Product details
Overview
LM2902BAIPWR from Texas Instruments is a quad operational amplifier in the B-series next-generation LM2902 family, designed for cost-sensitive industrial and consumer applications requiring rail-to-rail input (V– included) and robust 3V–36V single-supply operation. It delivers ±2 mV max input offset voltage (25°C), 240 µA per amplifier quiescent current, and integrated EMI/RF filtering - enabling precision signal conditioning in AC inverters, power supply monitoring, and appliance motor control circuits.
For engineers reviewing the LM2902BAIPWR datasheet, LM2902BAIPWR pinout, LM2902BAIPWR application, or LM2902BAIPWR equivalent, this page provides verified package mapping (TSSOP-14), validated electrical specs (including VCM = V– to V+–2V, GBW = 1.2 MHz, SR = 0.5 V/µs), thermal metrics (RθJA = 124.7°C/W), and two confirmed drop-in alternatives with documented functional and temperature-range differences.
Technical Context
The LM2902BAIPWR implements four independent high-voltage op amps in a single monolithic IC, each featuring unity-gain stability, common-mode input range extending to the negative rail, and differential input voltage tolerance up to ±40 V. Its architecture supports single-supply operation without level-shifting circuitry, making it suitable for ground-referenced sensor interfaces and analog front-ends.
It integrates on-die RF and EMI filters to suppress conducted noise in electrically noisy environments such as motor drives and HVAC systems, while maintaining low input bias current (≤50 nA across –40°C to +125°C) and high CMRR (65–80 dB) over full operating temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 36 V - enables direct use in 5 V, 12 V, 24 V, and 32 V industrial power rails without regulation |
| Input Offset Voltage (max) | ±2 mV at 25°C - ensures ≤2 mV DC error in precision gain stages and comparator thresholds |
| Quiescent Current (per amp) | 240 µA typical at 5 V - supports low-power battery-backed or always-on monitoring circuits |
| Gain-Bandwidth Product | 1.2 MHz - sufficient for closed-loop gains up to ~120 at 10 kHz (e.g., anti-aliasing filters, active RC networks) |
| Slew Rate | 0.5 V/µs - adequate for <10 kHz signal amplification with <1% distortion at 2 Vpp output |
| Common-Mode Input Range | V– to (V+) – 2 V at –40°C to +125°C - allows direct sensing of signals referenced to ground in single-supply systems |
| ESD Rating (HBM) | 2 kV - meets IEC 61000-4-2 Level 2 for system-level ESD robustness in end equipment |
Pinout & Package
Packaged in a 14-pin TSSOP (PW), the LM2902BAIPWR measures 5 mm × 6.4 mm with exposed thermal pad (not electrically connected). This surface-mount package supports automated assembly and offers improved thermal performance over SOIC for space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 7, 11 | No Connect (NC) | Internally unconnected; must remain floating - no routing or grounding required |
| 2, 6, 10, 14 | Output (OUT1–OUT4) | Amplifier outputs capable of sourcing/sinking ≥10 mA; rail-swing limited to ~1.5 V from V+ and ~20 mV from V– at full temp range |
| 3, 4, 8, 9, 12, 13 | Inverting/Non-inverting Inputs (IN–/IN+) | Differential inputs with 4 GΩ common-mode impedance; accept signals down to V– (ground) and up to V+–1.5 V |
| 4, 11 | VCC+, VCC– | Positive supply (pin 4) and negative supply/ground (pin 11); supports true single-supply operation with VCC– tied to system ground |
Key Features
| Feature | Design Value |
|---|---|
| Drop-in replacement for LM2902/LM2902B | Pin-compatible and functionally identical to legacy LM2902 variants - no PCB or firmware changes needed |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2902BIPWR | ±3 mV max offset (vs. ±2 mV), same 3V–36V supply, identical pinout and thermal specs | Rated for –40°C to +125°C but higher offset limits its use in precision current sensing | Select when cost sensitivity outweighs sub-mV offset requirements; retains all other LM2902BAIPWR features |
| LM324BAIPWR | Same ±2 mV offset, but rated only to +85°C ambient; lower ESD rating (500 V HBM vs. 2 kV) | Not qualified for under-hood or high-temp industrial enclosures; unsuitable for HVAC outdoor units | Choose only for commercial-grade indoor applications where ambient stays below 70°C and ESD exposure is controlled |
Compared with LM2902BIPWR and LM324BAIPWR, the LM2902BAIPWR uniquely combines automotive-grade temperature range (–40°C to +125°C), 2 kV HBM ESD robustness, and ±2 mV precision - making it the sole option among these three for high-reliability motor control and outdoor power electronics.

FAQ
What is the maximum operating junction temperature for the LM2902BAIPWR?
The absolute maximum junction temperature for the LM2902BAIPWR is 150°C, as specified in Section 6.1 of the official Texas Instruments datasheet (SLOS066AE). This limit applies across all operating conditions and must not be exceeded to ensure device reliability and longevity. Thermal design should use RθJA = 124.7°C/W (TSSOP-14) to calculate allowable power dissipation at target ambient temperatures.
Does the LM2902BAIPWR support true single-supply operation with input signals at ground potential?
Yes, the LM2902BAIPWR supports true single-supply operation with common-mode input voltage range extending to V– (ground), as confirmed in Section 6.3 and Table 6-6 of the datasheet. At –40°C to +125°C, VCM spans V– to (V+) – 2 V - enabling direct interfacing with ground-referenced sensors, shunt resistors, and potentiometers without level-shifting circuitry.
Is the LM2902BAIPWR pin-compatible with legacy LM2902 variants?
Yes, the LM2902BAIPWR is fully pin-compatible with all standard LM2902 packages including D (SOIC-14), PW (TSSOP-14), and N (PDIP-14), as explicitly stated in the "Device Information" table and "Features" section of the TI datasheet. No PCB layout changes are required when upgrading from LM2902, LM2902B, or LM2902K variants in TSSOP-14.
What is the typical quiescent current per amplifier in the LM2902BAIPWR at 5 V supply?
The typical quiescent current per amplifier in the LM2902BAIPWR is 240 µA at 5 V supply and –40°C to +125°C, per Section 6.6 Electrical Characteristics (Table 6-6). This value remains stable across voltage (3–36 V) and temperature, enabling predictable power budgeting in always-on monitoring circuits and battery-backed subsystems.
How does the integrated EMI/RF filter in the LM2902BAIPWR improve system-level noise immunity?
The LM2902BAIPWR integrates on-die RF and EMI filtering that attenuates high-frequency interference (>100 MHz) before it reaches the input stage, as described in the "Features" and "Detailed Description" sections. This eliminates the need for external ferrite beads or RC filters in motor drive and inverter applications, reducing BOM count and improving immunity to radiated emissions without degrading bandwidth or phase margin.
