15 / 42 page  6 Detailed Description 6.1 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. 6.2 Functional Block Diagram 6.3 Feature Description 6.3.1 PMOS Input Stage PMOS Input Stage supports a lower input range that includes ground. Upper range limit is V+ – 1V. 6.3.2 CMOS Output Stage The CMOS drain output topology allows rail-to-rail output swing. 6.3.3 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 5µs. 6.4 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. www.ti.com LMV341, LMV342, LMV344 SLOS447J – SEPTEMBER 2004 – REVISED JUNE 2025 Copyright © 2025 Texas Instruments Incorporated Submit Document Feedback 15 Product Folder Links: LMV341 LMV342 LMV344 |
