APX321/APX358/APX324 LOW VOLTAGE, RAIL-TO-RAIL INPUT AND OUTPUT SINGLE/DUAL/QUAD OPERATIONAL AMPLIFIERS General Description Features + (For V • • • • • • • • • • - 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 =5V and V =0V typical unless otherwise noted) Guaranteed 2.7V and 5V performance Crossover distortion eliminated Operating temperature range (-40°C to +85°C) Gain-bandwidth 1 MHz Low supply current • APX321 110 µA Typ • APX358 190 µA Typ • APX324 340 µA Typ Rail-to-rail output swing @ 10 kΩ + • V -10 mV • V +10 mV + Input Common Mode Voltage Range (0 to V -0.2V) Manufactured in standard CMOS process SOT353, SOT25, MSOP-8L, SOP-8L and TSSOP-14L: Available in “Green” Molding Compound (No Br, Sb) Lead-free Finish / RoHS Compliant (Note 4) packages that reduce space on pc boards and portable electronic devices.
