Product details
Overview
LMV611MGX/NOPB from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It operates from 1.8 V to 5.5 V, delivers 1.4-MHz gain-bandwidth product, draws only 100 µA supply current per channel, and supports rail-to-rail output swing within 30 mV of either rail under 2-kΩ load - enabling precision signal conditioning in battery-powered audio pre-amplifiers and supply current monitoring circuits.
For engineers reviewing the LMV611MGX/NOPB datasheet, LMV611MGX/NOPB pinout, LMV611MGX/NOPB application, or LMV611MGX/NOPB equivalent, key selection criteria include its guaranteed 1.8-V operation, −40°C to +125°C industrial-plus temperature range, 4-mV max input offset voltage, rail-to-rail input common-mode range extending 200 mV beyond supplies, and SC70-5 package footprint for space-constrained portable designs.
Technical Context
The LMV611MGX/NOPB uses a CMOS input stage enabling ultra-low input bias current (15 nA typical) and rail-to-rail input common-mode voltage range (V– – 0.2 V to V+ + 0.2 V at 25°C). Its output stage employs complementary push-pull architecture to achieve 30-mV rail-to-rail swing into 2-kΩ loads at 1.8 V supply.
This op amp features stable unity-gain operation with 67° phase margin and 7 dB gain margin at 1.8 V, delivering 0.35 V/µs slew rate and 60-dB minimum CMRR over its full common-mode range - making it suitable for DC-coupled sensor interfaces and single-supply active filters where input headroom and output compliance are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - enables direct integration into Li-ion, coin-cell, and multi-rail embedded systems without level-shifting. |
| Gain-Bandwidth Product | 1.4 MHz - supports stable closed-loop operation up to ~100 kHz with gain ≥10, sufficient for anti-aliasing and audio-band filtering. |
| Quiescent Current | 100 µA per channel - allows continuous operation in always-on battery-monitoring circuits with multi-year runtime. |
| Input Offset Voltage | Max 4 mV - ensures ≤0.4% error in 1-V full-scale current-sense amplification without trimming. |
| Output Swing (2-kΩ) | Within 30 mV of rails at 1.8 V - preserves dynamic range in single-supply 1.8-V microcontroller ADC front-ends. |
| Input Common-Mode Range | V– – 0.2 V to V+ + 0.2 V at 25°C - accepts signals below ground or above supply, simplifying bipolar sensor interfacing. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive modules, industrial PLC I/O, and outdoor IoT edge nodes. |
Pinout & Package
LMV611MGX/NOPB is packaged in a 5-pin SC70 (2.00 mm × 1.25 mm) surface-mount package, optimized for high-density portable PCB layouts. The SC70 footprint occupies ~40% less area than comparable SOT-23-5 devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: +IN | Noninverting input | High-impedance CMOS node; accepts signals down to V– – 0.2 V for true rail-to-rail input operation. |
| 2: V– | Negative supply | Ground reference in single-supply configurations; must be connected to system GND or negative rail. |
| 3: –IN | Inverting input | High-impedance CMOS node; used for feedback networks and transimpedance configurations. |
| 4: OUTPUT | Amplifier output | Capable of sourcing/sinking ≥8 mA; swings within 30 mV of V– or V+ into 2-kΩ load at 1.8 V. |
| 5: V+ | Positive supply | Accepts 1.8–5.5 V; internal regulation ensures consistent performance across supply range. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-E/OT (Microchip) | Lower 100-kHz GBW; 6-µA IQ; same SC70-5 package; 2-mV max VOS. | Better for ultra-low-power sleep-mode monitoring; insufficient bandwidth for audio or fast current sensing. | Select when sub-10-µA supply current dominates over bandwidth or output drive requirements. |
| TSV611ICT (STMicroelectronics) | Same 1.4-MHz GBW; 115-µA IQ; 2.5-mV max VOS; requires 2.7-V min supply. | Not usable below 2.7 V; superior offset but incompatible with 1.8-V-only systems. | Choose only if system supply is ≥2.7 V and tighter offset tolerance (2.5 mV vs 4 mV) is required. |
Compared with MCP6001T-E/OT and TSV611ICT, LMV611MGX/NOPB uniquely balances 1.4-MHz bandwidth, 1.8-V operation, and 100-µA IQ in SC70-5 - making it the sole option among these three for battery-powered 1.8-V signal chains requiring both speed and efficiency.
