The ADCMP608 is a fast comparator fabricated on XFCB2, an Analog Devices, Inc. proprietary process. This comparator is exceptionally versatile and easy to use. Features include an input range from VEE - 0.2 V to VCC + 0.2 V, low noise, TTL-/CMOScompatible output drivers, and shutdown inputs. The device offers 40 ns propagation delays driving a 15 pF load with 10 mV overdrive on 500 A typical supply current. A flexible power supply scheme allows the device to operate with a single +2.5 V positive supply and a -0.2 V to + 2.7 V input signal range up to a +5.5 V positive supply with a -0.2 V to +5.7 V input signal range.
