ADCMP607:  Rail-to-Rail, Very Fast, 2.5 V to 5.5 V, Single-Supply CML Comparator in a 12-lead LSCFP Package

The ADCMP606 and ADCMP607 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 V_EE − 0.5 V to V_CCI + 0.2 V, low noise, CML-compatible output drivers, and TTL-/CMOS-compatible latch inputs with adjustable hysteresis and/or shutdown inputs.

The devices offer 1.25 ns propagation delay with 2.5 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 +2.7 V input signal range up to a +5.5 V positive supply with a −0.5 V to +5.7 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 swing 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, latch and programmable hysteresis features are also provided with a unique single-pin control option.

The ADCMP606 is available in a 6-lead SC70 package and the ADCMP607 is available in a 12-lead LFCSP package.
