ed in portable electronic sphygmomanometer. It uses precision thick film ceramic chip and nylon plastic package with high linearity, low noise and stress of the outside world of small features; the internal calibration and temperature compensation to improve the measurement accuracy, stability and repeatability, in full scale, accuracy of 1%, the zero offset is not greater than 300 V.MAX4472 MAXIMs a four integrated low-power operational amplifier amplifier chip. The system integrated operational amplifier A constant current source connected to provide a constant current of a pressure sensor, and the op amp op amp B C, D constitute a differential amplifier input, single-ended output amplifier circuit, direct input ADC0 DC component of blood pressure monitoring.
