Product details

Quad op-amp in a 14-TSSOP — automotive-rated and production-ready

Each of the four amplifiers delivers a gain-bandwidth product of 1.2 MHz and a slew rate of 0.5 V/µs, with a supply range from 3 V to 32 V. The quiescent current per amplifier is 1.4 mA, and each output can source or sink up to 60 mA. The 14-TSSOP footprint is a common surface-mount package for space-constrained PCBs.

The 1.2 MHz gain-bandwidth product sets the usable small-signal bandwidth for feedback loops — adequate for sensor conditioning, actuator drive, and general signal buffering in automotive ECUs. Input offset voltage is rated at 3 mV, and input bias current at 20 nA — typical for a general-purpose bipolar op-amp. These values are fine for non-critical DC accuracy; for precision sensing below 1 mV, consider a zero-drift or chopper-stabilized alternative. The 3 V to 32 V supply span covers both 5 V and 12 V automotive rails, and the 60 mA per-channel output current can directly drive small relays, LEDs, or MOSFET gates with appropriate base/gate resistors.

Package and mounting — shop-floor considerations

It is surface-mount only, so plan for a reflow profile compatible with lead-free solder. The part is ROHS3 compliant, so no special handling for restricted substances. No exposed thermal pad on this package — thermal dissipation relies on the leads and PCB copper. For continuous operation near the 125°C limit or with high output current, ensure adequate board-level heat sinking through wide traces and vias to internal planes.

Frequently asked questions

What is the slew rate of LM2902KAVQPWRQ1?

The slew rate is 0.5 V/µs, which limits large-signal bandwidth to roughly 40 kHz at 10 V output swing.

Can LM2902KAVQPWRQ1 replace LM324?

The LM2902KAVQPWRQ1 is pin-compatible with the industry-standard LM324 quad op-amp and shares a similar general-purpose architecture. However, it is specified for the -40°C to 125°C automotive temperature range and is AEC-Q100 qualified, whereas the LM324 is typically rated for 0°C to 70°C. For a direct drop-in in an automotive environment, this part is a suitable upgrade.

What is the difference between LM2902KAVQPWRQ1 and LM2902K?

The LM2902KAVQPWRQ1 is the automotive-grade variant in a 14-TSSOP package, qualified to AEC-Q100 and rated for -40°C to 125°C. The base LM2902K is typically offered in PDIP or SOIC packages and may not carry the same automotive qualification. The electrical specifications (1.2 MHz GBW, 0.5 V/µs slew rate, 3 V to 32 V supply) are essentially the same.
