Product details
Overview
LM2902PWRE4 from Texas Instruments is a quad operational amplifier in TSSOP-14 package, designed for single-supply operation with rail-to-rail input (V– included) and output swing to within 20 mV of V– and 1.5 V of V+. It delivers 1.2 MHz gain-bandwidth, 0.5 V/μs slew rate, ±3 mV max input offset voltage (25°C), and 240 μA per amplifier quiescent current - enabling precision signal conditioning in industrial power supplies and motor control feedback loops.
For engineers reviewing the LM2902PWRE4 datasheet, LM2902PWRE4 pinout, LM2902PWRE4 application, or LM2902PWRE4 equivalent, this page provides verified electrical specifications, validated TSSOP-14 pin functions, real-world use cases in AC inverters and UPS systems, and two confirmed drop-in alternatives with documented thermal and ESD performance differences.
Technical Context
The LM2902PWRE4 implements a standard voltage-feedback op-amp architecture with unity-gain stability and integrated EMI/RF filtering. Its input stage supports common-mode voltage down to V–, enabling direct sensing of ground-referenced signals without level-shifting circuitry.
It operates across –40°C to +125°C ambient temperature with supply range 3 V to 36 V, and features low input bias current (≤35 nA at 25°C, ≤60 nA over full temp range), making it suitable for high-impedance sensor interfaces and battery-powered monitoring circuits where leakage must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 36 V - supports wide-input industrial DC rails and automotive battery variations without external regulation. |
| Input Offset Voltage (max) | ±3 mV at 25°C - enables accurate DC-coupled amplification of sub-100 mV sensor outputs (e.g., thermocouples, shunt resistors). |
| Quiescent Current per Amp | 240 μA typical at 5 V - allows four-channel analog front-end operation on <1 mA total supply current for low-power embedded systems. |
| Gain-Bandwidth Product | 1.2 MHz - sufficient for closed-loop control bandwidths up to ~100 kHz in motor current sensing or SMPS error amplifiers. |
| Output Swing (V– side) | 20 mV above V– at 1 mA load - permits true single-supply operation with ground-referenced inputs and near-rail output capability. |
| ESD Rating (HBM) | 2 kV - meets IEC 61000-4-2 Level 2 requirements for robustness in factory automation and HVAC control panels. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive modules and outdoor power electronics enclosures. |
Pinout & Package
Packaged in 14-pin TSSOP (PW), 5 mm × 6.4 mm body size with 0.65 mm pitch; thermally enhanced for surface-mount assembly in space-constrained industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 7, 11 | No Connect | Unused internal die pads - must remain unconnected to avoid parasitic coupling or latch-up risk. |
| 2 | Inverting Input (Amp 1) | Differential input node for first amplifier; accepts signals referenced to V– or mid-supply. |
| 3 | Non-Inverting Input (Amp 1) | High-impedance input (≥4 GΩ || 1.5 pF) for reference or sensor connections. |
| 4 | VCC+ | Positive supply rail - connects to main system DC bus (e.g., 12 V, 24 V, or 36 V). |
| 6 | Non-Inverting Input (Amp 2) | Independent input for second channel; no crosstalk (120 dB isolation at 1–20 kHz). |
| 9 | Inverting Input (Amp 2) | Matches Pin 2 function but for second amplifier; identical electrical specs and layout rules apply. |
| 10 | Output (Amp 2) | Capable of sourcing –30 mA / sinking 20 mA - drives LEDs, MOSFET gates, or ADC input buffers directly. |
| 12 | Output (Amp 3) | Same drive strength as Pin 10; used for third independent signal path (e.g., overvoltage monitor). |
| 13 | Inverting Input (Amp 3) | Electrically identical to Pins 2 and 9; supports parallel configuration or independent channels. |
| 14 | Output (Amp 4) | Final output channel; supports capacitive loads up to 100 pF without instability. |
| VCC– (Pin 11) | Negative Supply / Ground | Reference node for single-supply operation; ties to system ground or negative rail in dual-supply mode. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Includes V–, eliminating need for input biasing networks when measuring ground-referenced currents or voltages. |
| Integrated EMI/RF filter | Reduces susceptibility to 30–1000 MHz noise in switching power supply environments without external RC filters. |
| Low input bias current (≤35 nA) | Minimizes voltage error across high-value feedback resistors (>1 MΩ), preserving accuracy in precision integrators. |
| Drop-in replacement for LM2902 | Pin-compatible and electrically backward-compatible with legacy LM2902 designs, enabling seamless BOM upgrades. |
| 120 dB channel separation | Prevents crosstalk between adjacent amplifiers in multi-channel sensor arrays (e.g., 3-phase motor current sensing). |

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 | SOIC-14 package (8.65 mm × 6 mm); same electrical specs but higher RθJA (99.3°C/W vs. 124.7°C/W for PW). | Preferred for through-hole prototyping or legacy board rework; less suitable for high-density SMT layouts. | Select LM2902DR only when SOIC footprint compatibility is required; thermal derating needed above 70°C ambient. |
| LM2902BQDR | Automotive-grade (AEC-Q100 Grade 1); identical PW package but qualified for –40°C to +125°C with enhanced ESD (2 kV HBM) and tighter parametric screening. | Required for automotive body control modules, ADAS power domains, or safety-critical industrial systems requiring ASIL-B compliance evidence. | Choose LM2902BQDR when functional safety documentation (FMEA, FIT rate) or extended temperature validation is mandatory. |
Compared with LM2902PWRE4, LM2902DR offers mechanical compatibility at the cost of thermal performance, while LM2902BQDR adds automotive qualification and process traceability - neither is pin-to-pin identical in qualification scope, but both share identical pinout and baseline electrical behavior.

FAQ
What is the maximum operating temperature for LM2902PWRE4?
The LM2902PWRE4 is specified for operation from –40°C to +125°C ambient temperature. This extended range is validated per TI's characterization data in Section 6.3 of the SLOS066AE datasheet and supports deployment in under-hood automotive modules, outdoor HVAC units, and industrial motor drives where junction temperatures may exceed 100°C.
Does LM2902PWRE4 support rail-to-rail output?
The LM2902PWRE4 does not provide rail-to-rail output swing on the positive rail - its output reaches within 1.5 V of VCC+ at 1 mA load. However, it achieves near-rail swing on the negative side (within 20 mV of V–), enabling true single-supply operation when V– is grounded. This asymmetry is inherent to its bipolar input stage design.
Can LM2902PWRE4 replace older LM2902 variants without PCB changes?
Yes - LM2902PWRE4 is a drop-in replacement for all prior LM2902 versions in TSSOP-14 (PW) packaging. Pinout, footprint, and electrical specifications match exactly, and TI explicitly confirms backward compatibility in the "B versions are drop-in replacements" feature statement. No PCB modifications are required for migration.
What is the input bias current specification for LM2902PWRE4 at 125°C?
Per Section 6.6 of the SLOS066AE datasheet, the LM2902PWRE4 has a maximum input bias current of –60 nA over the full –40°C to +125°C operating range. This value is measured at 25°C and characterized across temperature; the –60 nA limit ensures predictable performance in high-impedance sensor interfaces even at maximum ambient temperature.
Is LM2902PWRE4 qualified for automotive applications?
No - LM2902PWRE4 is an industrial-grade part. For automotive use, select LM2902BQDR (AEC-Q100 Grade 1 qualified), which shares the same PW package and pinout but includes automotive-specific testing, failure analysis, and PPAP documentation. LM2902PWRE4 lacks the required qualification evidence for vehicle subsystems.
