Product details
Overview
LMV602MMX/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 (typ), delivers 1 MHz gain bandwidth, 1 V/µs slew rate, and features 20 fA input bias current and 0.55 mV typical input offset voltage. It is used in portable instrumentation signal conditioning and sensor front-end buffering.
For engineers reviewing the LMV602MMX/NOPB datasheet, LMV602MMX/NOPB pinout, LMV602MMX/NOPB application, or LMV602MMX/NOPB equivalent, key selection criteria include ultra-low quiescent current at 2.7 V, rail-to-rail output swing, PMOS-input stage enabling high-impedance sensor interfacing, and guaranteed performance across −40°C to +125°C.
Technical Context
The LMV602MMX/NOPB implements a patented Class AB turnaround stage within a CMOS process, reducing quiescent current while preserving slew rate and open-loop gain. Its PMOS differential input pair enables rail-to-rail common-mode input range down to ground and supports ultra-low input bias current (20 fA typ).
This dual op-amp lacks shutdown functionality-unlike the single-channel LMV601-and is specified for stable operation with capacitive loads up to 1000 pF. It achieves 72° phase margin and 20 dB gain margin at 100 kΩ load with 200 pF capacitance, supporting robust unity-gain buffer and active filter designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct connection to single-cell Li-ion (3.0–4.2 V) and 3.3 V logic rails without regulation. |
| Quiescent Current per Amplifier | 100 µA (typ) at 2.7 V - enables multi-day operation in always-on sensor nodes powered by coin cells. |
| Gain Bandwidth Product | 1 MHz - sufficient for anti-aliasing filters, audio preamps, and DC-coupled sensor amplification up to ~100 kHz. |
| Slew Rate | 1 V/µs - ensures faithful reproduction of 100-kHz, 1-VPP signals without distortion in unity-gain configurations. |
| Input Bias Current | 20 fA (typ) - minimizes voltage error in high-impedance pH, photodiode, or piezoelectric sensor interfaces. |
| Input Offset Voltage | 0.55 mV (typ) at 2.7 V - yields <1.7 mV total error over −40°C to +125°C, suitable for precision 12-bit ADC front-ends. |
| Output Swing | Rail-to-rail - delivers >99% of supply range into 10 kΩ load, maximizing dynamic range in low-voltage data acquisition. |
Pinout & Package
LMV602MMX/NOPB is packaged in an 8-pin VSSOP (DGK) with body size 3.00 mm × 3.00 mm, optimized for high-density portable PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - drives external load; rail-to-rail capable; must not be shorted to V+ or V− to avoid reliability degradation. |
| 2 | –INA | Inverting input, Channel A - connects to feedback network or inverting gain configuration; high-impedance (fA-level leakage). |
| 3 | +INA | Noninverting input, Channel A - accepts high-Z sensor signals; common-mode range includes ground (0 V) at 2.7 V supply. |
| 4 | V– | Negative supply terminal - tied to GND in single-supply operation; serves as reference for output swing and input common-mode range. |
| 5 | +INB | Noninverting input, Channel B - independent of Channel A; enables dual-sensor readout or signal splitting without cross-talk. |
| 6 | –INB | Inverting input, Channel B - isolated input node; supports separate feedback paths for each amplifier channel. |
| 7 | OUTB | Amplifier B output - electrically isolated from OUTA; shares same V+ and V– rails but exhibits <−60 dB crosstalk at 100 kHz. |
| 8 | V+ | Positive supply terminal - accepts 2.7–5.5 V; internal ESD protection rated to ±2000 V HBM; requires local 0.1 µF ceramic decoupling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP602-I/SN | Higher quiescent current (150 µA), lower GBW (2.8 MHz), BJT input (1 pA IB), no guaranteed 125°C operation. | Better for higher-speed, moderate-precision applications where supply current is secondary to bandwidth. | Select MCP602-I/SN when >2 MHz GBW is required and extended temperature is not needed. |
| TLV2462IDR | Higher supply current (550 µA), rail-to-rail I/O, 6.4 MHz GBW, 1.6 V/µs slew rate, wider VCC range (2.7–6 V). | Preferred for higher-drive, faster-settling applications such as multiplexed sensor arrays or active filters requiring >1 MHz closed-loop bandwidth. | Choose TLV2462IDR when output drive strength (>15 mA) or faster settling (<1 µs) outweighs ultra-low power needs. |
Compared with MCP602-I/SN and TLV2462IDR, LMV602MMX/NOPB offers the lowest quiescent current in its class while retaining 1 MHz bandwidth and full industrial temperature support-making it optimal for energy-harvested or long-life battery systems where every microamp counts.

FAQ
What is the maximum capacitive load the LMV602MMX/NOPB can drive stably?
The LMV602MMX/NOPB is unconditionally stable driving up to 1000 pF with a 100 kΩ load, as verified in TI's datasheet Figure 25 and Figure 26. This eliminates the need for isolation resistors in capacitive-load applications like LCD bias buffers or DAC output stages. Stability is maintained across −40°C to +125°C and both 2.7 V and 5 V supplies.
Does the LMV602MMX/NOPB have a shutdown pin?
No, the LMV602MMX/NOPB does not include a shutdown pin. Shutdown functionality is exclusive to the LMV601 (single-channel variant). The LMV602MMX/NOPB is a dual op-amp with fixed operation-both channels remain active whenever V+ and V– are powered. For power-gated designs, external FET control of the supply rail is required.
What is the input common-mode voltage range for the LMV602MMX/NOPB at 2.7 V supply?
At 2.7 V supply, the LMV602MMX/NOPB supports an input common-mode voltage range from 0 V (ground) to 1.7 V, as specified in Section 6.5 of the datasheet. This rail-to-ground capability stems from its PMOS input stage and enables direct interfacing with sensors referenced to system ground, such as thermistors or bridge circuits.
Can the LMV602MMX/NOPB operate from a single 3.3 V supply?
Yes, the LMV602MMX/NOPB is fully specified for single-supply operation from 2.7 V to 5.5 V. At 3.3 V, it delivers rail-to-rail output swing (within 30 mV of each rail into 10 kΩ), 100 µA quiescent current per amplifier, and maintains 1 MHz GBW and 72° phase margin-making it ideal for 3.3 V microcontroller-based sensor nodes and portable equipment.
How does the LMV602MMX/NOPB compare to the LMV601 in terms of input offset voltage?
The LMV602MMX/NOPB has a typical input offset voltage of 0.55 mV at 2.7 V (vs. 0.25 mV for the LMV601), as stated in Section 6.5 of the datasheet. This reflects the design trade-off for dual-channel integration: slightly higher VOS but identical architecture, noise, and bias current. Both parts share the same CMOS process and Class AB core, ensuring consistent low-power behavior across the LMV60x family.
