描述 Description

The ISL70100M is a radiation tolerant 40V current sense amplifier built on the Renesas proprietary PR40 Silicon-on-Insulator (SOI) process. The device has a wide power supply range of 2.7V to 40V. The input common-mode voltage is independent of the supply voltage and extends from -0.3V to 40.0V, making it ideal to use in both high-side and low-side applications.

The ISL70100M is a transconductance amplifier that monitors current using an external sense resistor and outputs a current proportional to the sensed voltage. The overall voltage gain is adjustable with a single resistor from the output to ground.

The amplifier has an extremely low offset voltage and input bias currents, making it ideal for precision sensing applications. It has a minimum bandwidth of 500kHz with a slew rate of 500µA/µs that makes it useful for current feedback in telemetry applications. When the part is powered down (V+ = V- = 0V), the sense pins (RS+, RS-) are high impedance to avoid loading the monitored circuit.

The part is available in a plastic 14Ld TSSOP package and operates across the temperature range of -55 °C to +125 °C.
