Product details
Overview
LM2902NS-MAND from Texas Instruments is a quad general-purpose operational amplifier optimized for single-supply operation across –40°C to 125°C. It delivers 0.8 mA typical supply current per device, 3 mV typical input offset voltage at 25°C, and rail-to-rail common-mode input range including ground-enabling direct low-side current sensing in automotive body control modules.
For engineers reviewing the LM2902NS-MAND datasheet, LM2902NS-MAND pinout, LM2902NS-MAND application, or LM2902NS-MAND equivalent, this page provides verified electrical parameters, thermal performance data, package-specific layout guidance, and validated drop-in alternatives for industrial sensor interfaces and automotive powertrain signal conditioning.
Technical Context
The LM2902NS-MAND integrates four independent, internally frequency-compensated op-amps with high open-loop gain (100 V/mV typ) and differential input voltage range up to ±26 V. Its input stage supports common-mode voltages down to ground, eliminating level-shifting circuitry in single-supply transducer amplifiers.
Designed for robustness in harsh environments, it features 7 mV maximum input offset voltage over full temperature range (–40°C to 125°C), 80 dB typical CMRR, and 100 dB typical supply-voltage rejection ratio-critical for precision DC amplification in noisy 12 V automotive systems.

| Input Bias Current | –20 nA typical; minimizes voltage error across high-impedance bridge sensor networks |
| Common-Mode Input Range | 0 V to VCC–1.5 V; allows direct connection of grounded thermistors or shunt resistors without biasing |
| Output Drive Capability | ±20 mA short-circuit current; supports direct driving of LED indicators or small relays |
| Temperature Range | –40°C to 125°C; qualified for under-hood engine control unit (ECU) and transmission control module (TCM) applications |
| Gain-Bandwidth Product | 0.4 MHz typical; sufficient for DC–10 kHz signal conditioning in battery management and HVAC feedback loops |
Pinout & Package
LM2902NS-MAND is supplied in the 14-pin SOIC (NS) package with standard industry pinout and 1.27 mm pitch. The package meets JEDEC MS-012 specifications and supports automated optical inspection (AOI) and reflow soldering per IPC-J-STD-020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM324DR | 0°C to 70°C temp range; 7 mV max VIO at 25°C vs. LM2902NS-MAND's 7 mV max over –40°C to 125°C | Not qualified for under-hood automotive use; suitable only for commercial-grade consumer electronics | Select LM324DR only for cost-sensitive non-automotive designs where extended temperature operation is unnecessary |
| LM2902PWR | Same –40°C to 125°C rating and 7 mV max VIO, but in TSSOP-14 (PW) package with 0.65 mm pitch | Requires finer-pitch PCB layout and reflow profile; not pin-compatible due to different pad geometry | Choose LM2902PWR when board space is constrained and assembly process supports TSSOP handling |
Compared with LM324DR and LM2902PWR, the LM2902NS-MAND uniquely combines automotive-grade temperature qualification, SOIC-14 manufacturability, and guaranteed ground-sensing capability-making it the optimal choice for production automotive ECUs requiring AEC-Q100 alignment and legacy PCB compatibility.

FAQ
What is the maximum supply voltage for LM2902NS-MAND?
The LM2902NS-MAND supports a maximum single-supply voltage of 26 V, as specified in its absolute maximum ratings. This limit applies across its full operating temperature range (–40°C to 125°C) and is lower than the 32 V rating of the LM324 family due to automotive qualification constraints. Exceeding 26 V risks permanent damage, even momentarily.
Does LM2902NS-MAND support rail-to-rail output swing?
No, the LM2902NS-MAND does not provide rail-to-rail output. Its high-level output voltage is typically VCC–1.5 V at 25°C with a 2 kΩ load, and low-level output is typically 5 mV above ground. This limited output swing is inherent to its bipolar input stage and must be accounted for in gain-setting calculations.
Can LM2902NS-MAND replace LM324N on an existing PCB?
Yes, LM2902NS-MAND is pin-compatible with LM324N in SOIC-14 (NS) and PDIP-14 (N) packages, sharing identical pinout and footprint. However, design validation is required for temperature range extension (–40°C to 125°C vs. 0°C to 70°C) and revised supply limits (26 V max vs. 32 V max).
What is the input offset voltage drift specification for LM2902NS-MAND?
The LM2902NS-MAND datasheet does not specify input offset voltage drift (µV/°C) as a guaranteed parameter. Typical drift is inferred from full-range VIO of 10 mV max (–40°C to 125°C) and 3 mV typ at 25°C, implying ≈0.06 µV/°C average drift-but this is not characterized or tested per production lot.
Is LM2902NS-MAND qualified to AEC-Q100 standards?
LM2902NS-MAND is not individually AEC-Q100 certified, but it is derived from the LM2902Q automotive-qualified family and shares identical die, process, and test flow. TI documents LM2902 variants as "designed to meet automotive requirements," with full temperature range (–40°C to 125°C) and enhanced ESD robustness (2 kV HBM) supporting automotive deployment.
