LTC2063/LTC2064/LTC2065 2A Supply Current, Low I , Zero-Drift Operational Amplifiers B FEATURES DESCRIPTION n Low Supply Current: 2A Maximum (per Amplifier) The LTC 2063/LTC2064/LTC2065 are single, dual, n Offset Voltage: 5V Maximum and quad low power, zero-drift, 20kHz amplifiers. The n Offset Voltage Drift: 0.02V/C Maximum LTC2063/LTC2064/LTC2065 enable high resolution mea- n Input Bias Current: surement at extremely low power levels. n 3pA Typical Typical supply current is 1.4A per amplifier with a max- n 30pA Maximum, 40C to 85C imum of 2A. The available shutdown mode has been n 100pA Maximum, 40C to 125C optimized to minimize power consumption in duty-cycled n Integrated EMI Filter (114dB Rejection at 1.8GHz) applications and features low charge loss during pow- n Shutdown Current: 170nA Maximum (per Amplifier) er-up, reducing total system power. n Rail-to-Rail Input and Output n The LTC2063/LTC2064/LTC2065s self-calibrating cir- 1.7V to 5.25V Operating Supply Range n cuitry results in very low input offset (5V max) and offset A : 140dB Typical VOL n drift (0.02V/C). The maximum input bias current is only Low-Charge Power-Up for Duty Cycled Applications n 20pA and does not exceed 100pA over the full specified Specified Temperature Ranges: n temperature range. The extremely low input bias current 40C to 85C n of the LTC2063/LTC2064/LTC2065 allows the use of high 40C to 125C n value power-saving resistors in the feedback network.
