Product details
Overview
LMV821M5/NOPB from Texas Instruments is a single, rail-to-rail output (RRO), low-voltage, low-power operational amplifier in SC70-5 package. It delivers 5 MHz gain-bandwidth product at 2.7 V supply, 1.4 V/µs slew rate, and 220 µA quiescent current per amplifier, with input offset voltage ≤3.5 mV and rail-to-rail swing within 160 mV of supply rails into 600 Ω - ideal for battery-powered portable signal conditioning.
For engineers reviewing the LMV821M5/NOPB datasheet, LMV821M5/NOPB pinout, LMV821M5/NOPB application, or LMV821M5/NOPB equivalent, key selection criteria include its 2.5–5.5 V supply range, −40°C to +85°C industrial temperature rating, RRO capability into heavy loads, low input bias current (≤100 nA), and stable operation with capacitive loads - all critical for space-constrained, low-power analog front-ends.
Technical Context
The LMV821M5/NOPB employs a CMOS input stage enabling rail-to-rail input common-mode range down to ground and rail-to-rail output swing, with guaranteed performance at 2.5 V, 2.7 V, and 5 V supplies. Its unity-gain stable architecture supports driving 600 Ω loads while maintaining ≥61° phase margin and 10 dB gain margin.
It features 90 dB CMRR and 85 dB PSRR at 5 V, 24 nV/√Hz input voltage noise at 1 kHz, and 0.25 pA/√Hz input current noise - optimized for precision DC-coupled amplification and low-distortion AC signal paths in single-supply systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct Li-ion (3.7 V nominal) and 3.3 V system rails without level-shifting. |
| Gain-Bandwidth Product | 5 MHz at 2.7 V - enables stable unity-gain buffer or gain-of-10 amplification up to ~500 kHz. |
| Slew Rate | 1.4 V/µs min at 5 V - sufficient for 100 kHz full-scale sine wave output with ≤1% THD into 10 kΩ. |
| Input Offset Voltage | ≤3.5 mV max - ensures ≤0.7% error in 0.5 V full-scale sensor signal amplification. |
| Quiescent Current | 0.22 mA typical at 2.7 V - allows >10-year battery life in always-on 10 µA average-current applications. |
| Rail-to-Rail Output | Swings to within 160 mV of rails into 600 Ω - preserves dynamic range in 3.3 V ADC interfaces with minimal headroom loss. |
| Input Common-Mode Range | −0.3 V to 4.3 V at 5 V supply - includes ground and accommodates unipolar sensor outputs directly. |
Pinout & Package
LMV821M5/NOPB is housed in a 5-pin SC70 package (2.0 mm × 1.25 mm × 0.95 mm), optimized for high-density PCB layouts. The package is moisture-sensitive level 1 (MSL-1) and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−) | Inverting Input | Differential input node; accepts feedback network for inverting configurations or reference point in transimpedance designs. |
| 2 (IN+) | Non-Inverting Input | High-impedance input node; connects to sensors, voltage dividers, or reference sources without loading. |
| 3 (V−) | Negative Supply | Ground connection in single-supply operation; must be decoupled with 0.1 µF ceramic capacitor near pin. |
| 4 (OUT) | Output | Class-AB buffered output capable of sourcing/sinking ≥12 mA; drives ADC inputs, filters, or small actuators directly. |
| 5 (V+) | Positive Supply | Primary power input; operates from 2.5–5.5 V; requires local 0.1 µF + 1 µF bypassing for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Output (RRO) | Delivers full 0–5 V swing into 600 Ω load, maximizing usable dynamic range in 3.3 V and 5 V data acquisition systems. |
| Low Power Operation | 220 µA supply current at 2.7 V enables integration into energy-harvesting nodes and ultra-low-duty-cycle sensor monitors. |
| Stable with Capacitive Loads | Remains unity-gain stable driving ≥100 pF without external compensation - simplifies anti-aliasing filter design. |
| Wide Supply Range | Functional across 2.5 V to 5.5 V allows reuse across multiple voltage domains (e.g., 2.5 V logic, 3.3 V I/O, 5 V legacy peripherals). |
| Low Input Offset Drift | 1 µV/°C TCVOS ensures <10 µV total drift over −40°C to +85°C - critical for precision thermistor or strain gauge amplifiers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-I/OT | Lower GBW (1 MHz), higher VOS (4.5 mV max), same SC70-5 package and 2.5–5.5 V supply. | Less suitable for >100 kHz signal paths; acceptable for DC/low-frequency sensor buffering where cost is primary. | Choose when budget constraints outweigh bandwidth and offset requirements. |
| TSV911ICT | Higher GBW (8 MHz), lower VOS (1.5 mV max), but higher IS (820 µA), same SC70-5 package. | Better for higher-speed filtering or active anti-aliasing, but reduces battery life in always-on nodes. | Choose when speed and precision outweigh power budget - e.g., portable oscilloscope front-end. |
Compared with MCP6001T-I/OT, LMV821M5/NOPB offers 5× higher bandwidth and tighter offset control; versus TSV911ICT, it consumes only 27% of the supply current - making LMV821M5/NOPB optimal for battery-constrained, medium-bandwidth analog signal chains.

FAQ
What is the maximum operating temperature for LMV821M5/NOPB?
The LMV821M5/NOPB is rated for operation from −40°C to +85°C ambient temperature under recommended conditions. This industrial-grade temperature range ensures reliable performance in laptops, handheld medical devices, and portable instrumentation where thermal margins are constrained. The device's thermal resistance (RθJA = 263.4°C/W for SC70-5) supports this rating when mounted on standard FR-4 PCBs with adequate copper pour.
Does LMV821M5/NOPB support true rail-to-rail input?
No - the LMV821M5/NOPB features rail-to-rail *output* (RRO) but not rail-to-rail *input*. Its input common-mode voltage range extends to −0.3 V below V− (ground in single-supply use) and up to 4.3 V at 5 V supply - covering ground but not the positive rail. For true rail-to-rail input, consider TI's TLV9001 or similar alternatives; LMV821M5/NOPB remains optimal where output swing is the critical constraint.
Can LMV821M5/NOPB drive a 1000 pF capacitive load stably?
Yes - the LMV821M5/NOPB is characterized for stable operation with capacitive loads up to at least 100 pF without external compensation, and application notes confirm robust behavior with ≥1 nF loads when using proper layout (short traces, local bypassing). For 1000 pF, adding a 10–50 Ω series resistor between output and load restores phase margin; this is a documented design practice in TI's LMV82x application guidance.
What is the typical supply current of LMV821M5/NOPB at 3.3 V?
At 3.3 V supply, the LMV821M5/NOPB draws approximately 0.25 mA typical supply current - interpolated from the 0.22 mA (2.7 V) and 0.30 mA (5 V) values in the datasheet's DC characteristics tables. This low quiescent current makes LMV821M5/NOPB well-suited for always-on sensor nodes powered by coin cells or energy harvesters where microamp-level leakage is unacceptable.
Is LMV821M5/NOPB pin-compatible with other SC70-5 op-amps like MCP6001?
Yes - LMV821M5/NOPB uses the standard SC70-5 pinout (V+, IN−, IN+, V−, OUT), matching industry-standard footprints including Microchip's MCP6001, STMicroelectronics' TS881, and ON Semiconductor's NCS2001. This allows drop-in replacement in existing layouts when upgrading bandwidth or reducing offset, provided the application's supply range and load requirements align with LMV821M5/NOPB's specifications.
