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/s 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.

7. Shorting output to V+ will adversely affect reliability. 8. Shorting output to V- will adversely affect reliability. 9. Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not guaranteed on shipped production material. 10. All limits are guaranteed by testing or statistical analysis. 11. RL is connected to V-. The output voltage is 0.5V VO 4.5V. 12. All numbers are typical, and apply for packages soldered directly onto a PC board in still air. 13. Connected as voltage follower with 3V step input. Number specified is the slower of the positive and negative slew rates.
