The ADCMP600, ADCMP601, and ADCMP602 are very fast comparators fabricated on XFCB2, an Analog Devices, Inc. proprietary process. These comparators are exceptionally versatile and easy to use. Features include an input range from GND − 0.5 V to VCC + 0.2 V, low noise, TTL-/CMOS-compatible output drivers, and latch inputs with adjustable hysteresis and/or shutdown inputs. The device offers 5 ns propagation delay with 10 mV overdrive on 3 mA typical supply current. A flexible power supply scheme allows the devices to operate with a single +2.5 V positive supply and a −0.5 V to +2.8 V input signal range up to a +5.5 V positive supply with a −0.5 V to +5.8 V input signal range. Split input/output supplies with no sequencing restrictions on the ADCMP602 support a wide input signal range while still allowing independent output swing control and power savings. The TTL-/CMOS-compatible output stage is designed to drive up to 5 pF with full timing specs and to degrade in a graceful and linear fashion as additional capacitance is added. 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. Latch and programmable hysteresis features are also provided with a unique single-pin control option. The ADCMP600 is available in 5-lead SC70 and SOT-23 packages, the ADCMP601 is available in a 6-lead SC70 package, and the ADCMP602 is available in an 8-lead MSOP package.
