Comlinear™ CLC2500
Dual, Ultra-fast Voltage Comparator
The Comlinear CLC2500 is a sub-nanosecond dual comparator with propagation delay variation less than 100ps from 5 to 50mV input overdrive voltage.
The input slew rate is 10 V/ns and the differential input stage has a commonmode input range of -2.5V to 4V.
The Comlinear CLC2500 has ECL-compatible complementary digital outputs
that are capable of driving 50Ω terminated transmission lines. The CLC2500
is ideally suited for automated test equipment (ATE) applications, high-speed
instrumentation, and peak detection.
