General Description

The APX321/APX358/APX324 are low voltage (2.5V to 5.5V) single, dual and quad operational amplifiers. The APX321/APX358/APX324 are designed to effectively reduce cost and space at low voltage levels. These devices have the capability of rail-to-rail output swing and input common-mode voltage range. They can also achieve an efficient speed-to-power ratio, utilizing 1 MHz bandwidth and 1 V/µs slew rate at a low supply current. Reducing noise pickup and increasing signal integrity can be achieved by placing the device close to the signal source. The APX321 is available in 5-Pin SOT353/SOT25 packages that reduce space on pc boards and portable electronic devices. The APX324 is available in the TSSOP-14L package. The APX358 is available in the MSOP-8L and SOP-8L packages.
