GENERAL DESCRIPTION The ADCMP604 and ADCMP605 are very fast comparators fabricated on Analog Devices, Inc.’s, proprietary XFCB2 process. This family of comparators is exceptionally versatile and easy to use. Features include an input range from VEE − 0.5 V to VCC + 0.2 V, low noise, LVDS-compatible output drivers, and TTL/CMOS latch inputs with adjustable hysteresis and/or shutdown inputs. The devices offer 1.5 ns propagation delays with 1 ps rms random jitter (RJ). Overdrive and slew rate dispersion are typically less than 50 ps. A flex...
