up, reducing total system power. n Rail-to-Rail Input and Output n 1.7V to 5.25V Operating Supply Range The LTC2066/LTC2067/LTC2068’s self-calibrating cir- n A cuitry results in very low input offset (5µV max) and offset VOL: 140dB Typical n Low-Charge Power-Up for Duty Cycled Applications drift (0.02µV/°C). The maximum input bias current is only n Specified Temperature Ranges: 35pA and does not exceed 150pA over the full specified n –40°C to 85°C temperature range. The extremely low input bias current n –40°C to 125°C of the LTC2066/LTC2067/LTC2068 allows the use of high n SC70, TSOT23, MS8, DFN10, TSSOP14 and value power-saving resistors in the feedback network. QFN16 Packages With its ultralow quiescent current and outstanding pre- cision, the LTC2066/LTC2067/LTC2068 can serve as a
