Ordering Information
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.
packages that reduce space on pc boards and portable
electronic devices.
