Low input bias current and wide bandwidth make it suitable for a variety of analog applications.+Four general-purpose operational amplifiers in one SOIC-14, the quad version of the LM358. Each runs from a single supply of 3 to 32 V (or a split supply) with an input range that includes the negative rail (ground), so it works in single-supply designs without a negative voltage. It is low power and inexpensive, which makes it the default op-amp for filters, buffers, summing amplifiers, and simple signal conditioning where precision is not critical. All four amplifiers share the V+ and GND pins.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | 1OUT | output | Output of op amp 1. Class-AB output stage capable of sourcing/sinking current; short-circuit protected to either supply rail. |+| 2 | 1IN- | input | Inverting (negative) input of op amp 1.
