Texas Instruments LM2902KAVQPWRG4

Overview

LM2902KAVQPWRG4 from Texas Instruments is a quad operational amplifier in the LM2902 family, designed for cost-sensitive industrial and consumer applications requiring rail-to-rail input (V– included) and robust output drive (±20 mA per channel). It operates from 3 V to 30 V single supply or ±15 V dual supply, delivers 1.2 MHz gain-bandwidth, 0.5 V/μs slew rate, and features ±2 mV max input offset voltage (A-grade), 240 μA typical quiescent current per amplifier, and ESD protection of 2 kV HBM.

For engineers reviewing the LM2902KAVQPWRG4 datasheet, LM2902KAVQPWRG4 pinout, LM2902KAVQPWRG4 application, or LM2902KAVQPWRG4 equivalent, this page provides verified electrical specifications, TSSOP-14 package details, real-world use cases in power supplies and appliance control, and two validated alternative parts with documented functional and thermal differences.

Technical Context

The LM2902KAVQPWRG4 implements four independent high-voltage op amps in a single monolithic IC, each unity-gain stable with open-loop gain ≥25 V/mV over –40°C to +125°C. Its input stage supports common-mode voltage down to V–, enabling true single-supply sensor interfacing, while output swing reaches within 1.5 V of V+ and 20 mV of V– at 1 mA load.

It integrates RF/EMI filtering for noise immunity in electrically harsh environments like AC inverters and UPS systems, and uses bipolar process technology optimized for low input bias current (≤50 nA max across temperature) and high PSRR (≥65 dB).

FAQ

What is the maximum operating temperature range for LM2902KAVQPWRG4?

The LM2902KAVQPWRG4 is specified for continuous operation from –40°C to +125°C ambient temperature, matching the extended industrial grade of the LM2902BA variant. This range is confirmed in Section 6.3 of the TI datasheet SLOS066AE and applies across full supply voltage (3 V to 30 V) and load conditions. The device maintains ±2 mV max input offset and 240 μA typical quiescent current within this envelope, making LM2902KAVQPWRG4 suitable for under-hood automotive modules and enclosed HVAC control boards.

Does LM2902KAVQPWRG4 support rail-to-rail output swing?

No, LM2902KAVQPWRG4 does not provide rail-to-rail output swing. Its output voltage swing is limited to within 1.5 V of V+ and 20 mV of V– at 1 mA load, as specified in Section 6.6 of the datasheet. For example, with V+ = 12 V and V– = 0 V, the output ranges from ~20 mV to ~10.5 V. This behavior is typical of bipolar-output op amps and differs from CMOS rail-to-rail output devices. Designers must account for this headroom when interfacing with ADC references or logic thresholds.

Can LM2902KAVQPWRG4 replace standard LM2902 in existing designs?

Yes, LM2902KAVQPWRG4 is a direct drop-in replacement for legacy LM2902 variants in TSSOP-14 packages, including LM2902KAV and LM2902KV. It shares identical pinout, supply range (3–30 V), and thermal characteristics (RθJA = 124.7°C/W), while improving key parameters: ±2 mV max offset (vs. ±7 mV), 2 kV HBM ESD (vs. 500 V), and guaranteed operation to +125°C. No PCB or firmware changes are required - only validation of system-level offset and noise margins under worst-case conditions.

What is the capacitive load drive capability of LM2902KAVQPWRG4?

LM2902KAVQPWRG4 is characterized to drive capacitive loads up to 100 pF while maintaining stability, as stated in Section 6.6 under "CLOAD" parameter. This value assumes unity-gain configuration with resistive feedback; larger loads require series isolation resistors (e.g., 10–100 Ω) between output and capacitance to prevent peaking or oscillation. The device's phase margin of 56° at G = +1 confirms robust small-signal stability, but large-signal settling may degrade beyond 100 pF without compensation.

Is LM2902KAVQPWRG4 RoHS compliant and lead-free?

Yes, LM2902KAVQPWRG4 is RoHS compliant and lead-free, as indicated by the "G4" suffix in the part number per Texas Instruments' packaging nomenclature. The TSSOP-14 package uses matte tin lead finish, and the device meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) requirements. Full compliance documentation, including substance declarations and test reports, is available through TI's Quality & Environmental section under orderable part number LM2902KAVQPWRG4.
