of the second high-pass filter. 7 OPAMP + in-phase operational amplifier input. 8 REFOUT reference voltage output buffers.Instrumentation amplifier output reference this potential. REFOUT should be used as a circuit at any point on the need of reference signal of the virtual land. 9 OPAMP – operational amplifier inverting input. 10 OUT operational amplifier output.This output provides completely regulate heart rate signal. OUT can be connected to the ADC input end. 11 LOD – lead off the comparator output.Under the mode of dc lead loss detection, when disconnected with – IN the electrode, LOD – at a high level, the opposite in the low level state.Lead in ac loss detection mode, the LOD – always in a state of low level. Lead off the comparator output.Under the mode of dc lead loss detection, when disconnected + IN electrode, LOD + at a high level, The opposite in the low level state.Under the mode of communication lead loss detection, when – or + IN disconnected IN electrode, LOD + at a high level, When the two electrodes are connected in a state of low level. LOD + 12 13 SDN shutoff control input.SDN drive to low level, can into low power off mode. 14 of AC/DC lead off mode control input.For DC lead off mode, AC/DC pin should be driven to a low level. Lead off mode for communication, AC/DC pin should be driven to high level. 15 FR fast recovery control input.FR driven to high level can make quick recovery mode;Otherwise, the driver should be to low level. 16 GND power supply. 17 + v power supply pins. 18 REFIN reference voltage input buffers.REFIN (high impedance input pin) can be used to set the benchmark voltage buffer level. 19 IAOUT instrumentation amplifier output pin. Qualcomm test input of 20 HPSENSE instrumentation amplifier. HPSENSE shall be connected to set the blocking circuit transition frequency of the R and C. EP bare bonding pad.Bare solder GND or they can keep the connection. On Dec 5, 2023 at 21:40:59 PST, seller added the following information:
