Product details
Overview
LMV601MGX/NOPB from Texas Instruments is a single-channel, rail-to-rail output operational amplifier optimized for low-voltage, battery-powered systems. It delivers 1 MHz gain bandwidth, 1 V/µs slew rate, and ultra-low 100 µA supply current at 2.7 V, with an active shutdown mode reducing current to 45 pA - enabling use in portable medical sensors and precision supply monitoring circuits.
For engineers reviewing the LMV601MGX/NOPB datasheet, LMV601MGX/NOPB pinout, LMV601MGX/NOPB application, or LMV601MGX/NOPB equivalent, key selection criteria include shutdown timing (5 µs turnon), input bias current (20 fA), rail-to-rail output swing (within 30 mV of rails), and SC70-6 package footprint compatibility with space-constrained PCB layouts.
Technical Context
The LMV601MGX/NOPB employs a PMOS input stage enabling 20 fA typical input bias current and rail-to-rail input common-mode range down to ground. Its patented Class AB turnaround stage achieves low quiescent current without sacrificing slew rate or open-loop gain.
Shutdown functionality is implemented via an 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 operates across −40°C to +125°C and supports single-supply voltages from 2.7 V to 5.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct integration into Li-ion (3.0–4.2 V) and 3.3-V logic systems without level-shifting. |
| Gain Bandwidth Product | 1 MHz - supports stable unity-gain buffer and low-frequency filtering (e.g., anti-aliasing up to ~100 kHz). |
| Supply Current (Active) | 100 µA per amplifier - allows >1-year operation on a 220 mAh coin cell in duty-cycled sensor nodes. |
| Shutdown Current | 45 pA typical - reduces standby power to negligible levels in always-on monitoring applications. |
| Input Bias Current | 20 fA - minimizes voltage error in high-impedance pH, photodiode, or thermistor interfaces. |
| Input Offset Voltage | 0.25 mV (typ.) - ensures ≤2.5 mV error in 10× gain signal chains without trimming. |
| Output Swing | Within 30 mV of rails (RL = 10 kΩ) - preserves dynamic range in 2.7-V single-supply data acquisition. |
Pinout & Package
LMV601MGX/NOPB is housed in a 6-pin SC70 package (2.00 mm × 1.25 mm), optimized for ultra-compact portable designs. Pinout is validated per TI SNOSC70C Rev C datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: +IN | Noninverting input | Accepts signals down to GND; supports single-supply sensor interfacing with no level shift. |
| 2: GND | Ground reference | Primary return path for supply and signal currents; must be low-impedance for noise immunity. |
| 3: –IN | Inverting input | Used for closed-loop configurations (e.g., transimpedance, difference amplification). |
| 4: OUT | Amplifier output | Rail-to-rail capable; tri-stated during shutdown to prevent loading downstream circuitry. |
| 5: SHDN | Active-low shutdown control | Pull low to disable; must not float - requires pullup or MCU GPIO drive for deterministic operation. |
| 6: V+ | Positive supply input | Accepts 2.7–5.5 V; decoupling capacitor (0.1 µF) required within 2 mm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input bias current | 20 fA enables accurate measurement of nanoamp-level sensor currents (e.g., ion-selective electrodes). |
| Fast shutdown recovery | 5 µs turnon time allows microsecond-scale wake-up in energy-harvesting systems. |
| Rail-to-rail output | Swings within 30 mV of V+ and GND at 2.7 V, maximizing ADC utilization in low-voltage systems. |
| Wide temperature range | −40°C to +125°C operation supports automotive cabin and industrial motor-control environments. |
| Low input voltage noise | 39–40 nV/√Hz at 1 kHz enables clean amplification of low-level audio and biopotential signals. |

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 pin; 100 µA supply current; 1 kHz input noise = 30 nV/√Hz. | Lacks power-gating capability; unsuitable for duty-cycled battery monitoring. | Select when shutdown is unnecessary and lower noise is prioritized over power control. |
| TLV6001IDCKR | Same SC70-6 package; 50 µA supply current; 0.5 mV max VOS; no guaranteed 125°C operation. | Lower quiescent current but narrower temp range limits use in under-hood automotive. | Select for cost-sensitive consumer devices where extended temperature is not required. |
Compared with MCP6001T-E/OT and TLV6001IDCKR, the LMV601MGX/NOPB uniquely combines guaranteed shutdown functionality, 125°C operation, and 20-fA input bias - making it the only option among the three for high-precision, wide-temp, battery-gated sensor nodes.

FAQ
What is the maximum allowable supply voltage for LMV601MGX/NOPB?
The absolute maximum supply voltage for LMV601MGX/NOPB is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Operation above 5.5 V risks permanent damage per TI's Absolute Maximum Ratings table. At 5.5 V, the device maintains full 125°C specification compliance and delivers optimal PSRR and CMRR performance.
Does LMV601MGX/NOPB support rail-to-rail input?
LMV601MGX/NOPB features rail-to-rail *output*, but its input common-mode range extends only to GND (not V+). Per datasheet Section 6.5, VCM is specified from 0 V to 1.7 V at 2.7 V supply - meaning the noninverting input can accept signals down to ground, but not up to V+. This makes it suitable for single-supply sensor buffers where the signal stays near GND.
How does the shutdown pin (SHDN) behave electrically on LMV601MGX/NOPB?
The SHDN pin on LMV601MGX/NOPB is active-low: pulling it below 0.8 V (max) at 2.7 V supply forces shutdown mode, reducing supply current to ≤1 µA. In shutdown, the output enters high-impedance state. The pin must never float - TI specifies a pullup resistor or driven GPIO is mandatory to avoid oscillation between modes.
Can LMV601MGX/NOPB drive a 600-Ω load reliably?
Yes, LMV601MGX/NOPB can source/sink ≥24 mA (per datasheet Section 6.5), supporting 600-Ω loads at ±2.5 V supply. However, total harmonic distortion rises to 0.017% at 1 kHz with 600-Ω load and 1 VPP output - acceptable for non-audio signal conditioning but not high-fidelity audio. For lowest THD, use ≥10-kΩ loads.
Is LMV601MGX/NOPB qualified for automotive applications?
LMV601MGX/NOPB is not AEC-Q200 qualified, though its −40°C to +125°C operating range meets many automotive under-hood temperature requirements. TI does not specify automotive-grade reliability testing (e.g., HTOL, ESD robustness beyond HBM ±2 kV) for this part. For automotive production, consult TI's automotive-qualified alternatives like TLV9001-Q1.
