Maxim MAX9690MJA-4, MAX9690ESA, MAX9690CSA, MAX9690CPA-4, MAX9690CJA Datasheet
_______________General Description
The MAX9690 is an ultra-fast ECL comparator manufactured with a high-frequency bipolar process (fT= 6GHz)
capable of very short propagation delays. This design
maintains the excellent DC matching characteristics normally found only in slower comparators. The MAX9690 is
similar in function to the MAX9685, except the latchenable input is eliminated.
The MAX9690 is pin-compatible with the CMP-08 but
exceeds the AC characteristics of that device.
The MAX9690 has differential inputs and complementary outputs that are fully compatible with ECL-logic levels. Output current levels are capable of driving 50Ω
terminated transmission lines. The ultra-fast operation
makes signal processing possible at frequencies in
excess of 600MHz.

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(V+ = +5V, V- = -5.2V, RL= 50Ω, VT= -2V, TA= +25°C, unless otherwise noted.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
