Analog Devices Inc. LTC2063 Zero-Drift Operational Amplifiers

Analog Devices LTC2063 Zero-Drift Operational Amplifiers are 20kHz zero-drift amplifiers designed to provide high-resolution measurements at extremely low-power levels. These micropower amplifiers typically consume only 1.3μA (2μA max) on a 1.8V supply. With its self-calibrating circuitry, the LTC2063 Amplifiers achieve a maximum 5μV at 25°C input offset voltage and 0.02μV/°C offset voltage drift from –40°C to 125°C. In addition, the op amps do not exceed a 100pA input bias current over the full specified temperature range. These high-precision input features enable the use of high-value power-saving resistors in the feedback network. This design maintains low-power consumption without compromising accuracy even when exposed to elevated temperatures. With its ultra-low quiescent current and outstanding precision, the LTC2063 can serve as a signal chain building block in energy harvesting, wireless sensor, and portable applications.

LTC2063's rail-to-rail inputs and outputs simplify single supply use and enhance the dynamic range. The integrated EMI filter offers 114dB electromagnetic interference rejection at 1.8GHz. Due to the low 1/f noise inherent to its zero-drift architecture, the LTC2063 is well-suited for amplifying and conditioning low-frequency sensor signals in high-temperature industrial and automotive systems.
