Internal n Output Currents up to 1mA circuitry converts input voltage to output current, allowing n Operating Temperature Range: –40°C to 125°C a small sense signal on a large common mode voltage to n Disable Mode (LTC6102-1 Only): 1µA Maximum be translated to a ground-referred signal. Low DC offset n Available in 8-Lead MSOP and 3mm × 3mm allows the use of very low shunt resistor values and large DFN Packages gain-setting resistors. As a result, power loss in the shunt is reduced.
