A Product Line of Diodes Incorporated AZV321 SINGLE LOW VOLTAGE RAIL-TO-RAIL OUTPUT OPERATIONAL AMPLIFIER Description Pin Assignments The AZV321 is single low voltage (2.7V to 5.5V) operational amplifier KS/K Package which has rail-to-rail output swing capability. The input common-mode (SC-70-5/SOT-23-5) voltage range includes ground. The chip exhibits excellent speed- power ratio, achieving 1MHz of bandwidth and 1V/µs of slew rate with l ow supply current. IN+ 1 5 VCC The AZV321 is built with BiCMOS process. It has bipolar input and output stages for improved noise performance, low input offset and VEE 2 higher output current drive. The AZV321 is available in the package of SC-70-5, which is IN- 3 4 OUTPUT 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 Applications integrity. The AZV321 is also available in standard SOT-23-5 package.  Active Filters  Low Power, Low Voltage Applications Features (For V =5V and V =0V, Typical unless Otherwise  General Purpose Portable Devices CC EE Noted)  Cellular Phone, Cordless Phone  Battery-Powered Systems  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 V near to V +65mV OL EE  V : -0.1V to V -0.8V CM CC Functional Block Diagram AZV321 1 of 13 September 2013 Document number: DS36528 Rev. 2 - 0 www.diodes.com © Diodes Incorporated
