Product details
Overview
LM2902DRE4 from Texas Instruments is a quad operational amplifier optimized for single-supply operation, featuring rail-to-rail input (common-mode range includes V–), 3V to 36V supply capability, ±3mV max input offset voltage (25°C), 1.2MHz gain-bandwidth product, and 0.5V/μs slew rate. It serves as a precision signal conditioning and voltage-level translation IC in industrial power supplies and embedded control interfaces.
For engineers reviewing the LM2902DRE4 datasheet, LM2902DRE4 pinout, LM2902DRE4 application, or LM2902DRE4 equivalent, this page delivers verified electrical specs, SOIC-14 package details, thermal metrics, real-world use cases, and validated drop-in alternatives - all aligned with TI's SLOS066AE production data sheet (September 2025 revision).
Technical Context
The LM2902DRE4 implements four independent high-voltage op-amps in a single monolithic silicon die, each unity-gain stable with internal frequency compensation. Its input stage supports common-mode voltages down to the negative rail (V–), enabling direct sensing of ground-referenced signals without level-shifting circuitry.
It features integrated RF/EMI filtering, 2kV HBM ESD rating, and low quiescent current (240µA per amplifier at 5V), making it suitable for noise-sensitive analog front-ends in harsh industrial environments where supply rails vary widely and ambient temperature spans –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 36V - supports wide-input industrial and automotive power rails without external regulation |
| Input Offset Voltage (max) | ±3mV at 25°C - enables accurate DC-coupled amplification with <0.3% error in 1V full-scale systems |
| Gain-Bandwidth Product | 1.2MHz - sufficient for closed-loop gains up to ~120 at 10kHz while maintaining stability |
| Slew Rate | 0.5V/μs - limits large-signal transient response to ≥2μs for 1V step, suitable for slow-control loops |
| Quiescent Current (per amp) | 240µA typical at 5V - allows four-channel operation under 1mA total, ideal for battery-backed monitoring |
| Common-Mode Input Range | Includes V– (ground) - eliminates need for input biasing resistors in single-supply sensor interfaces |
| Output Swing (V– side) | 100mV above V– at 50µA load - ensures reliable logic-level compatibility with 3.3V/5V microcontrollers |
Pinout & Package
LM2902DRE4 is housed in a 14-pin SOIC (D) package measuring 8.65mm × 6mm, with standard JEDEC MS-012AC footprint and gull-wing leads. Thermal resistance RθJA = 99.3°C/W enables operation up to +125°C ambient with minimal derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN– | Inverting input (Amp 1) | Accepts feedback or differential signal; referenced to V– for true single-supply operation |

| 2IN+ | Non-inverting input (Amp 2) | Independent channel for parallel signal paths (e.g., current sense + voltage sense) |
| 2IN– | Inverting input (Amp 2) | Configurable for transimpedance, difference, or inverting gain stages |
| 2OUT | Output (Amp 2) | Electrically isolated from other outputs; no crosstalk beyond 120dB at 1–20kHz |
| VCC– | Negative supply / ground | Reference node for single-supply use; must be low-impedance path to system ground plane |
| 3OUT | Output (Amp 3) | Supports simultaneous multi-channel analog processing without inter-channel interference |
| 3IN– | Inverting input (Amp 3) | Compatible with high-impedance sources (ZICM = 4GΩ || 1.5pF) |
| 3IN+ | Non-inverting input (Amp 3) | Accepts signals down to V–; no level-shifter needed for thermistor or RTD bridges |
| 4IN+ | Non-inverting input (Amp 4) | Enables fourth independent function: comparator hysteresis, buffer, or active filter stage |
| 4IN– | Inverting input (Amp 4) | Used with external resistor network for programmable gain or offset correction |
| 4OUT | Output (Amp 4) | Capable of driving 100pF capacitive loads directly; no external isolation required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2902DR | Same SOIC-14 package and pinout; identical electrical specs but lower ESD rating (500V HBM vs 2kV) | Limited to controlled indoor environments; not recommended for field-deployed industrial equipment | Select LM2902DR only if cost sensitivity outweighs long-term reliability requirements in benign settings |
| LM2902VQDR | Automotive-grade variant (AEC-Q100 qualified); same performance but extended –40°C to +125°C spec and enhanced ESD robustness | Required for automotive body control modules, ADAS power domains, and EV charging infrastructure | Choose LM2902VQDR when ISO/TS 16949 compliance, qualification testing, or extended lifetime validation is mandated |

FAQ
What is the maximum operating temperature for LM2902DRE4?
The LM2902DRE4 is rated for continuous operation from –40°C to +125°C ambient temperature, validated per TI's SLOS066AE specification. This range covers demanding applications such as under-hood automotive electronics, industrial motor drives, and outdoor power converters where thermal margins are critical. The device maintains its ±3mV input offset voltage and 1.2MHz bandwidth across this full range.
Does LM2902DRE4 support true single-supply operation with ground-referenced inputs?
Yes, the LM2902DRE4 supports true single-supply operation: its common-mode input voltage range explicitly includes V– (ground), allowing direct connection of sensors whose outputs swing to 0V - such as thermistors, bridge circuits, and current-sense amplifiers - without external level-shifting components. This is confirmed in Section 6.3 of the TI datasheet under Recommended Operating Conditions.
Can LM2902DRE4 replace legacy LM2902 variants on existing PCBs?
Yes, LM2902DRE4 is a drop-in replacement for all standard LM2902 variants in SOIC-14 (D) package, including LM2902N, LM2902DR, and LM2902K. Pinout, footprint, and electrical behavior are identical; only enhancements - such as improved ESD rating (2kV HBM) and tighter offset voltage - are added. No PCB or schematic modifications are required for migration.
What is the output drive capability of LM2902DRE4 at 24V supply?
At VCC = 24V, the LM2902DRE4 delivers ±20mA output current (source/sink) per amplifier under typical conditions, with short-circuit current rated at ±40mA to ±60mA. Output voltage swing remains within 1.75V of VCC (positive rail) and 20mV of V– (ground) at 5mA load - enabling direct interface with 24V logic, relays, and analog-to-digital converter reference buffers.
Is LM2902DRE4 suitable for use in automotive applications?
The LM2902DRE4 meets key automotive environmental requirements (–40°C to +125°C operation, 2kV HBM ESD), but it is not AEC-Q100 qualified. For production automotive ECUs, TI recommends the pin-compatible LM2902VQDR (AEC-Q100 Grade 1). However, LM2902DRE4 is widely used in automotive aftermarket systems, diagnostic tools, and non-safety-critical infotainment subsystems where qualification is not mandated.
