Current sense amplifier operates up to 150 deg C

Milpitas, Calif. — Linear Technology has introduced the military-plastic-grade (MP-grade) LT6107, a high-side current sense amplifier that operates over the temperature range of -55°C to 150°C. As a MP-grade device, the LT6107 is guaranteed and tested across the specified temperature range and is intended to meet the demands of automotive, military, industrial, and other harsh environment applications.

The LT6107 operates with common mode voltages up to 36 V. The offset voltage is guaranteed to be less than 400 uV over temperature and the LT6107 can accept a full-scale differential input of 500 mV, resulting in a minimum dynamic range of 1250:1. Over the full operating temperature range, input bias current is guaranteed to be no more than 130 nA, essentially eliminating bias current as a source of error, said Linear. For handling fault conditions, the LT6107 can withstand common mode voltages up to 44 V and can respond to sudden signal changes within 3.5 us.

Simple to use, 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's LT6106, LTC6101 and LTC6101HV, providing interchangeable current sense amplifiers with specific performance advantages.

Pricing: Starts at $2.35 each in quantities of 1,000.
Availability: In full production.
