Product details
Overview
LM2902WYPT from STMicroelectronics is a low-power quad operational amplifier in TSSOP-14 package, designed for single-supply (3–30 V) or dual-supply (±1.5–±15 V) operation with rail-to-rail input common-mode range down to the negative rail. It delivers 1.3 MHz gain bandwidth, 100 dB large-signal voltage gain, and 375 µA per amplifier supply current, enabling precision signal conditioning in automotive sensor interfaces and industrial control loops.
For engineers reviewing the LM2902WYPT datasheet, LM2902WYPT pinout, LM2902WYPT application, or LM2902WYPT equivalent, key selection criteria include its guaranteed -40°C to +125°C operating range, 2 nA input offset current, 800 V HBM ESD rating, and compatibility with high-impedance transducer front-ends requiring stable DC accuracy and low quiescent power.
Technical Context
The LM2902WYPT integrates four independent internally compensated op-amps optimized for wide-voltage single-supply operation. Its PNP-input stage enables input common-mode voltage down to VCC−, supporting ground-referenced sensing without level-shifting. The device maintains stable unity-gain performance up to 1.3 MHz while delivering 0.24–0.4 V/µs slew rate across temperature.
It features robust electrostatic protection (800 V HBM), thermal resistance of 100 °C/W (junction-to-ambient, TSSOP-14), and output short-circuit current limited to 20–70 mA. Input bias current remains constant at 20 nA (typ) over temperature, and large-signal voltage gain stays ≥25 V/mV across full operating range (-40°C to +125°C).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2902DT | SO-14 package, same electrical specs, non-automotive grade (industrial temp only: -40°C to +105°C) | Lacks AEC-Q100 qualification; unsuitable for automotive under-hood use | Select when cost-sensitive industrial designs require SO-14 footprint and do not need automotive qualification |
| LM2902AWYPT | Enhanced version with lower input offset voltage (2 mV max vs. 7 mV max) and tighter drift spec (7 µV/°C typ) | Better DC accuracy for 14+ bit data acquisition; same pinout and thermal specs | Choose for high-precision sensor front-ends where sub-5 mV offset is mandatory |
Compared with LM2902DT, LM2902WYPT adds automotive qualification and extended temperature margin; compared with LM2902AWYPT, it trades 5 mV higher Vos for lower unit cost while retaining identical packaging, ESD rating, and dynamic performance.

FAQ
What is the maximum capacitive load the LM2902WYPT can drive stably?
The LM2902WYPT maintains phase margin ≥25° with up to 100 pF capacitive load when driving a 2 kΩ load, as verified in Figure 22 of the DS3575 datasheet. For loads exceeding 100 pF, external series resistance (≥100 Ω) is recommended at the output to ensure stability in unity-gain configurations.
Does the LM2902WYPT support true rail-to-rail output swing?
No - the LM2902WYPT features rail-to-rail *input* common-mode range (down to VCC−), but its output swing is limited to within ~1.5 V of each rail under 2 kΩ load. At VCC+ = 30 V, VOH min is 26 V; at VCC+ = 5 V, VOL max is 35 mV. Output headroom is load- and temperature-dependent per Table 3.
Can the LM2902WYPT operate from a 3.3 V single supply?
Yes - the device is fully specified for 3 V to 30 V single-supply operation. At 3.3 V, it delivers 375 µA per amplifier supply current, 1.3 MHz GBP, and maintains input common-mode range from 0 V to 1.8 V. Output swing is ~0.1 V to ~3.2 V with light loads, making it suitable for interfacing with 3.3 V ADCs and microcontrollers.
How does the LM2902WYPT differ from the legacy LM2902N (DIP-14)?
The LM2902WYPT replaces the through-hole LM2902N with a surface-mount TSSOP-14 package, reduced thermal resistance (100 °C/W vs. ~150 °C/W), AEC-Q100 qualification, and tighter production screening. Electrical parameters are identical; only packaging, reliability testing, and thermal performance differ - no circuit redesign is needed for drop-in replacement in new layouts.
