Dual CMOS op-amp, 100 kHz GBW, 8-DIP — what the ratings mean for the bench
The LMC6062IN/NOPB is a dual CMOS operational amplifier from the LMC® series, packaged in an 8-pin DIP (0.300" width) for through-hole mounting. It draws 40 µA per channel from a 4.5 V to 15.5 V supply span, making it a fit for battery-powered or low-thermal-budget analog front-ends where every microamp counts. The 100 kHz gain-bandwidth product paired with a 0.035 V/µs slew rate sets the signal bandwidth ceiling — expect clean gain up to roughly 10 kHz at a gain of 10 before the slew rate starts limiting the large-signal response. For slow sensor outputs (thermocouples, strain gauges, pH probes) this is ample; for audio or fast ADC drivers it will round the edges.
Input stage — where the picoamp bias matters
Input bias current is 0.01 pA typical, a figure that stays in the femtoamp range across the -40°C to +85°C industrial temperature range. This means the LMC6062IN/NOPB can interface directly with high-impedance sources like photodiode detectors or pH electrodes without the leakage errors that bipolar-input op-amps introduce. Input offset voltage is trimmed to 100 µV typical, so the DC error in a gain-of-100 stage is about 10 mV at the output — no external nulling pot needed for most applications. The push-pull rail-to-rail output stage swings within millivolts of either supply rail, preserving headroom in low-voltage single-supply designs (e.g., 5 V or 3.3 V rails). Output current capability is 35 mA per channel, enough to drive a 2 kΩ load to the rails or a moderate capacitive load without oscillation.
Package and rework — the DIP advantage
The 8-DIP (0.300" body, 7.62 mm row spacing) is about as rework-friendly as a package gets. No hot-air station needed — a standard soldering iron with a chisel tip lifts the part cleanly without lifting pads. The 2.54 mm pin pitch means hand-soldering a replacement is trivial, and the 100 mil pin spacing matches perfboard or prototype sockets. No moisture sensitivity level (MSL) concern; DIPs are not moisture-sensitive and need no bake before reflow. The tube packaging keeps the leads straight and protected during storage.
