AD8465 Rail-to-Rail, Very Fast, 2.5 V to 5.5 V, Single-Supply LVDS Comparator
The AD8465 is a very fast comparator fabricated on the Analog Devices, Inc., proprietary XFCB2 process. This comparator is exceptionally versatile and easy to use. Features include an input range from VEE − 0.5 V to VCCI + 0.2 V, low noise, LVDS-compatible output drivers, and TTL/CMOS latch inputs with adjustable hysteresis and/or shutdown inputs.
The device offers 1.6 ns propagation delay with 1 ps rms random jitter (RJ). Overdrive and slew rate dispersion are typically less than 50 ps.

A flexible power supply scheme allows the devices to operate with a single 2.5 V positive supply and a −0.5 V to +2.7 V input signal range up to a 5.5 V positive supply with a −0.5 V to +5.7 V input signal range. Split input/output supplies, with no sequencing restrictions, support a wide input signal range with greatly reduced power consumption.
The LVDS-compatible output stage is designed to drive any standard LVDS input. The comparator input stage offers robust 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.
