LT1673IS8#PBF

Gain of 5 Stable Low Supply Current: 2µA Max per Amplifier Rail-to-Rail Input and Output Low Offset Voltage: 375µV Max Over-The-Top Inputs Operate Above V+ Gain Bandwidth Product: 12kHz Wide Supply Range: 2.2V to 36V Single Supply Input Range: -0.3V to 36V Low Input Bias Current: 250pA Low Input Offset Current: 20pA High AVOL: 100V/mV Minimum Driving 100kΩ Load Output Sources and Sinks 500µA Load Current Reverse Battery Protected to 18V The LT1672/LT1673/LT1674 are ultralow power (IS ≤ 2µA) decompensated (AV ≥ 5) op amps with precision specifications. The extremely low supply current is combined with excellent amplifier specifications: input offset voltage is 375µV maximum with a typical drift of only 0.4µV/°C, input offset current is 100pA maximum. A minimum open-loop gain (AVOL) of 100V/mV ensures that gain errors are small. The devices’ characteristics change little over the supply range of 2.2V to ±15V. Supply rejection is 90dB and the common mode rejection ratio is 90dB. Operation is specified for 3V, 5V and ±15V supplies. Reverse battery protection (-18V min) and inputs that operate above the positive supply make the LT1672/LT1673/LT1674 easy to use in harsh environments.
