Each input channel consists of a static voltage reference generator. All channel outputs are capable of swinging rail-to-rail. The VCOM buffer is capable of driving a large peak current into highly capacitive loads while ensuring a rail-to-rail voltage swing. The ISL24002 is available in a 32 Ld thermal enhanced TQFN package. It is specified for operation over the -40°C to +85°C industrial temperature range. 4 Supply Voltage Range and Input Compatibility The ISL24002 is designed for operation on supply voltages from 5V to 18V. Each channel input pin and INPCOM can be driven rail-to-rail. Power Supply Bypassing and Printed Circuit Board Layout Good printed circuit board layout is necessary for optimum performance. A low impedance and clean analog ground plane should be used for the ISL24002. The traces from the ground pin to the ground plane must be very short. The thermal pad should be connected to the analog ground plane. Trace length should be as short as possible and all power supply pins must be well bypassed.
