[AK 2306/LV]
APPLICATION CIRCUIT EXAMPLE
Analog input circuit(AMPT0,1)
AK2306/LV has an op-amp at analog input of each channel. Each op-amp can be used as a gain adjustment.
Op-amp can be used as an inverting amplifier or differential input buffer with AMPRn as VREF buffer . Feedback
resistor must be 10k
ohm
or larger.
Single End buffer
Differential buffer
! Important Notice
Please use AMPRn as a AGND buffer to avoid a cross talk between TX and RX, channel1 and channel2
when TX input is composed as a differential input.
