Single-supply op-amp for battery-powered signal chains
The LMV611MG/NOPB is a single-channel general-purpose operational amplifier from Texas Instruments, designed for low-power, single-supply applications. It operates from 1.8 V to 5.5 V, making it a fit for battery-powered or 3.3 V/5 V sensor interfaces and ADC driver stages. With a gain-bandwidth product of 1.5 MHz and a slew rate of 0.42 V/µs, this op-amp handles audio-band signals and slow control loops without excess noise or oscillation. The rail-to-rail output stage swings within millivolts of the supply rails, preserving dynamic range in low-voltage designs.
Supply range, temperature grade, and output drive
Rated for the industrial temperature range of -40°C to 125°C, the LMV611MG/NOPB suits outdoor telecom, automotive cabin, and factory-floor sensor modules that see wide thermal swings. The 116 µA supply current keeps the quiescent draw low in always-on monitoring circuits. Each output can source or sink up to 100 mA, enough to drive a small relay, LED indicator, or the input of a downstream ADC. Input bias current is 14 nA typical, negligible for most divider networks but worth noting for high-impedance sources above 100 kΩ. Input offset voltage is 1 mV typical, which sets the DC accuracy floor for the signal chain. For a gain of 10, the output offset contribution is 10 mV before any trimming.
SC-70-5 package and PCB integration
Housed in a 5-lead SC-70-5 (SOT-353) package, the LMV611MG/NOPB occupies about 2.0 mm × 2.1 mm of board area. The surface-mount footprint is standard for this body size, and the pinout matches the industry-common single op-amp layout. Supplied in Tape & Reel (TR) or Cut Tape (CT) options, the reel format suits automated pick-and-place assembly. Store the reels dry — the MSL rating for this package is typically Level 1, but verify the reel label for bake requirements before reflow.
