Product details
Overview
LTC2066HSC6#TRMPBF from Analog Devices is a single-channel, zero-drift operational amplifier in 6-lead SC70 package, designed for ultra-low-power precision signal conditioning. It delivers 10µA max supply current, 5µV max input offset voltage, 0.02µV/°C max offset drift, and rail-to-rail input/output operation across 1.7V to 5.25V supply - enabling high-resolution current sensing and sensor interfaces in energy-constrained systems.
For engineers reviewing the LTC2066HSC6#TRMPBF datasheet, LTC2066HSC6#TRMPBF pinout, LTC2066HSC6#TRMPBF application, or LTC2066HSC6#TRMPBF equivalent, key selection criteria include its –40°C to 125°C extended temperature rating, integrated EMI filter (90dB rejection at 1.8GHz), shutdown current ≤170nA, and guaranteed 35pA max input bias current over full temperature range.
Technical Context
The LTC2066HSC6#TRMPBF employs auto-zeroing and chopper-stabilized architecture with 25kHz internal chopping frequency to eliminate 1/f noise and minimize DC errors. Its self-calibrating circuitry achieves sub-microvolt offset stability without external trimming.
It features an integrated EMI filter optimized for RF immunity up to 2.4GHz and a dedicated SHDN pin referenced to V–, enabling low-charge power-up transients critical for duty-cycled sensor nodes. The amplifier maintains rail-to-rail operation and 140dB open-loop gain while operating down to 1.7V supply.

FAQ
What is the maximum operating temperature specification for the LTC2066HSC6#TRMPBF?
The LTC2066HSC6#TRMPBF is fully specified over the –40°C to +125°C junction temperature range, with guaranteed performance including 5µV max input offset voltage, 35pA max input bias current, and 170nA max shutdown current across this entire range. This H-grade rating distinguishes it from the I-grade (–40°C to +85°C) variants like LTC2066ISC6#TRMPBF.
Does the LTC2066HSC6#TRMPBF require external capacitors on its supply pins?
Yes, the LTC2066HSC6#TRMPBF requires a 100nF ceramic capacitor placed as close as possible between the V+ and V– pins and ground. This decoupling is essential to maintain stability, suppress supply noise, and ensure proper operation of the internal EMI filter and auto-zero circuitry. Omitting it may cause oscillation or degraded PSRR.
How does the SHDN pin function on the LTC2066HSC6#TRMPBF?
The SHDN pin on the LTC2066HSC6#TRMPBF is referenced to V–. Driving it to V– places the device in shutdown mode, drawing ≤170nA per amplifier. Driving it to ≥1.8V (relative to V–) enables normal operation. The pin must not be left floating, and its threshold is guaranteed at 0.8V (low) and 1.8V (high) over temperature.
Can the LTC2066HSC6#TRMPBF drive a 10kΩ load while maintaining rail-to-rail output swing?
Yes, the LTC2066HSC6#TRMPBF delivers rail-to-rail output swing into a 10kΩ load: VOH is within 20mV of V+, and VOL is within 20mV of V–, at room temperature and full supply range. Performance degrades slightly at extremes of temperature and supply voltage but remains within 50mV of rails across –40°C to 125°C.
Is the LTC2066HSC6#TRMPBF susceptible to clock feedthrough artifacts?
Like all zero-drift amplifiers, the LTC2066HSC6#TRMPBF exhibits clock feedthrough due to its 25kHz chopping frequency. However, its input switching currents are minimized, and the effect is attenuated by closed-loop bandwidth limiting. For critical applications, adding a small capacitor (e.g., 10–100pF) across the feedback resistor effectively filters residual feedthrough without compromising DC accuracy.
