Linear reveals current sense amplifier

Linear Technology has announced the LT6107, a military-plastic-grade (MP-grade) high-side current sense amplifier specified for operation from -55 to 150C.

As an MP-grade device, the LT6107 is intended to meet the demands of automotive, military and industrial, and other harsh environment applications.

It operates with common-mode voltages up to 36V.

The offset voltage is guaranteed to be less than 400 microvolts over temperature, and it can accept a full-scale differential input of 500mV, resulting in a minimum dynamic range of 1,250:1.

Over the full operating temperature range, input bias current is guaranteed to be no more than 130nA, essentially eliminating bias current as a source of error.

For handling fault conditions, the LT6107 can withstand common-mode voltages up to 44V and can respond to sudden signal changes within 3.5 microseconds.

Two external resistors set the amplifier gain, providing control of gain accuracy and drift, power consumption, response time and input/output impedance.

The LT6107 is also pin-compatible with Linear Technology's LT6106, LTC6101 and LTC6101HV, providing interchangeable current sense amplifiers with specific performance advantages.
