J-FET input stage — low bias, moderate speed
The TL062CD is a dual J-FET input op-amp from STMicroelectronics, in an 8-SOIC package. Its J-FET input stage gives a 30 pA input bias current, which is useful when the source impedance is high and you cannot afford the offset from a bipolar input. The 1 MHz gain-bandwidth product and 3.5 V/µs slew rate put it in the audio and slow-control-loop class — not for high-speed ADC drivers or video buffers, but adequate for signal conditioning, active filters, and transducer amplification where the signal bandwidth stays below 100 kHz.
Supply range and current draw
Runs from a 6 V to 36 V total supply span, so it works on single 5 V rails (though with limited headroom) up to ±18 V dual supplies. Each channel draws 200 µA typical, making the pair 400 µA quiescent — low enough for battery-operated equipment that spends most of its time in a low-bandwidth sense mode.
Temperature grade — commercial only
No good for a motor drive cabinet or an outdoor telecom enclosure where the ambient can hit 85°C. If the board sits in a conditioned lab, office equipment, or an appliance that never freezes, the grade is fine. For industrial or automotive temperatures, you would step to the TL062ID or the TL062AI variants.
