The ADCMP600, ADCMP601, and ADCMP602 are very fast input signal range while still allowing independent output comparators fabricated on XFCB2, an Analog Devices, Inc. swing control and power savings. proprietary process. These comparators are exceptionally The TTL-/CMOS-compatible output stage is designed to drive versatile and easy to use. Features include an input range from up to 5 pF with full timing specs and to degrade in a graceful GND − 0.5 V to VCC + 0.2 V, low noise, TTL-/CMOS-compatible and linear fashion as additional capacitance is added. The output drivers, and latch inputs with adjustable hysteresis comparator input stage offers robust protection against large and/or shutdown inputs. input overdrive, and the outputs do not phase reverse when the The device offers 5 ns propagation delay with 10 mV overdrive valid input signal range is exceeded. Latch and programmable on 3 mA typical supply current. hysteresis features are also provided with a unique single-pin A flexible power supply scheme allows the devices to operate control option. with a single +2.5 V positive supply and a −0.5 V to +2.8 V The ADCMP600 is available in 5-lead SC70 and SOT-23 input signal range up to a +5.5 V positive supply with a −0.5 V packages, the ADCMP601 is available in a 6-lead SC70 package, to +5.8 V input signal range. Split input/output supplies with no and the ADCMP602 is available in an 8-lead MSOP package. sequencing restrictions on the ADCMP602 support a wide
