LTC6102 LTC6102-1/LTC6102HV Precision Zero Drift Current Sense Amplifier Fea T Descrip T n Supply Range: The LTC 6102/LTC6102HV are versatile, high voltage, high- 4V to 60V, 70V Maximum (LTC6102) side current sense amplifiers. Their high supply voltage 5V to 100V, 105V Maximum (LTC6102HV) rating allows their use in many high side applications, n 10V Input Offset Maximum while the low drift and offset ensure accuracy across a n 50nV/C Input Offset Drift Maximum wide range of operating conditions. The LTC6102-1 is a n Fast Response: 1s Step Response version of the LTC6102 that includes a low power disable n Gain Configurable with Two Resistors mode to conserve system standby power. n Low Input Bias Current: 3nA Maximum The LTC6102/LTC6102HV monitor current via the voltage n PSRR 130dB Minimum across an external sense resistor (shunt resistor). Internal n Output Currents up to 1mA circuitry converts input voltage to output current, allowing n Operating Temperature Range: 40C to 125C a small sense signal on a large common mode voltage to n Disable Mode (LTC6102-1 Only): 1A 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. a T The wide operating supply and high accuracy make the n LTC6102 ideal for a large array of applications, from auto- Current Shunt Measurement n motive, to industrial and power management. A maximum Battery Monitoring n input sense voltage of 2V allows a wide range of currents Remote Sensing n and voltages to be monitored. Fast response makes the Load Protection n LTC6102 the perfect choice for load current warnings and Motor Control n shutoff protection control.
