Quad Differential Amp
Monolithic IC MM1366
Outline
This IC is a 0dB gain amp with 4 channels of built-in differential input and differential output. It has powerful
noise removal at common mode level.
Features
(1) S/N can be improved for common mode noise on internal and external signal transmission due to
differential input/output.
(2) CMRR (common mode rejection ratio):
(3) PSRR (power supply rejection ratio):
(4) Consumption current
60 dB typ.
80 dB typ.
1.5mA typ.
Package
TSOP-20A
Applications
(1) Notebook PC audio

Application Circuit
Note 1 : This is 0dB defferential amp that have plus and minus pin at input and output.
(The condition of measuring gain is single input and output.)
Note 2 : The gain is 6dB at typical application circuit.
Note 3 : When connect A amplifier 2 and B Amplifier 3, improve for distortion rate from
THD1=-70dB to THD2=-75dB. (when +OUT3 output-10dB voltage)
