LTC6101ACS5#TRPBF

The LTC6101/LTC6101HV from Analog Devices are high-voltage, high-side current sense amplifiers designed for versatile applications. They operate on supply voltages ranging from 4V to 60V for the LTC6101 and 5V to 100V for the LTC6101HV. These amplifiers feature a low offset voltage of 300µV maximum and low current consumption, with the LTC6101 consuming typically 375µA at 60V.

The internal circuitry converts the input voltage across an external sense resistor into an output current, enabling a small sense signal on a high common-mode voltage to be translated into a ground-referenced signal. This design reduces power loss in the shunt resistor. The devices offer a fast response time of 1µs and a maximum input sense voltage of 500mV, allowing for monitoring of a wide range of currents.

Packaged in a low-profile SOT-23 (ThinSOT™) package, the LTC6101 series is suitable for space-constrained applications. The wide operating supply range and high accuracy make them ideal for automotive, industrial, and power management systems requiring precise current shunt measurement.

Key features include configurable gain using two resistors, low input bias current of 170nA maximum, and a PSRR of 118dB minimum. The specified temperature range is -40°C to 125°C.
