Product details
Overview
LMV822MMX from Texas Instruments is a dual, rail-to-rail output (RRO), low-voltage operational amplifier optimized for battery-powered portable electronics. It delivers 5 MHz gain-bandwidth product at 2.7 V supply, 1.4 V/µs slew rate, 3.5 mV max input offset voltage, and 220 µA per amplifier quiescent current - enabling precision signal conditioning in space-constrained cordless phones, laptops, and PDAs.
For engineers reviewing the LMV822MMX datasheet, LMV822MMX pinout, LMV822MMX application, or LMV822MMX equivalent, key selection criteria include its SOIC-8 package compatibility, −40°C to +85°C industrial temperature range, rail-to-rail output swing (160 mV from rail into 600 Ω), and AEC-Q100 non-automotive qualification status.
Technical Context
The LMV822MMX operates from single supplies as low as 2.5 V with input common-mode range extending to ground (−0.3 V at 5 V supply) and rail-to-rail output stage capable of sourcing/sinking ≥12 mA. Its 90 dB CMRR and 85 dB PSRR ensure stable performance in noisy mixed-signal environments.
Designed for unity-gain stability with capacitive loads, the device features 1 µV/°C input offset drift and 24 nV/√Hz input voltage noise at 1 kHz - supporting accurate DC-coupled amplification and low-distortion AC signal paths without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct connection to Li-ion, 3.3 V, and 5 V rails without regulation. |
| Gain-Bandwidth Product | 5 MHz at 2.7 V - enables stable unity-gain buffers and closed-loop amplifiers up to ~100 kHz with 2× gain. |
| Slew Rate | 1.4 V/µs (min) - sufficient for 100 kHz sine waves at 2 VPP without distortion. |
| Input Offset Voltage | 3.5 mV (max) - ensures ≤0.7% error in 500 mV full-scale sensor interfaces. |
| Quiescent Current | 0.45 mA (typ) for dual channel - allows two independent amplifiers in <1 mW total power budget at 2.7 V. |
| Rail-to-Rail Output | Swings within 160 mV of rails into 600 Ω - preserves dynamic range in low-voltage ADC driver applications. |
| Input Common-Mode Range | −0.3 V to 4.3 V at 5 V supply - accepts signals below ground and near positive rail for single-supply transducer interfacing. |
Pinout & Package
LMV822MMX is packaged in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. Thermal resistance RθJA is 132.6°C/W, supporting operation up to +85°C ambient without forced airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | High-impedance node for feedback network connection; bias current ≤100 nA enables high-Z sensor interfaces. |
| 2 | Non-Inverting Input (Channel A) | Accepts DC- or AC-coupled input signals; common-mode range includes ground for single-supply operation. |
| 3 | Output (Channel A) | Rail-to-rail capable stage delivering ≥12 mA sourcing/sinking into 600 Ω load. |
| 4 | V− (Ground) | Reference terminal for single-supply operation; must be connected to system ground plane for noise immunity. |
| 5 | Non-Inverting Input (Channel B) | Independent input for second amplifier channel; electrically isolated from Channel A with >135 dB isolation. |
| 6 | Inverting Input (Channel B) | Supports differential or inverting configurations; matched to Channel A for dual-channel instrumentation. |
| 7 | Output (Channel B) | Functionally identical to Pin 3; enables dual-path signal processing without cross-talk degradation. |
| 8 | V+ | Positive supply rail; accepts 2.5–5.5 V; decoupling capacitor (0.1 µF) required within 5 mm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range into 600 Ω loads - critical for driving SAR ADC inputs without level-shifting circuitry. |
| Low input offset drift | 1 µV/°C TCVOS - maintains accuracy across temperature in portable medical and environmental sensors. |
| Stable with capacitive loads | No external compensation needed for CL ≤ 100 pF - simplifies layout in compact PCBs with long traces or EMI filters. |
