Zero-drift precision in a tiny SC-70-6 package
The LTC2066HSC6#TRMPBF is a single-channel zero-drift operational amplifier from Analog Devices. Its 1 µV typical input offset voltage and 5 pA input bias current make it a natural fit for precision DC measurement, current sensing, and thermocouple amplification where drift over temperature would otherwise swamp the signal.
7.5 µA supply current — the trade-off you need to know
The 100 kHz gain-bandwidth product and 0.0175 V/µs slew rate tell you this is an ultralow-power part, not a high-speed amplifier. At 7.5 µA supply current, it's designed for battery-powered instrumentation and sensor interfaces that run continuously — think portable gas detectors, wearable medical patches, or remote IoT nodes that sleep most of the time but need accurate readings when awake. If your application needs to track kilohertz signals, this isn't the part; the bandwidth simply isn't there.
Temperature range and what it buys you
That's the full industrial temperature range plus a bit of headroom for self-heating.
Footprint reality — SC-70-6
The package is a 6-lead SC-70 (also known as SOT-363 or 6-TSSOP). That's a tiny footprint — roughly 2.0 mm × 2.1 mm — so layout needs care. The exposed pad is absent on this package; all dissipation goes through the leads. For a 7.5 µA part that's not an issue, but if you're running near the supply maximum, keep the copper pour under the device solid and use short traces to the bypass cap.
