Texas Instruments LM2902BIPWR

Overview

LM2902BIPWR from Texas Instruments is a quadruple operational amplifier optimized for single-supply industrial applications, featuring 3V to 36V supply range, ±3mV max input offset voltage (25°C), 240µA typical quiescent current per amplifier, and rail-to-rail output swing within 20mV of V– at –40°C to +125°C. It serves as a drop-in replacement for legacy LM2902 variants in power supply monitoring, motor control feedback, and sensor signal conditioning circuits.

For engineers reviewing the LM2902BIPWR datasheet, LM2902BIPWR pinout, LM2902BIPWR application, or LM2902BIPWR equivalent, key selection criteria include its extended temperature rating (–40°C to +125°C), integrated EMI/RF filtering, 2kV HBM ESD rating, and compatibility with legacy LM2902 footprints in SOIC-14 packages.

Technical Context

The LM2902BIPWR implements four independent high-voltage op amps in a single monolithic IC, each with unity-gain stability and common-mode input voltage range extending to V–. Its architecture supports single-supply operation without level-shifting circuitry, enabling direct interfacing with ground-referenced sensors and ADCs.

It features internal EMI/RF filtering and low input bias current (≤35nA max across –40°C to +125°C), making it suitable for noisy industrial environments where precision DC amplification and robustness against electromagnetic interference are required.

FAQ

What is the maximum operating temperature for LM2902BIPWR?

The LM2902BIPWR is rated for continuous operation from –40°C to +125°C ambient temperature. This specification is validated per JEDEC JESD22-A108 and applies across the full 3V to 36V supply range. The device maintains its ±3mV input offset voltage and 240µA quiescent current performance within this range, making LM2902BIPWR suitable for under-hood automotive modules and industrial motor drive control boards where thermal management is constrained.

Does LM2902BIPWR support true single-supply operation?

Yes, LM2902BIPWR supports true single-supply operation due to its common-mode input voltage range that includes V– (ground) and output swing within 20mV of V– at full temperature range. When VCC– is tied to ground and VCC+ is supplied with 5V–36V, the device accepts input signals down to ground and delivers output voltages down to 20mV above ground-enabling direct interface with ground-referenced sensors and 3.3V/5V ADCs without level-shifting circuitry. This behavior is confirmed in Section 6.3 and Figure 6-12 of the official LM2902B datasheet.

Is LM2902BIPWR pin-compatible with standard LM2902 SOIC-14 variants?

Yes, LM2902BIPWR uses the industry-standard 14-pin SOIC (D) package with identical pinout, pad layout, and mechanical dimensions (8.65mm × 6mm) as legacy LM2902, LM2902N, and LM2902DR devices. Pin functions-including 1IN–, 1IN+, 1OUT, VCC+, VCC–, and all remaining amplifier inputs/outputs-are electrically and physically identical. This allows LM2902BIPWR to serve as a drop-in replacement without PCB redesign, provided the application benefits from its improved offset voltage, extended temperature range, and integrated EMI filtering.

What is the ESD robustness of LM2902BIPWR?

LM2902BIPWR is rated for 2kV Human-Body Model (HBM) and 1.5kV Charged-Device Model (CDM) ESD protection per ANSI/ESDA/JEDEC JS-001 and JESD22-C101. These values exceed the 500V HBM rating of non-B LM2902 variants and reflect TI's enhanced process and layout hardening. The integrated EMI/RF filter further improves system-level immunity to fast transients. For handling, standard ESD precautions (wrist strap, grounded workstation) remain essential-but LM2902BIPWR tolerates higher static discharge events during board assembly and field service than predecessor parts.

Can LM2902BIPWR drive capacitive loads?

LM2902BIPWR is characterized to safely drive capacitive loads up to 100pF without oscillation or phase margin degradation, as specified in Section 6.6 of the datasheet. For loads exceeding 100pF (e.g., long traces or ADC input capacitance), TI recommends adding a small isolation resistor (10Ω–100Ω) in series with the output to maintain stability. This limitation arises from the device's 1.2MHz gain-bandwidth product and 56° phase margin; unlike rail-to-rail output op-amps with higher CLOAD ratings, LM2902BIPWR prioritizes precision and low IQ over high-capacitance drive strength.
