OP293FS

高精度，微功耗运算放大器 Precision, Micropower Operational Amplifiers

GENERAL DESCRIPTION

The OP193/OP293 are single-supply operational amplifiers that feature a combination of high precision, low supply current, and the ability to operate at low voltages. For high performance in single-supply systems, the input and output ranges include ground, and the outputs swing from the negative rail to within 600 mV of the positive supply. For low voltage operation, the OP193/OP293 can operate down to +1.7 V or ±0.85 V.
