The AD8468 is a fast comparator fabricated on XFCB2.0, an Analog Devices, Inc., proprietary process. This comparator is exceptionally versatile and easy to use. Features include an input range from −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 μA typical supply current.
A flexible power supply scheme allows the device to operate with a single 2.5 V positive supply with a −0.2 V to + 2.7 V input signal range and up to a 5.5 V positive supply with a −0.2 V to +5.7 V input signal range.
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 protection against large input overdrive, and the outputs do not phase reverse when the valid input signal range is exceeded. The AD8468 is available in a tiny 6-lead SC70 package with a single-ended output and a shutdown pin.
