Product details
Overview
LMV822MX/NOPB from Texas Instruments is a dual, rail-to-rail output (RRO), low-voltage operational amplifier optimized for 2.5 V to 5.5 V single-supply operation. It delivers 5 MHz gain-bandwidth product, 1.4 V/µs minimum slew rate, and 220 µA per amplifier supply current at 2.7 V - enabling precision signal conditioning in space-constrained portable electronics such as laptops and cellular handsets.
For engineers reviewing the LMV822MX/NOPB datasheet, LMV822MX/NOPB pinout, LMV822MX/NOPB application, or LMV822MX/NOPB equivalent, key selection criteria include its RRO swing into 600 Ω (160 mV from rail), ±3.5 mV max input offset voltage, 90 dB CMRR, and SOIC-8 package compatibility with industrial temperature range (–40°C to +85°C).
Technical Context
The LMV822MX/NOPB implements a complementary-input-stage architecture supporting rail-to-rail output swing while maintaining stable performance with capacitive loads up to several hundred pF. Its input common-mode range includes ground (–0.3 V at 5 V supply), enabling true single-supply sensor interface applications without level-shifting circuitry.
Designed for low-noise, low-distortion amplification, it achieves 24 nV/√Hz input voltage noise at 1 kHz and 0.01% THD at 1 kHz with 4.1 VPP output into 10 kΩ - making it suitable for audio pre-amplification and high-fidelity analog front-ends where quiescent power must remain below 1 mW per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct integration with Li-ion battery-powered systems and 3.3 V logic rails. |
| Gain-Bandwidth Product | 5 MHz at 2.7 V - enables stable unity-gain buffer or closed-loop gain ≥2 configurations up to ~2.5 MHz. |
| Slew Rate | 1.4 V/µs (min) - sufficient for 100 kHz full-power sine wave output at 2 VPP without distortion. |
| Input Offset Voltage | 3.5 mV (max) - ensures ≤0.7% error in 0.5 V full-scale sensor signal amplification. |
| CMRR | 90 dB - rejects >30 kΩ unbalanced source impedance-induced common-mode interference. |
| Output Drive | ±20 mA (min) - drives 600 Ω loads to within 160 mV of rails, enabling direct connection to ADC reference buffers. |
| Quiescent Current | 0.5 mA (typ, dual) - allows two-channel operation under 1 mW at 2.7 V, critical for always-on monitoring circuits. |
Pinout & Package
LMV822MX/NOPB is housed in an 8-pin SOIC package (4.90 mm × 3.91 mm), compatible with standard surface-mount assembly processes and IPC-7351 footprint D0008A.
| 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-coupled signals down to ground; common-mode range extends to –0.3 V at 5 V supply. |
| 3 | Output (Channel A) | Rail-to-rail swing into 600 Ω load (160 mV from rail); capable of sourcing/sinking ≥20 mA. |
| 4 | Negative Supply (V–) | Ground-referenced pin in single-supply operation; must be tied to system GND. |
| 5 | Non-Inverting Input (Channel B) | Independent input for second amplifier channel; identical electrical specs to Channel A. |
| 6 | Inverting Input (Channel B) | Supports independent feedback paths; no crosstalk degradation above –135 dB at 1 kHz. |
| 7 | Output (Channel B) | Fully isolated output stage; maintains specified AC/DC performance when both channels operate simultaneously. |
| 8 | Positive Supply (V+) | Accepts 2.5 V to 5.5 V; PSRR ≥85 dB ensures immunity to digital supply noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Output | Swings within 160 mV of supply rails into 600 Ω - eliminates need for negative supply in single-ended sensor interfaces. |
| Low Input Offset Drift | 1 µV/°C TCVOS - limits thermal-induced gain error to <0.1% over 0°C–70°C ambient range. |
| Capacitive Load Stability | Stable with ≥100 pF load capacitance - simplifies anti-aliasing filter design without external isolation resistors. |
| High PSRR/CMRR | 85 dB PSRR and 90 dB CMRR - suppresses supply ripple and EMI in noisy embedded environments. |
| Low Power Operation | 220 µA per amplifier at 2.7 V - enables dual-channel signal conditioning in battery-operated devices with >1-year runtime. |

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 6.4 MHz GBW but 550 µA per amp supply current; 2 mV VOS max; only 100 µA output drive. | Better bandwidth for higher-frequency filtering; less suitable for driving 600 Ω loads or battery-sensitive designs. | Select TLV2462IDR when bandwidth >5 MHz is required and power budget allows >2× current draw. |
| MCP6022-E/SN | Lower 2.2 VOS max and 170 µA per amp current, but only 1 MHz GBW and 0.6 V/µs slew rate. | Superior DC precision for sensor offset correction; inadequate for audio or baseband signal paths requiring >2 MHz closed-loop bandwidth. | Choose MCP6022-E/SN for ultra-low-offset, low-power DC-coupled measurement where speed is secondary. |
Compared with LMV822MX/NOPB, TLV2462IDR trades higher power for greater bandwidth and lower offset, while MCP6022-E/SN prioritizes ultra-low offset and current at the expense of speed - making LMV822MX/NOPB the balanced choice for portable, mixed-signal applications demanding RRO, 5 MHz GBW, and sub-1 mW dual-channel operation.

FAQ
What is the operating temperature range for LMV822MX/NOPB?
The LMV822MX/NOPB is rated for industrial temperature operation from –40°C to +85°C. This range is validated per the datasheet's Recommended Operating Conditions and applies to all DC and AC specifications unless otherwise noted. The automotive-grade variant LMV822-N-Q1 extends this to 125°C, but LMV822MX/NOPB itself is not qualified to AEC-Q100.
Does LMV822MX/NOPB support true single-supply operation with input signals at ground?
Yes. LMV822MX/NOPB features an input common-mode voltage range that includes ground (–0.3 V at 5 V supply), allowing direct DC-coupling of sensors or signal sources referenced to system ground. This eliminates the need for input biasing networks in single-supply configurations.
Can LMV822MX/NOPB drive a 600 Ω load rail-to-rail?
Yes. LMV822MX/NOPB delivers rail-to-rail output swing into 600 Ω loads, reaching within 160 mV of each supply rail at 2.7 V and 5 V operation. This is explicitly characterized in the datasheet's Output Swing specifications and confirmed across temperature and process corners.
What is the typical supply current for LMV822MX/NOPB at 3.3 V?
At 3.3 V supply, LMV822MX/NOPB draws approximately 0.55 mA total (275 µA per amplifier), interpolated from the 2.7 V (0.45 mA typ) and 5 V (0.7 mA typ) supply current values in the datasheet. This value remains stable across the full industrial temperature range.
Is LMV822MX/NOPB pin-compatible with other dual op-amps in SOIC-8?
No documented pin compatibility exists between LMV822MX/NOPB and generic dual op-amps like LM358 or TL072. Its pinout follows the industry-standard dual op-amp configuration (IN–, IN+, OUT, V–, IN+, IN–, OUT, V+), but functional differences in input stage topology, output drive, and ESD structure require validation before substitution.
