LCD Modules using PCF8574 8 bit I2C LCD Modules using PCF8574 8 bit I2C

high voltage op amp using UA741 The op-amp UA741 is wired to operate in three frequency ranges- high, medium and low. The circuit is designed such that the circuit produces +/-20 dB boost or attenuation for 50Hz,1KHz and 10Khz by varying POT’s R2. The maximum amplification for any of these bands at maximum supply voltage […]
