Product Brief
SINGLE LOW VOLTAGE RAIL-TO-RAIL OUTPUT OPERATIONAL AMPLIFIER
AZV321
Description
Parametric Table
The AZV321 is single low voltage (2.7-5.5V) op amp
which has rail-to-rail output swing capability. The input
common-mode voltage range includes ground. The
chip exhibits excellent speed-power ratio, achieving
1MHz of bandwidth and 1V/µs of slew rate with low sup-
ply current.

The AZV321 is built with BiCMOS process. It has bipolar
input and output stages for improved noise performance,
low input offset and higher output current drive.

AZV321 is available in the package of SC70-5, which is
approximately half the size of SOT-23-5. The small
package saves space on pc boards, and enables the
design of small portable electronic devices. It also
allows the designer to place the device closer to the sig-
nal source to reduce noise pickup and increase signal
integrity.
