ADCMP603

The ADCMP603 is a very fast comparator fabricated on XFCB2, an Analog Devices, Inc., proprietary process. This comparator is exceptionally versatile and easy to use. Features include an input range from V_EE − 0.5 V to V_CC + 0.2 V, low noise complementary TTL-/CMOS-compatible output drivers, and latch inputs with adjustable hysteresis and/or a shutdown input.

The device offers 3.5 ns propagation delay with 10 mV overdrive on 4 mA typical supply current.

A flexible power supply scheme allows the device 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 support a wide input signal range while still allowing independent output swing control and power savings. The device passes 4.5 kV HBM ESD testing and the absolute maximum ratings include current limits for all pins.

The complementary 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. High speed latch and programmable hysteresis features are also provided with a unique single-pin control option.

The ADCMP603 is available in a 12-lead LSCFP.