| High PSRR/CMRR | 85 dB PSRR and 90 dB CMRR - rejects power supply ripple and common-mode interference in battery-powered audio front-ends. |
| Low-noise operation | 24 nV/√Hz input voltage noise at 1 kHz - preserves SNR in microphone preamplifier and precision transducer stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Higher quiescent current (550 µA/channel), wider VOS range (2 mV typ vs. 1 mV typ for LMV822MMX), same SOIC-8 package. | Less suitable for sub-1 mW battery systems but offers higher drive strength (25 mA) and better AC performance (6.4 MHz GBW). | Select TLV2462IDR when output drive >20 mA or GBW >5 MHz is required; verify thermal dissipation at 85°C ambient. |
| MCP6022-I/SN | Lower supply current (180 µA/channel), lower VOS (2.5 mV max), but reduced GBW (10 MHz) and no AEC-Q100 variant. | Better for ultra-low-power sensor nodes; not qualified for automotive use where LMV822-N-Q1 would apply instead. | Choose MCP6022-I/SN for extended battery life in consumer wearables; confirm rail-to-rail output compliance with 600 Ω load. |
Compared with TLV2462IDR and MCP6022-I/SN, LMV822MMX provides optimal balance of low power (450 µA total), rail-to-rail output into 600 Ω, and proven stability with capacitive loads - making it preferred for cost-sensitive, space-constrained portable designs requiring predictable performance across 2.5–5.5 V.

FAQ
What is the operating temperature range for LMV822MMX?
The LMV822MMX is specified for industrial operation from −40°C to +85°C. This range is confirmed in Section 6.3 (Recommended Operating Conditions) of the TI SNOS032I datasheet. It is not rated for automotive-grade temperatures (−40°C to +125°C); that specification applies only to the LMV822-N-Q1 variant. LMV822MMX maintains all electrical parameters within datasheet limits across this full industrial range.
Does LMV822MMX support true rail-to-rail input?
No, LMV822MMX does not feature rail-to-rail input. Its input common-mode voltage range extends to −0.3 V (below ground) and up to 4.3 V at 5 V supply - including ground but not reaching V+. The device is explicitly characterized as rail-to-rail *output* (RRO), with output swing within 160 mV of either rail into 600 Ω. Input stage headroom requirements are documented in Section 6.7 (DC Electrical Characteristics).
Can LMV822MMX drive a 1000 pF capacitive load stably?
LMV822MMX is characterized for stable operation with capacitive loads up to 100 pF without external compensation (Section 8.3, "Do's and Don'ts"). Driving 1000 pF directly risks peaking or oscillation. For larger loads, TI recommends adding a series resistor (≥100 Ω) between the output and capacitance, or using the recommended RC isolation network shown in Figure 22–24 of the datasheet. Always verify phase margin via simulation or bench test when exceeding 100 pF.
What is the maximum output current capability of LMV822MMX?
LMV822MMX delivers ≥12 mA sourcing and ≥12 mA sinking current under typical conditions (Section 6.7, DC Electrical Characteristics at 2.7 V). At 5 V supply, it sustains ≥20 mA sourcing and ≥20 mA sinking (Section 6.10). These values are guaranteed minimums across temperature; actual capability may reach 45 mA sourcing at 5 V but degrades above 85°C ambient due to thermal limits. Continuous operation above 20 mA requires thermal derating per RθJA = 132.6°C/W.
Is LMV822MMX pin-compatible with other dual op amps in SOIC-8?
LMV822MMX uses the industry-standard SOIC-8 (D) pinout defined in TI's device documentation (Pin Configuration, Page 5), matching conventional dual op amp assignments: Pins 1–3 (Ch A), Pin 4 (V−), Pins 5–7 (Ch B), Pin 8 (V+). It is pin-compatible with TLV2462, MCP6022, and LM358 variants in SOIC-8 - provided the target part shares identical input/output polarity and supply pin locations. Always verify functional equivalence and electrical compatibility before substitution.
