MM1366

MITSUMI Quad Differential Amp MM1366 . U Monolithic IC MM1366 4 t e e h S Outline a at .D w w Features w Quad Differential co Amp m This IC is an audio quad differential amp with 4 channels - 2-input and 2-output. A 50kHz LPF is built in, doing away with the need for external capacitors and resistors and simplifying the design process. 1. CMRR 60dB typ. 2. PSRR1 f = 100Hz 80dB typ. 3. Operating voltage 4 ~ 6V 4. Consumption current 1.5mA typ. 5. Input impedance 47 kΩ typ. 6. Maximum output voltage (when RL = 10kΩ, THD = 10%) 1.25Vrms typ.
