Product details
Overview
LMV601MG/NOPB from Texas Instruments is a single-channel, rail-to-rail output operational amplifier optimized for low-voltage, ultra-low-power portable applications. It operates from 2.7 V to 5.5 V, draws only 100 µA quiescent current per amplifier, features 1 MHz gain bandwidth, 20 fA input bias current, and includes an active-low shutdown pin enabling 45 pA shutdown current - ideal for battery monitoring and supply current sensing in space-constrained handheld devices.
For engineers reviewing the LMV601MG/NOPB datasheet, LMV601MG/NOPB pinout, LMV601MG/NOPB application, or LMV601MG/NOPB equivalent, key selection considerations include its SC70-6 package footprint (2.00 mm × 1.25 mm), shutdown timing (5 µs turnon), rail-to-rail output swing (within 30 mV of rails at 2.7 V), and PMOS input stage enabling femtoampere-level bias current critical for high-impedance sensor interfaces.
Technical Context
The LMV601MG/NOPB employs a patented Class AB turnaround stage built on CMOS technology, replacing conventional folded cascode architectures to achieve lower quiescent current without sacrificing slew rate (1 V/µs) or open-loop gain. Its PMOS differential input pair enables ground-sensing capability and ensures input bias current remains stable across common-mode voltage (0–1.7 V at 2.7 V supply).
Shutdown functionality is implemented via a dedicated active-low SHDN pin (Pin 5), which places the output in high-impedance state and reduces supply current to ≤1 µA (typ. 45 pA). The device maintains guaranteed performance over −40°C to +125°C and supports single-supply operation down to 2.7 V with rail-to-rail output swing and 80 dB CMRR.
Key Specifications

|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct connection to Li-ion battery or 3.3 V logic rails without regulation |
| Quiescent Current | 100 µA (typ.) - enables >1-year battery life in always-on sensor monitoring circuits |
| Gain Bandwidth Product | 1 MHz - sufficient for anti-aliasing filters, audio preamps, and closed-loop gain ≤100 at DC–10 kHz |
| Input Bias Current | 20 fA (typ.) - minimizes voltage error in photodiode, pH sensor, or high-Z RC filter interfaces |
| Shutdown Current | 45 pA (typ.) - reduces power by 2.2 million× vs active mode, critical for intermittent wake-up systems |
| Turnon Time from Shutdown | 5 µs - allows rapid reactivation for burst-mode signal acquisition without latency penalty |
| Input Offset Voltage | 0.25 mV (typ.) - delivers <0.5% error in 12-bit ADC front-end applications with gain = 10 |
Pinout & Package
The LMV601MG/NOPB is housed in a 6-pin SC70 package (2.00 mm × 1.25 mm body size), optimized for PCB area-constrained portable electronics. Its compact footprint occupies ~25% of a standard SOIC-8 area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| +IN (Pin 1) | Noninverting input | High-impedance node accepting signals from 0 V to V+ − 1.7 V; compatible with ground-referenced sensors |
| −IN (Pin 3) | Inverting input | Accepts feedback or reference signals; matched input capacitance enables stable unity-gain buffer use |
| OUT (Pin 4) | Amplifier output | Rail-to-rail capable (within 30 mV of V+ or GND); drives ≥10 kΩ loads while maintaining linearity |
| SHDN (Pin 5) | Active-low enable | Pull ≤0.8 V to disable; pull ≥1.7 V (2.7 V supply) or ≥3.1 V (5 V supply) to activate; never float |
| V+ (Pin 6) | Positive supply | Single-supply input supporting 2.7–5.5 V; internal ESD protection rated ±2000 V HBM |

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 | No shutdown function; 100 µA IQ; 1 MHz GBW; SOT-23-5 package (no SHDN pin) | Suitable where continuous operation is required and PCB layout cannot accommodate shutdown control logic | Select when shutdown is unnecessary and cost sensitivity outweighs feature parity |
| TLV9001IDBVR | Includes shutdown; 60 µA IQ (lower); 1 MHz GBW; same SC70-6 footprint; rail-to-rail I/O | Better suited for ultra-low-power always-on monitoring where <60 µA IQ is mandatory | Prefer when minimizing active-mode current is critical and TI's LMV601MG/NOPB's higher VOS (0.25 mV vs 0.3 mV typ.) is acceptable |
Compared with MCP6001T-E/OT, LMV601MG/NOPB adds shutdown control and matches VOS but consumes slightly more active current; versus TLV9001IDBVR, it trades 40 µA lower IQ for tighter offset and proven robustness in extended temperature industrial use cases.

FAQ
What is the maximum operating temperature range for the LMV601MG/NOPB?
The LMV601MG/NOPB is specified to operate from −40°C to +125°C across its full electrical performance envelope. This industrial-plus temperature range enables reliable deployment in automotive cabin modules, industrial handheld testers, and outdoor IoT sensors without derating. All key parameters - including input offset voltage, CMRR, and supply current - are guaranteed across this range per TI's production test flow.
Does the LMV601MG/NOPB support true rail-to-rail input?
No, the LMV601MG/NOPB features rail-to-rail *output* but not rail-to-rail input. Its input common-mode voltage range extends from GND to (V+ − 1.7 V) at 2.7 V supply, and to (V+ − 1.0 V) at 5 V supply. The PMOS input stage allows the noninverting input to reach ground, making it suitable for single-supply sensor interfaces where the signal references GND, but it cannot accept inputs at the positive rail.
How does the shutdown pin (SHDN) behave electrically on the LMV601MG/NOPB?
The SHDN pin on the LMV601MG/NOPB is active-low: pulling it ≤0.8 V disables the amplifier, tri-stating the output and reducing supply current to ≤1 µA (typ. 45 pA); pulling it ≥1.7 V (at 2.7 V supply) or ≥3.1 V (at 5 V supply) enables normal operation. The pin must never be left floating - unconnected SHDN causes undefined behavior and potential oscillation between modes.
Can the LMV601MG/NOPB drive capacitive loads, and what is its stability limit?
Yes, the LMV601MG/NOPB is stable with capacitive loads up to 100 pF when configured as a unity-gain buffer, per TI's Figure 26 and 27. For loads >100 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended. Its phase margin remains ≥72° at 100 kΩ load and 200 pF capacitance, ensuring robust step response without peaking or ringing in typical sensor buffering applications.
What is the typical input voltage noise density of the LMV601MG/NOPB at 1 kHz?
The LMV601MG/NOPB exhibits a typical input-referred voltage noise density of 39 nV/√Hz at 1 kHz under 5 V supply conditions, and 40 nV/√Hz at 2.7 V. This value is confirmed in Section 6.6 of the datasheet and reflects its PMOS input architecture - slightly higher than BJT-input op-amps below 1 kHz but advantageous above due to lower 1/f noise corner and negligible current noise (0.001 pA/√Hz).
