Product details
Overview
LMV824M/NOPB from Texas Instruments is a quad, rail-to-rail output (RRO), low-voltage (2.5 V to 5.5 V), low-power (1.0 mA typical total supply current) operational amplifier optimized for portable and space-constrained systems. It delivers 5 MHz gain-bandwidth product, 1.4 V/µs slew rate, and 3.5 mV max input offset voltage at 2.7 V supply - enabling precision signal conditioning in battery-powered audio, sensor interfaces, and analog front-ends.
For engineers reviewing the LMV824M/NOPB datasheet, LMV824M/NOPB pinout, LMV824M/NOPB application, or LMV824M/NOPB equivalent, this page provides verified specifications, SOIC-14 package details, real-world use cases in laptops and PCMCIA modems, and validated alternative op-amps with documented functional trade-offs.
Technical Context
The LMV824M/NOPB implements a CMOS-input, rail-to-rail output architecture with input common-mode range extending to ground (–0.3 V at 5 V supply) and output swing within 160 mV of rails under 600 Ω load. Its unity-gain stable design supports capacitive loads up to 100 pF without oscillation, and its 90 dB CMRR and 85 dB PSRR ensure robust performance in noisy single-supply environments.
It operates across –40°C to +85°C (industrial grade), with guaranteed DC specs at 2.5 V, 2.7 V, and 5 V supplies. The device features 24 nV/√Hz input voltage noise at 1 kHz and 0.25 pA/√Hz input current noise - balancing low power and signal fidelity for medium-bandwidth applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - enables direct operation from Li-ion (3.3 V), USB (5 V), or dual-cell alkaline (3 V) rails without regulation. |
| Gain-Bandwidth Product | 5 MHz at 2.7 V - supports stable closed-loop gain up to ~50 at 100 kHz for sensor amplification or active filtering. |
| Slew Rate | 1.4 V/µs min at 5 V - sufficient for 100 kHz full-scale sine waves up to ~2 VPP without distortion. |
| Input Offset Voltage | 3.5 mV max - ensures ≤0.7% error in 500 mV full-scale 12-bit ADC interfaces without trimming. |
| Rail-to-Rail Output | Swings to within 160 mV of rails into 600 Ω - maximizes dynamic range in 3.3 V or 5 V single-supply data acquisition. |
| Quiescent Current | 1.0 mA typical (250 µA per amplifier) - allows four-channel buffering in ultra-low-power wake-up circuits. |
| CMRR / PSRR | 90 dB / 85 dB - rejects supply ripple and common-mode interference in mixed-signal PCB layouts. |
Pinout & Package
LMV824M/NOPB is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package measuring 8.65 mm × 3.91 mm, with standard 1.27 mm pitch and surface-mount compatibility. This industrial-grade package supports reflow soldering and offers thermal resistance RθJA = 109.7°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 12 | Non-Inverting Input (+IN) | Four independent high-impedance (≥1012 Ω) inputs accepting signals down to ground level. |
| 2, 6, 10, 13 | Inverting Input (–IN) | Four independent high-impedance inputs for feedback or differential configurations. |
| 3, 7, 8, 14 | Output (OUT) | Four rail-to-rail outputs capable of sourcing/sinking ≥20 mA each into 600 Ω loads. |

| 11 | Positive Supply (V+) | Primary power input; supports 2.5–5.5 V with <1.3 mA total quiescent draw. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Output | Delivers full 0–5 V swing into 2 kΩ, enabling maximum ADC utilization without level-shifting circuitry. |
| Low Input Offset Drift | 1 µV/°C TCVOS - maintains <10 µV drift over 0–70°C ambient, critical for precision DC-coupled sensors. |
| Capacitive Load Drive | Stable with ≥100 pF loads - eliminates need for isolation resistors when driving ADC input capacitance or long traces. |
| Wide Supply Range | Operates from 2.5 V (single-cell LiFePO₄) to 5.5 V (USB-regulated) - simplifies power architecture across product variants. |
| High PSRR/CMRR | 85 dB PSRR and 90 dB CMRR - suppresses switching regulator noise and EMI in compact handheld PCBs. |

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 |
|---|---|---|---|
| LMV824IDR | TSSOP-14 package (5.0 × 4.4 mm); identical electrical specs and pinout to LMV824M/NOPB. | Better thermal performance (RθJA = 135.6°C/W vs. 109.7°C/W) but requires finer-pitch assembly. | Select for higher-density boards where SOIC footprint is prohibitive; verify reflow profile for TSSOP. |
| TLV2464CDR | Higher supply current (1.3 mA typ), wider GBW (6.4 MHz), lower VOS (2 mV max), but no AEC-Q100 qualification. | Preferred for higher-precision, higher-speed applications where automotive qualification is not required. | Choose when >5 MHz bandwidth or <2 mV offset is mandatory; avoid in automotive-grade designs. |
Compared with LMV824M/NOPB, LMV824IDR offers identical functionality in a smaller TSSOP package for space-constrained layouts, while TLV2464CDR trades higher power for improved speed and offset - making it suitable only where those gains outweigh cost and qualification requirements.

FAQ
What is the operating temperature range for LMV824M/NOPB?
The LMV824M/NOPB is rated for industrial operation from –40°C to +85°C. It is not the automotive-grade variant (LMV824-N-Q1), which extends to +125°C. All DC and AC specifications in the datasheet - including input offset voltage, gain-bandwidth, and slew rate - are guaranteed across this full industrial range, with test conditions explicitly defined for both 25°C and extreme temperatures.
Does LMV824M/NOPB support true rail-to-rail input?
No, LMV824M/NOPB 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 - meaning it accepts signals down to ground but cannot swing fully to V+. However, its rail-to-rail output capability (within 160 mV of rails into 600 Ω) remains fully functional and is a core design feature of the LMV824M/NOPB.
Can LMV824M/NOPB drive a 100 pF capacitive load stably?
Yes, LMV824M/NOPB is explicitly characterized for stable operation with capacitive loads up to 100 pF, as confirmed in Section 8.3 ("Do's and Don'ts") and Figure 22–25 of the SNOS032I datasheet. Its internal compensation ensures ≥61° phase margin even with 100 pF load and 10 kΩ series resistance - eliminating need for external isolation resistors in typical ADC driver or cable-drive applications.
What is the maximum output current per channel for LMV824M/NOPB?
LMV824M/NOPB delivers ≥20 mA sourcing and ≥20 mA sinking per amplifier at 5 V supply, as specified in Section 6.10 (DC Electrical Characteristics 5V). Under worst-case conditions (e.g., 600 Ω load, 25°C), it sustains 20 mA continuously; peak currents up to 45 mA are allowed briefly but may impact long-term reliability if sustained at elevated ambient temperatures.
Is LMV824M/NOPB pin-compatible with other quad op-amps in SOIC-14?
LMV824M/NOPB follows the industry-standard SOIC-14 pinout for quad op-amps (pin 1 = OUT A, pin 2 = –IN A, pin 3 = +IN A, pin 4 = V–, etc.), matching devices like LM324, TL084, and MCP6004. However, electrical behavior differs significantly - especially input stage (CMOS vs. bipolar), supply range (2.5–5.5 V vs. wider), and output drive - so functional replacement requires validation of biasing, gain, and stability in the target circuit.
