Product details
Overview
LM2902PT from STMicroelectronics is a low-power quad operational amplifier in TSSOP-14 package, designed for single-supply operation from 3 V to 30 V or dual supplies (±1.5 V to ±15 V). It delivers 1.3 MHz gain bandwidth, 100 dB large-signal voltage gain, and input common-mode range extending to the negative rail-enabling ground-sensing applications in automotive sensor signal conditioning and industrial analog front-ends.
For engineers reviewing the LM2902PT datasheet, LM2902PT pinout, LM2902PT application, or LM2902PT equivalent, key selection criteria include its rail-to-rail input capability, 375 µA per-amplifier supply current, 20 nA input bias current, and guaranteed operation from –40 °C to +125 °C across automotive-grade variants.
Technical Context
The LM2902PT integrates four independent internally compensated op amps using PNP input stage architecture, enabling input voltages down to the negative supply rail. Its differential input voltage rating of ±32 V and common-mode input range of (VCC+) – 1.5 V support robust interfacing with sensors and transducers in noisy industrial environments.
Each amplifier features unity-gain stable compensation, 0.4 V/µs slew rate, and output short-circuit protection up to 20 mA. The device maintains stable performance across wide supply ranges without requiring external compensation, making it suitable for cost-sensitive, space-constrained designs where power efficiency and input-level flexibility are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM324DT | Higher input offset voltage (3 mV typ.), wider temp range (–40 °C to +105 °C), no AEC-Q100 qualification | Lacks automotive qualification; not recommended for safety-critical vehicle subsystems | Select when cost sensitivity outweighs automotive compliance and offset performance requirements |
| TSV914IPT | Higher GBW (8 MHz), lower input bias current (1 pA), rail-to-rail output, but narrower supply range (2.7–5.5 V) | Not suitable for 12 V+ industrial or automotive single-supply use due to 5.5 V max VCC | Prefer for battery-powered portable instruments needing higher speed and ultra-low input current |
Compared with LM2902PT, LM324DT trades automotive reliability and tighter offset for broader legacy compatibility, while TSV914IPT offers superior AC performance at the expense of supply voltage flexibility-making LM2902PT the optimal balance for ruggedized 3–30 V analog signal chains.

FAQ
Is LM2902PT pin-compatible with LM2902D in SO-14 package?
Yes-LM2902PT (TSSOP-14) and LM2902D (SO-14) share identical pin numbering and electrical functionality per channel. Mechanical layout differs (6.4 mm vs. 8.75 mm width), requiring PCB footprint revision, but schematic design and signal routing remain unchanged.
Can LM2902PT drive a 10 kΩ load at 30 V supply?
Yes-LM2902PT delivers high-level output voltage of 26 V (min.) into 2 kΩ and 27 V (min.) into 10 kΩ at 30 V supply and 25 °C. Output swing remains within 3 V of rails across full temperature range, supporting robust interfacing with ADC references and comparators.
Does LM2902PT require external compensation capacitors?
No-LM2902PT uses internal frequency compensation and is unity-gain stable. No external capacitor is needed for standard configurations. Stability is maintained across all specified supply voltages and load capacitances ≤100 pF without added phase margin risk.
What is the maximum input voltage allowed when VCC+ = 5 V?
Per datasheet Table 2, the common-mode input voltage range is (VCC+) – 1.5 V, so maximum valid input is 3.5 V. Absolute maximum rating allows up to 32 V, but operation above (VCC+) – 1.5 V risks phase reversal or increased input bias current beyond specification.
