Exar Wide Input Voltage JFET Comparators

Cadeka Wide Input Voltage JFET Comparators

Exar Wide Input Voltage JFET Comparators are a high-speed, wide common mode voltage, JFET input, dual comparators. These Wide Input Voltage JFET Comparators are designed for applications that measure critical timing parameters in which wide common mode input voltages are required. Propagation delays for Exar's Wide Input Voltage JFET Comparators are constant for overdrives greater than 200 mV for the SPT9691 and 50mV for the SPT9693. JFET inputs for these Wide Input Voltage JFET Comparators reduce the input bias currents to the nanoamp level, eliminating the need for input drivers and buffers in most applications. Exar's Wide Input Voltage JFET Comparators have differential analog inputs and complementary logic outputs compatible with ECL systems.
