The ADCMP609 is a fast comparator fabricated on XFCB2, an Analog Devices, Inc. proprietary process. These comparators are exceptionally versatile and easy to use. Features include an input range from V_EE 0.2 V to V_CC + 0.2 V, low noise, TTL-/ CMOS-compatible output drivers, and adjustable hysteresis and/or shutdown inputs.

The device offers 40 ns propagation delay driving a 15 pF load with 10 mV overdrive on 500 A typical supply current.

A flexible power supply scheme allows the devices to operate with a single +2.5 V positive supply and a 0.2 V to +3.0 V input signal range 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 comparator¡¯s input stage offers robust protection against large input overdrive, and the outputs do not phase reverse when the valid input signal range is exceeded. A programmable hysteresis features is also provided.

The ADCMP609, available in an 8-lead MSOP package, features a shutdown pin and hysteresis control.
