The STMicroelectronics LM2902HD is a quad general-purpose operational amplifier in a surface-mount package.
Input bias current is 20 nA typical, and input offset voltage is 2 mV, both adequate for non-precision signal chains where the 150°C rating is the overriding selection criterion.
A pin-compatible alternative in the same 14-SOIC footprint with a 150°C temperature rating would need to be qualified against the original design's supply voltage range (3 V to 30 V), gain-bandwidth (1.3 MHz), and slew rate (0.4 V/µs). Cross-reference searches against other quad general-purpose op-amps with extended temperature range are recommended.
The electrical specifications — gain-bandwidth, slew rate, input bias, and offset — are otherwise the same. The HD variant was specified for applications requiring higher junction temperature margin.
