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) 100dB typ.
(2) Power supply fluctuation rejection ratio (PSRR1.1kHz) 80dB typ.
(3) Operating power supply voltage range +3 ~ +24V
(4) Consumption current 150µA typ.
(5) Voltage gain 50/100 times switching
(6) Input equivalent offset voltage ±0.5mV
(7) Current detection High/Low switching
(8) Single type

APPLICATIONs
(1) Notebook PCs
(2) PDA
