The NEC UPC4061C-A is a single JFET-input operational amplifier in an 8-DIP through-hole package. The 1 MHz gain-bandwidth product and 3 V/µs slew rate cover audio-frequency loops and slow filter poles, though they won't support video or fast-switching regulator compensation.
Supply range and temperature — the design boundaries
The UPC4061C-A operates from a 4 V to 32 V supply span, so it runs on a single 5 V, 12 V, or 24 V industrial rail without a secondary regulator, or on split supplies up to ±16 V. The -20°C to 80°C ambient temperature range limits it to benchtop instruments, indoor control panels, and commercial equipment — not automotive or outdoor telecom cabinets without active cooling.
Output drive and input offset — practical margins
Each channel can source or sink 5 mA. That's enough to drive a following ADC input or a 2 kΩ load to near the rails, but not a relay coil or a 50 Ω transmission line. The 2 mV input offset voltage is typical for a general-purpose JFET op-amp; if your application needs sub-millivolt precision, plan for an offset-null trim or select a lower-Vos grade.
Package and supply current — board-level notes
The 8-DIP package (0.300" row spacing) fits standard breadboards and 0.1" pitch prototyping grids. Quiescent supply current is 220 µA per amplifier, so the part is frugal enough for battery-powered portable instruments that don't need the full industrial temperature range.
