The AD8465 is a very fast comparator fabricated on the Analog A flexible power supply scheme al ows the devices to operate Devices, Inc., proprietary XFCB2 process. This comparator is with a single 2.5 V positive supply and a −0.5 V to +2.7 V input exceptional y versatile and easy to use. Features include an signal range up to a 5.5 V positive supply with a −0.5 V to +5.7 V input range from VEE − 0.5 V to VCCI + 0.2 V, low noise, LVDS- input signal range. Split input/output supplies, with no sequencing compatible output drivers, and TTL/CMOS latch inputs with restrictions, support a wide input signal range with greatly adjustable hysteresis and/or shutdown inputs. reduced power consumption. The device offers 1.6 ns propagation delay with 1 ps rms The LVDS-compatible output stage is designed to drive any random jitter (RJ). Overdrive and slew rate dispersion are standard LVDS input. The comparator input stage offers robust typically less than 50 ps. protection against large input overdrive, and the outputs do not phase reverse when the valid input signal range is exceeded. High speed latch and programmable hysteresis features are also provided in a unique single-pin control option. The AD8465 is available in a 12-lead LFCSP.
