GENERAL DESCRIPTION
The ADCMP606/ADCMP607 are very fast comparators fabricated on Analog Devices’ proprietary XFCB2 process.
These comparators are exceptionally versatile and easy to use.
Features include an input range from VEE − 0.
5 V to VCC + 0.
5 V, low noise CML-compatible output drivers, and TTL-/CMOScompatible latch inputs with adjustable hysteresis and/or shutdown inputs.
The device offers 1 ns propagation delay with 2 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 +3.
0 V input signal range up to a +5.
5 V positive supply with a −0.
5 V to +6 V input signal range.
The ADCMP607 features split input/output supplies with no sequencing restrictions to support a wide input signal range with independent output level control and power savings.
The CML-compatible output stage is fully back-matched for superior performance.
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.
On the ADCMP607, high speed latch and programmable hysteresis features are also provided with a u...
