LINEAR INTEGRATED CIRCUIT
SINGLE GENERAL PURPOSE,
LOW VOLTAGE, RAIL-TO-RAIL
OUTPUT OPERATIONAL
AMPLIFIER
DESCRIPTION
The UTC LV321 is a single op amp with low supply current and
low voltage (2.7-5.5V) well economic consideration. It brings nice
performance and to low voltage, low power systems. With a 1MHz
unity-gain frequency, The UTC LV321 has a guaranteed 1 V/µs slew
rate and low supply current. It provides heavy rail-to-rail (R-to-R)
output swing loads and the input common-mode voltage range
including ground. Besides, it is also capable for comfortably driving
large capacitive loads.
The UTC LV321 has bipolar input and CMOS output for
improved noise performance and higher output current drive. It’s the
most cost effective solution for the applications where low voltage
operation, space saving and low price are required.
FEATURES
* 2.7V and 5V Performance Guaranteed
* No Crossover Distortion
* 130µA Low Supply Current
* Rail-to-Rail Output Swing @10kΩ Load: V+ -10mV
V- +65mV
* VCM From -0.2V to V+ -0.8V

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Shorting output to V+ will adversely affect reliability
3. Shorting output to V- will adversely affect reliability
