Texas Instruments LMV341IDBVRG4

Overview

LMV341IDBVRG4 from Texas Instruments is a single-channel, rail-to-rail output CMOS operational amplifier with active-low shutdown control, designed for ultra-low-power, low-voltage (2.7V–5.5V) applications. It delivers 1 MHz gain bandwidth, 1 V/μs slew rate, 0.25 mV typical input offset voltage, and 100 μA typical supply current - enabling precision signal conditioning in space-constrained battery-powered systems such as portable audio preamplifiers and battery monitoring circuits.

For engineers reviewing the LMV341IDBVRG4 datasheet, LMV341IDBVRG4 pinout, LMV341IDBVRG4 application, or LMV341IDBVRG4 equivalent, key selection criteria include its 1 pA typical input bias current, 5 μs typical turn-on time from shutdown, rail-to-rail output swing within 30 mV of rails (at 10 kΩ), shutdown current of 33 nA (typical at 5 V), and operation across –40°C to +125°C industrial temperature range.

Technical Context

The LMV341IDBVRG4 employs a PMOS input stage enabling rail-to-rail common-mode input range down to ground and up to V+ – 1 V, while its CMOS output stage ensures rail-to-rail output swing with <30 mV headroom at 10 kΩ load. Its shutdown function disables the amplifier and places the output in high-impedance state, reducing supply current to 33 nA (typical).

This device operates from a single 2.7V–5.5V supply, supports unity-gain stable operation, and maintains ≥70 dB large-signal voltage gain over full temperature range. Input referred voltage noise is 39–40 nV/√Hz at 1 kHz, and phase margin exceeds 70° under 100 kΩ load conditions - confirming robust stability in precision DC-coupled and low-frequency AC applications.

FAQ

What is the maximum supply voltage for LMV341IDBVRG4?

The absolute maximum supply voltage for LMV341IDBVRG4 is 5.5 V. Operation above this level risks permanent damage. The recommended operating range is 2.7 V to 5.5 V, with stable performance verified at both 3.3 V and 5 V nominal supplies. Always use a 0.1 μF ceramic bypass capacitor between V+ and GND, placed adjacent to the device.

Does LMV341IDBVRG4 support rail-to-rail input?

LMV341IDBVRG4 supports rail-to-rail *output* swing but has a limited input common-mode range: from –0.2 V to V+ – 1 V. This means the inputs operate down to ground (enabling single-supply use) but do not extend fully to V+. For true rail-to-rail input, consider alternatives like the TLV9001 or OPA316 - neither of which match LMV341IDBVRG4's 1 pA bias current.

How does the shutdown pin (SHDN) function on LMV341IDBVRG4?

The SHDN pin on LMV341IDBVRG4 is active-low: driving it ≤0.2 V places the device in shutdown mode, reducing supply current to 33 nA (typical at 5 V). Pulling SHDN ≥4.5 V (at 5 V supply) enables normal operation. During shutdown, the output enters high-impedance state - critical for multiplexed sensor systems where channel isolation is required.

What is the typical input offset voltage of LMV341IDBVRG4 and how does it vary with temperature?

LMV341IDBVRG4 has a typical input offset voltage of 0.25 mV at 25°C, with a maximum of 4.5 mV across –40°C to +125°C. Its average temperature coefficient is 1.7–1.9 μV/°C, meaning offset drift contributes <0.2 mV over a 100°C span - supporting stable DC-coupled gain stages in industrial environments without frequent calibration.

Can LMV341IDBVRG4 drive a 600 Ω load reliably?

LMV341IDBVRG4 is not optimized for 600 Ω loads: its output swing degrades significantly below 2 kΩ, and THD rises sharply (0.012% at 1 kHz with 600 Ω load). For audio line-driving or low-Z applications, TI recommends the OPA1678 or TPA6130A2. LMV341IDBVRG4 is best suited for high-impedance loads ≥10 kΩ, such as ADC drivers or sensor buffers.
