Aug 17, 2017 Overview The ISL71218MEVAL1Z evaluation platform is designed to evaluate the ISL71218M. The ISL71218M is a single supply, rail-to-rail output, dual amplifier with ground sensing inputs that allow the common-mode input voltage to swing 0.5V below the V- rail. The ISL71218M can operate from a single or dual supply with a 3V to 40V supply range. - Page 3 ISL71218MEVAL1Z 1.

ISL71218MEVAL1Z 2. Functional Description User-Selectable Options Component pads are included to enable a variety of user-selectable circuits to be added to the amplifier inputs, the VREF input, outputs, and the amplifier feedback loops. A voltage divider can be added to establish a power supply-tracking common-mode reference using the VREF input. -
