ADCMP608

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-/CMOS-compatible 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.

The TTL-/CMOS-compatible output stage is designed to drive up to 15 pF with full rated timing specifications and to degrade in a graceful and linear fashion as additional capacitance is added. The input stage of the comparator offers robust protec-tion against large input overdrive, and the outputs do not phase reverse when the valid input signal range is exceeded.
The ADCMP608 is available in a tiny 6-lead SC70 package with a single-ended output and a shutdown pin.

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.
