OPA4313 - Texas Instruments

OPA4313 1.8-V CMOS OPERATIONAL AMPLIFIER

The OPA313 family of single-, dual-, and quadchannel op amps represents a new generation of lowcost, general purpose, micro-power operational amplifiers. Featuring rail-to-rail input and output swings, and low quiescent current (50 μA, typ) combined with a wide bandwidth of 1 MHz and very low noise (25 nV/√Hz at 1 kHz) makes this family very attractive for a.
