General Description
The LMV321 is a single channel, low cost, voltage feedback amplifier. The
LMV321 consumes only 130μA of supply current and is designed to operate
from a supply range of 2.7V to 5.5V (±1.35 to ±2.75). The input voltage
range extends 200mV below the negative rail and 800mV below the positive
rail.
The LMV321 is fabricated on a CMOS process. It offers 1MHz gain bandwidth
product and >1V/μs slew rate. The combination of low power, low supply
voltage operation, and rail-to-rail performance make the LMV321 well suited
for battery-powered systems. The LMV321 is packaged in the space saving
TSOT-5 package. TSOT-5 package is pin compatible with the SOT23-5
package.
