Texas Instruments LMV341IDBVRE4

Overview

LMV341IDBVRE4 from Texas Instruments is a single-channel, rail-to-rail output CMOS operational amplifier with active-low shutdown control, designed for low-voltage (2.7V–5.5V) battery-powered systems. It delivers 1 MHz gain bandwidth, 1 V/μs slew rate, 0.25 mV typical input offset voltage, and ultra-low 1 pA typical input bias current - enabling precision signal conditioning in space-constrained portable electronics.

For engineers reviewing the LMV341IDBVRE4 datasheet, LMV341IDBVRE4 pinout, LMV341IDBVRE4 application, or LMV341IDBVRE4 equivalent, key selection criteria include shutdown current (33 nA typ. at 5V), rail-to-rail output swing (≤30 mV from rails at 10 kΩ load), input common-mode range extending to ground, and SOT-23-6 package compatibility with high-density PCB layouts.

Technical Context

The LMV341IDBVRE4 employs a PMOS input stage enabling rail-to-ground input common-mode operation (–0.2 V to V+ – 1 V) and sub-picoampere input bias current. Its CMOS output stage supports true rail-to-rail swing with <30 mV headroom at 10 kΩ load across –40°C to 125°C.

Shutdown functionality is implemented via an active-low SHDN pin (Pin 5), reducing supply current to 33 nA (typ.) at 5V while placing the output in high-impedance state; turn-on time from shutdown is 5 μs (typ.), supporting rapid power cycling in energy-sensitive applications.

FAQ

What is the maximum supply voltage rating for LMV341IDBVRE4?

The absolute maximum supply voltage for LMV341IDBVRE4 is 5.5 V. Operation above this level risks permanent damage per the Absolute Maximum Ratings table. Recommended operating range is 2.5 V to 5.5 V, with stable performance verified at 2.7 V and 5 V in electrical characteristics tables. Always use a 0.1 μF ceramic bypass capacitor at the V+ pin to suppress transients.

Does LMV341IDBVRE4 support rail-to-rail input operation?

LMV341IDBVRE4 supports rail-to-rail *output* swing but not full rail-to-rail *input*. Its input common-mode range extends from –0.2 V to V+ – 1 V, meaning it accepts signals down to ground (enabling single-supply sensor interfacing) but cannot handle inputs within 1 V of V+. This is due to its PMOS input stage architecture, confirmed in Section 6.3.1 of the datasheet.

How does the shutdown function behave on LMV341IDBVRE4?

When the SHDN pin (Pin 5) is pulled low (≤0.2 V), LMV341IDBVRE4 enters shutdown mode with supply current reduced to 33 nA (typ. at 5 V). The output becomes high-impedance, isolating downstream circuitry. To exit shutdown, drive SHDN to ≥2.4 V (at 2.7 V supply) or ≥4.5 V (at 5 V supply); turn-on time is 5 μs (typ.), as measured from SHDN rising edge to valid output.

What is the thermal performance of LMV341IDBVRE4 in its SOT-23 package?

LMV341IDBVRE4 in the DBV (SOT-23-6) package has a junction-to-ambient thermal resistance (R_θJA) of 88.7°C/W. At 125°C maximum junction temperature and 25°C ambient, it can dissipate up to 1.13 W continuously. With typical 150 μA supply current at 5 V (0.75 mW), self-heating is negligible (<1°C rise), enabling reliable operation in sealed enclosures without heatsinking.

Can LMV341IDBVRE4 drive a 600 Ω audio load directly?

No - LMV341IDBVRE4 is not specified for 600 Ω loads. Its output short-circuit current is 85 mA (sourcing, 5 V), but THD+N testing is only characterized at RL = 600 Ω with AV = 1 and VI = 1 VPP, yielding 0.012% at 1 kHz. Driving 600 Ω continuously risks thermal overload and violates recommended operating conditions; use a dedicated audio line driver or buffer stage for such loads.
