Product details
Overview
LMV612MM/NOPB from Texas Instruments is a dual, rail-to-rail input/output, low-power operational amplifier optimized for 1.8-V single-supply operation in space-constrained portable electronics. It delivers 1.4-MHz gain bandwidth, 100-µA per-channel quiescent current, and output swing within 30 mV of rails into 2-kΩ load - enabling high-fidelity signal conditioning in battery-powered audio pre-amplifiers and supply current monitoring circuits.
For engineers reviewing the LMV612MM/NOPB datasheet, LMV612MM/NOPB pinout, LMV612MM/NOPB application, or LMV612MM/NOPB equivalent, key selection criteria include guaranteed 1.8-V operation, rail-to-rail I/O capability at ultra-low supply current, −40°C to +125°C temperature range, and VSSOP-8 package compatibility with area-sensitive PCB layouts.
Technical Context
The LMV612MM/NOPB implements a CMOS input stage with rail-to-rail common-mode input range extending 200 mV beyond both supply rails and rail-to-rail output drive capable of sourcing/sinking ≥8 mA while maintaining 30-mV headroom into 2-kΩ at 1.8 V. Its 1.4-MHz unity-gain bandwidth and 0.35-V/µs slew rate support stable closed-loop operation in unity-gain buffers and low-gain signal chains.
Designed for single-supply systems, it operates across 1.8 V to 5.5 V with specified performance at all three voltages (1.8 V, 2.7 V, 5 V), features 100-dB PSRR and ≥75-dB CMRR over full common-mode range, and maintains ≤4-mV input offset voltage with 5.5-µV/°C drift - ensuring precision in low-voltage sensor interfaces and battery voltage monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct connection to Li-ion, NiMH, and regulated 3.3-V/5-V rails without level shifting. |
| Gain Bandwidth Product | 1.4 MHz - enables stable unity-gain buffering and low-noise amplification up to ~100 kHz with minimal phase margin degradation. |
| Quiescent Current per Channel | 103 µA typical - allows dual-channel operation on microamp-level power budgets in always-on monitoring circuits. |
| Input Offset Voltage | ≤4 mV max - ensures <±1% error in 12-bit ADC front-ends with 2.5-V reference when used in non-inverting gain-of-2 configuration. |
| Output Swing (2-kΩ load) | Within 30 mV of rails at 1.8 V - preserves dynamic range in 1.8-V ADC drivers and audio line drivers without negative supply. |
| Input Common-Mode Range | V− − 0.2 V to V+ + 0.2 V - accepts ground-referenced inputs and supports high-side current sensing with single-supply biasing. |
| Operating Temperature | −40°C to +125°C - qualified for industrial and automotive cabin applications where ambient thermal stress exceeds consumer-grade limits. |
Pinout & Package
The LMV612MM/NOPB is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm, optimized for high-density portable PCBs. Its lead pitch is 0.65 mm, and thermal resistance is RθJA = 184.5°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load directly; rail-to-rail swing supports full 1.8-V signal range. |
| 2 | −IN A | Inverting input of Channel A - used in transimpedance, differential, or inverting gain configurations. |
| 3 | +IN A | Noninverting input of Channel A - accepts signals down to V− − 0.2 V, enabling ground-sensing applications. |
| 4 | V− | Negative supply terminal - tied to GND in single-supply mode; must be decoupled with 100-nF ceramic capacitor. |
| 5 | +IN B | Noninverting input of Channel B - electrically isolated from Channel A; supports dual independent signal paths. |
| 6 | −IN B | Inverting input of Channel B - shares no internal coupling with Channel A; amp-to-amp isolation >123 dB. |
| 7 | OUT B | Amplifier B output - independently configurable; identical AC/DC specs to OUT A under same conditions. |
| 8 | V+ | Positive supply terminal - accepts 1.8–5.5 V; requires local 100-nF bypass capacitor to minimize supply noise injection. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 1.8-V supply in single-ended sensor interfaces and eliminates need for level-shifting circuitry. |
| 100-µA per-channel quiescent current | Permits dual-channel amplification in energy-harvesting or coin-cell-powered devices with multi-year battery life. |
| Guaranteed 1.8-V operation | Validated across full temperature range (−40°C to +125°C), unlike many op-amps requiring ≥2.7 V minimum supply. |
| 80-mV rail-to-rail output swing into 600 Ω | Supports driving moderate loads such as ADC input networks or low-impedance audio lines without external buffers. |
| 123-dB amp-to-amp isolation | Prevents crosstalk between channels in dual-signal-path designs like stereo pre-amplifiers or dual-sensor conditioners. |

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 |
|---|---|---|---|
| TLV6002IDGKR | Lower 50-µA quiescent current but reduced 1-MHz GBW and 0.15-V/µs slew rate; VOS max = 3.5 mV. | Better suited for ultra-low-power wake-up circuits where bandwidth <500 kHz is acceptable. | Choose TLV6002IDGKR when system-level power budget is tighter than bandwidth requirement. |
| MCP6022-E/SN | Higher 100-µA IQ but wider 10-MHz GBW and 3.5-V/µs slew rate; VOS max = 2.5 mV; only rated to 85°C. | Preferred for higher-speed sensor interfaces (e.g., ultrasonic time-of-flight) requiring >1-MHz closed-loop bandwidth. | Select MCP6022-E/SN when extended temperature range is not required and faster settling is critical. |
Compared with TLV6002IDGKR and MCP6022-E/SN, the LMV612MM/NOPB uniquely balances 1.4-MHz bandwidth, 100-µA IQ, rail-to-rail I/O, and full industrial temperature rating - making it optimal for dual-channel, battery-operated systems needing both precision and thermal robustness.
