BCD AZV321 Single low voltage rail-to-rail output operational amplifier Datasheet

Preliminary Datasheet
SINGLE LOW VOLTAGE RAIL-TO-RAIL OUTPUT OPERATIONAL AMPLIFIER
AZV321
General Description
Features
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 supply current.
(For VCC=5V and VEE=0V, Typical unless Otherwise
Noted)
· Guaranteed 2.7V to 5.5V Performance.
· No Crossover Distortion
· Gain-Bandwidth Product 1MHz
· Industrial Temperature Range: -40oC to +85oC
· Low Supply Current: 130µA
· Rail-to-Rail Output Swing under 10kΩ Load:
VOH up to VCC -10mV
VOL near to VEE +65mV
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
signal source to reduce noise pickup and increase signal integrity.
VCM: -0.2V to VCC-0.8V
Applications
