7 Detailed Description
7.1 Overview
The LMV34x devices are precision operational amplifiers with CMOS inputs for very low input bias current. Output is rail-to-rail and input common-mode includes ground. LMV341 has a shutdown mode for very low supply current.
7.2 Functional Block Diagram
7.3 Feature Description
7.3.1 PMOS Input Stage
PMOS Input Stage supports a lower input range that includes ground. Upper range limit is V+ – 1 V.
7.3.2 CMOS Output Stage
The CMOS drain output topology allows rail-to-rail output swing.
7.3.3 Shutdown
LMV341 includes a shutdown pin. During shutdown, ICC is nearly zero and the output becomes high impedance. The typical turnon time coming out of shutdown is 5 µs.
7.4 Device Functional Modes
The LMV34x devices have two modes of operation:
- Normal operation when SHDN pin is at V+ level or the SHDN pin is not present
- Shutdown mode when SHDN is at GND level; ICC is very low and output is high impedance.
