Product details
Overview
LMV602MA/NOPB from Texas Instruments is a dual, rail-to-rail output, low-power operational amplifier optimized for battery-powered and space-constrained systems. It operates from 2.7 V to 5.5 V, draws 100 µA per amplifier, delivers 1 MHz gain bandwidth, and features 20 fA input bias current and 0.55 mV typical input offset voltage - enabling precision sensing and signal conditioning in portable medical monitors and handheld test equipment.
For engineers reviewing the LMV602MA/NOPB datasheet, LMV602MA/NOPB pinout, LMV602MA/NOPB application, or LMV602MA/NOPB equivalent, key selection criteria include ultra-low supply current at 2.7 V, rail-to-rail output swing, industrial-plus temperature range (−40°C to 125°C), and compatibility with single-supply, low-voltage sensor front-ends and battery monitoring circuits.
Technical Context
The LMV602MA/NOPB uses a PMOS input stage to achieve 20 fA typical input bias current, making it suitable for high-impedance sensor interfaces such as pH electrodes and photodiode transimpedance amplifiers. Its Class AB turnaround stage enables 1 V/µs slew rate and 1 MHz GBW while maintaining only 100 µA quiescent current per channel.
It supports single-supply operation down to 2.7 V with rail-to-rail output swing (within 30 mV of rails at 10 kΩ load), common-mode input range extending to ground, and robust AC performance including 72° phase margin and 20 dB gain margin at 100 kΩ load - ensuring stable operation in active filters and precision buffers without external compensation.
Key Specifications

|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct interface with Li-ion battery (3.0–4.2 V) and 3.3-V logic without regulation |
| Quiescent Current (per amp) | 100 µA typical at 2.7 V - extends battery life in always-on sensor nodes and portable diagnostics |
| Gain Bandwidth Product | 1 MHz - supports stable unity-gain buffering and 2nd-order active filtering up to ~100 kHz |
| Input Bias Current | 20 fA typical - minimizes voltage error in >100-MΩ source impedances (e.g., piezoelectric sensors) |
| Input Offset Voltage | 0.55 mV typical (2.7 V, 25°C) - ensures ≤0.5% error in 100-mV full-scale biomedical signal chains |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - drives loads up to 32 mA; rail-to-rail capable; must not short to V+ or V− |
| 2 | –INA | Inverting input of Channel A - high-impedance node; sensitive to layout-induced leakage and noise |
| 3 | +INA | Noninverting input of Channel A - accepts common-mode voltages from ground to V+ − 0.2 V |
| 4 | V− | Negative supply terminal - connects to GND in single-supply configurations; decoupling required |
| 5 | +INB | Noninverting input of Channel B - electrically isolated from Channel A; shares same V− reference |
| 6 | –INB | Inverting input of Channel B - independent bias path; enables dual-channel differential or instrumentation topologies |
| 7 | OUTB | Amplifier B output - fully independent; supports simultaneous signal conditioning of two analog channels |
| 8 | V+ | Positive supply terminal - accepts 2.7–5.5 V; requires local 0.1-µF ceramic decoupling to GND |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP602-I/P | Higher supply current (150 µA), lower GBW (2.8 MHz), no guaranteed 2.7-V spec | Less suitable for ultra-low-power battery lifetime-critical designs; better for higher-speed filtering | Select when speed >1 MHz is required and 2.7-V operation is not mandatory |
| TLV2462IDR | Higher input bias current (1 pA), higher VOS (1.6 mV), wider supply range (2.7–6 V) | Lower precision in high-Z sensor paths; better for general-purpose buffering where offset is less critical | Select when broader supply flexibility and higher output drive (15 mA) outweigh ultra-low IB and VOS needs |
Compared with MCP602-I/P and TLV2462IDR, LMV602MA/NOPB provides the lowest input bias current and tightest VOS at 2.7 V, making it optimal for precision, low-power, single-supply sensor signal chains - whereas alternatives trade off bias current or offset for speed or drive strength.

FAQ
What is the minimum supply voltage for reliable operation of LMV602MA/NOPB?
The LMV602MA/NOPB is fully specified and guaranteed to operate from 2.7 V to 5.5 V. At 2.7 V, all key parameters-including 100 µA supply current, 1 MHz GBW, and rail-to-rail output swing-are ensured across the industrial temperature range. Operation below 2.7 V is not characterized and may result in degraded performance or instability.
Does LMV602MA/NOPB include a shutdown feature?
No, LMV602MA/NOPB does not include a shutdown pin. Only the LMV601 variant (single-channel) features an active-low SHDN pin. The LMV602MA/NOPB is a dual-channel amplifier without enable/disable control; power management must be handled externally via supply rail switching or system-level sleep modes.
Can LMV602MA/NOPB drive capacitive loads directly?
LMV602MA/NOPB is stable with capacitive loads up to 100 pF when driving a 100-kΩ load, as verified in TI's stability characterization. For loads >100 pF (e.g., coaxial cables or ADC input capacitance), a series resistor (≥200 Ω) between amplifier output and load is recommended to maintain phase margin and prevent peaking or oscillation.
What is the maximum output current capability of LMV602MA/NOPB?
LMV602MA/NOPB can source up to 32 mA and sink up to 24 mA per channel, as specified in the Electrical Characteristics tables. This is sufficient for driving 10-kΩ loads to rail with minimal droop and for interfacing directly with most SAR and delta-sigma ADC reference inputs without additional buffering.
Is LMV602MA/NOPB suitable for use with high-impedance pH electrodes?
Yes, LMV602MA/NOPB is well-suited for pH electrode interfaces due to its 20 fA typical input bias current, which minimizes voltage error across electrode impedances exceeding 100 MΩ. Combined with rail-to-rail output and low 0.55 mV VOS, it enables accurate, low-drift buffer stages in portable pH meters and water quality analyzers.
