Product details
Overview
LMV602MM/NOPB from Texas Instruments is a dual, rail-to-rail output, low-power operational amplifier designed 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, and achieves 1 V/µs slew rate with 0.55 mV input offset voltage (typ) at 2.7 V - enabling precision signal conditioning in portable medical sensors and handheld instrumentation.
For engineers reviewing the LMV602MM/NOPB datasheet, LMV602MM/NOPB pinout, LMV602MM/NOPB application, or LMV602MM/NOPB equivalent, key selection criteria include its ultra-low 20 fA input bias current, −40°C to +125°C industrial-plus temperature range, rail-to-rail output swing within 30 mV of supply rails, and compatibility with single-supply 2.7-V systems requiring low quiescent power and high DC accuracy.
Technical Context
The LMV602MM/NOPB uses a PMOS input stage to achieve 20 fA typical input bias current, making it suitable for high-impedance sensor interfaces where leakage must be minimized. Its Class AB turnaround stage enables low quiescent current (100 µA per channel) without sacrificing slew rate (1 V/µs) or open-loop gain (>113 dB).
It supports rail-to-rail output operation down to 30 mV from V+ and V− at 10 kΩ load, with guaranteed performance across 2.7 V–5.5 V supply and −40°C to +125°C ambient. Input common-mode range extends to ground, and PSRR (82 dB) and CMRR (80 dB) remain stable over supply and temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct interface with Li-ion, 3.3-V, and 5-V logic rails without level-shifting. |
| Quiescent Current (per amp) | 100 µA (typ) - allows continuous operation in always-on battery monitoring or sensor front-ends for multi-year runtime. |
| Gain Bandwidth Product | 1 MHz - supports stable unity-gain buffering and low-frequency filtering (e.g., anti-aliasing up to ~100 kHz). |
| Input Offset Voltage | 0.55 mV (typ, 2.7 V) - ensures <±1 LSB error in 12-bit ADC driver applications with 2.048-V reference. |
| Slew Rate | 1 V/µs - sufficient for settling 1-V step in <1.5 µs with <0.1% error, meeting requirements of portable data loggers. |
| Input Bias Current | 20 fA (typ) - minimizes voltage error in photodiode transimpedance amplifiers with >1 GΩ feedback resistors. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive modules, industrial PLC I/O, and outdoor IoT edge nodes. |
Pinout & Package
LMV602MM/NOPB is packaged in an 8-pin VSSOP (DGK) with nominal body size 3.00 mm × 3.00 mm, optimized for high-density PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA (Pin 1) | Output, Channel A | Rail-to-rail output capable of sourcing/sinking 32 mA; must not be shorted to V+ or V− to avoid reliability degradation. |
| –INA (Pin 2) | Inverting Input, Channel A | High-impedance PMOS node; input bias current ≤20 fA enables use with megaohm-level source impedances. |
| +INA (Pin 3) | Noninverting Input, Channel A | Common-mode range includes ground; supports single-supply operation with AC-coupled or DC-biased inputs. |
| V– (Pin 4) | Negative Supply | Ground reference for single-supply operation; tied to system GND in most portable designs. |
| +INB (Pin 5) | Noninverting Input, Channel B | Independent input for second signal path; no internal crosstalk coupling - 180 dB rejection at 1 kHz. |
| –INB (Pin 6) | Inverting Input, Channel B | Matched to Channel A inputs; supports dual-channel instrumentation amplifier configurations with matched gain. |
| OUTB (Pin 7) | Output, Channel B | Electrically isolated from OUTA; supports independent loading and output filtering per channel. |
| V+ (Pin 8) | Positive Supply | Accepts 2.7–5.5 V; PSRR of 82 dB suppresses noise from noisy switching regulators feeding this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input bias current | 20 fA typical - eliminates significant offset drift in high-Z pH electrode or thermopile sensor interfaces. |
| Rail-to-rail output swing | Within 30 mV of V+ and V− at 10 kΩ - maximizes dynamic range when driving SAR ADCs with 0–VREF input ranges. |
| Low-voltage operation | Functional from 2.7 V - enables direct connection to partially discharged Li-ion cells (≥2.7 V) without LDO dropout penalty. |
| Industrial-plus temperature range | −40°C to +125°C - meets AEC-Q100 Grade 2 requirements for under-dash automotive cabin modules. |
| Low input voltage noise | 39 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level signals from strain gauges or ECG electrodes. |

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/SN | Higher supply current (150 µA), lower GBW (2.8 MHz), BJT input (1 pA IB), no extended temp grade | Less suitable for ultra-low-power, high-impedance sensor nodes; better for higher-speed filtering | Select MCP602-I/SN only if >2-MHz bandwidth is required and 1-pA input bias is acceptable. |
| TLV2462IDR | Higher VOS (1.6 mV), higher noise (28 nV/√Hz), same 100 µA IQ, but wider supply (2.7–6 V) | Acceptable for cost-sensitive consumer audio line drivers, but insufficient for precision medical analog front-ends | Choose TLV2462IDR for non-critical general-purpose dual amplification where VOS tolerance >1 mV is allowed. |
Compared with MCP602-I/SN and TLV2462IDR, LMV602MM/NOPB provides the lowest input bias current (20 fA vs ≥1 pA) and tightest VOS (0.55 mV vs ≥1.6 mV), making it uniquely suited for high-accuracy, ultra-low-power sensor signal chains operating across extended temperature ranges.

FAQ
What is the maximum capacitive load the LMV602MM/NOPB can drive stably?
The LMV602MM/NOPB maintains stability with capacitive loads up to 1000 pF when configured as a unity-gain buffer with RL = 100 kΩ, as verified in Figure 24 and Figure 25 of the datasheet. For loads >100 pF, a series resistor (≥100 Ω) between the output and capacitor is recommended to ensure phase margin ≥72° across temperature.
Does the LMV602MM/NOPB have a shutdown pin?
No, the LMV602MM/NOPB does not include a shutdown pin. Shutdown functionality is exclusive to the LMV601 (single-channel variant). The LMV602MM/NOPB is a dual-channel amplifier with fixed operation - all pins are signal or supply terminals, and power control must be managed externally via the V+ rail.
Can the LMV602MM/NOPB operate from a single 2.7-V supply with rail-to-rail input capability?
The LMV602MM/NOPB supports rail-to-rail *output*, but its input common-mode range extends only to ground (V−) and up to 1.7 V at 2.7-V supply - not full rail-to-rail input. For true rail-to-rail input, consider TI's TLV2462 or OPA333 families; LMV602MM/NOPB remains optimal when input signals stay within 0–1.7 V at 2.7 V.
What is the thermal resistance (RθJA) of the LMV602MM/NOPB in its VSSOP package?
The LMV602MM/NOPB in the DGK (VSSOP-8) package has a junction-to-ambient thermal resistance (RθJA) of 178.3°C/W, as specified in Section 6.4 of the datasheet. This value assumes standard JEDEC 2-layer board conditions; actual board layout and copper area will affect real-world thermal performance.
Is the LMV602MM/NOPB suitable for driving ADC inputs directly?
Yes, the LMV602MM/NOPB is well-suited for driving SAR and delta-sigma ADC inputs. Its rail-to-rail output swing (within 30 mV of rails), low 0.55 mV VOS, and 39 nV/√Hz noise ensure minimal code errors and high effective resolution - especially when paired with 12- to 16-bit converters referenced to 2.048 V or 3.3 V.
