36 V CURRENT SENSE AMPLIFIER
Linear Technology has announced the LT6106, a low cost, high side current sense amplifier that can resolve small differential signals from common mode voltages up to 36 V. With 250 √Ç¬µV(max) of input offset voltage and a full-scale differential input of 500 mV, the amplifier offers a dynamic range of 2000:1. The input bias current is guaranteed to be no more than 40 nA, essentially eliminating bias current as a source of error.
For handling fault conditions, the unit can withstand common mode voltages up to 44 V and can respond to signal changes within 3.5 √Ç¬µs. The operating temperature range is -40¬∞ to 125¬∞C.
