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)
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.
