350Ω bridge measurement amplifier circuit composed of AD524
Source: InternetPublisher:elleny Keywords: amplifier circuit bridge AD Updated: 2020/05/02
Shown is a 350n bridge measurement amplifier circuit composed of AD 524 . IC 1 provides precision IO. OOV reference
voltage (RP fine-tuning output voltage, if the requirements are not particularly accurate, RP can be omitted) to the bridge sensor
(can be a pressure sensor, gas sensor, etc.). IC 2 is set as an amplifier with a gain of 100. After the signal is amplified,
it outputs an O-2V analog voltage from pin ⑨.
