Product Description

Product Details
The ADCMP551/ADCMP552/ADCMP553 are single supply, high speed comparators fabricated on Analog Devices’ proprietary XFCB process. The devices feature a 750 ps propagation delay with less than 150 ps overdrive dispersion. Dispersion, a measure of the difference in propagation delay under differing overdrive conditions, is a particularly important characteristic of high speed comparators. A separate programmable hysteresis pin is available on the ADCMP552.
A differential input stage permits consistent propagation delay with a common-mode range from –0.2 V to VCCI – 2.0 V. Outputs are complementary digital signals are fully compatible with PECL 10 K and 10 KH logic families. The outputs provide sufficient drive current to directly drive transmission lines terminated in 50 Ω to VCCO - 2 V. A latch input is included and permits tracking, track-and-hold, or sample-and-hold modes of operation. The latch input pins contain internal pullups that set the latch in tracking mode when left open.
The ADCMP551/ADCMP552/ADCMP553 are specified over the –40°C to +85°C industrial temperature range. The ADCMP551 is available in a 16-lead QSOP package; the ADCMP552 is available in a 20-lead QSOP package; and the ADCMP553 is available in an 8-lead MSOP package.
