Sense Current Amplifier
Monolithic IC MM1380
Outline
This IC improves on the previous sensor amp MM1089 (Dual). It is a single amp that allows current sensing
regardless of the IC power supply (VCC). Further, the common mode signal rejection ratio and power supply
fluctuation rejection ratio have been improved, and gain is switched between 50 and 100 times.
Features
(1) Common mode signal rejection ratio (CMRR1.1kHz)
(2) Power supply fluctuation rejection ratio (PSRR1.1kHz)
(3) Operating power supply voltage range
(4) Consumption current
100dB typ.

(6) Input equivalent offset voltage
(7) Current detection
High/Low switching
(8) Single type
