Fastest comparator - 4 ns prop delay, toggles at 150 MHz

26 September 2001 Analogue, Mixed Signal, LSI

Linear Technology has released the LT1715, a device it claims is the industry's fastest dual comparator. With 150 MHz toggle frequency and 4 ns propagation delay, the device meets or exceeds the performance requirements of a wide range of high-speed applications. The LT1715 supports supply voltages from 2,7 V to 10,5 V and can be operated using its independent analog and digital supply pins. It offers a wide input range that extends 100 mV below the negative rail and rail-to-rail outputs for compatibility with both 3 V and 5 V logic.

The LT1715's four independent supply pins permit the use of ±5 V analog supplies to accommodate large amplitude inputs while allowing a low-voltage digital supply for high-speed logic compatibility. The analog and digital supply pins can be tied together if desired. However, when used with separate supplies, the LT1715 is designed to tolerate any power sequencing at turn-on and turn-off. It includes internal hysteresis, which prevents oscillation and makes it easier to use than many other high-speed comparators. The device also features a pin-out that uses the power rails to shield the inputs from the potential parasitic effects of the fast switching output. This feature set makes the LT1715 ideal for use in a wide variety of high-speed signal processing applications from clock recovery to telecommunications, or high-speed test equipment.

The LT1715 is offered in the tiny 10-pin MSOP package.
