SINGLE LOW VOLTAGE RAIL-TO-RAIL
OUTPUT OPERATIONAL AMPLIFIER
Description
The AZV321 is single low voltage (2.7V to 5.5V) operational amplifier
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.
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.
The AZV321 is available in the package of SC-70-5, 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.
The AZV321 is also available in standard SOT-23-5 package.
