The OPA313 family of single-, dual-, and quad-channel op amps represents a new generation of low-
cost, 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 variety of battery-powered applications that require a good balance between cost and performance. The low input bias current supports those op amps to be used in applications with megaohm source impedances.
