Active production, low-offset signal chain
The MAX4238ATT+T: With a 0.1 µV typical input offset voltage and 1 pA input bias current, this op amp resolves microvolt-level signals from high-impedance sources like photodiodes or thermocouples without the drift a bipolar input stage would introduce.
1 MHz GBW, 0.35 V/µs slew rate
The 1 MHz gain-bandwidth product and 0.35 V/µs slew rate suit it for low-frequency sensor amplification, active filtering below 100 kHz, and control-loop compensation where phase margin matters more than raw speed.
ROHS3 compliant per, with no exemptions beyond the standard lead-free reflow profile.
