The LM161/LM361 is a very high speed differential input, complementary TTL output voltage comparator with improved characteristics over the SE529/NE529 for which it is a pin-for-pin replacement. The device has been optimized for greater speed performance and lower input offset voltage. Typically delay varies only 3 ns for over-drive variations of 5 mV to 500 mV. It may be operated from op amp supplies (±15V).

Complementary outputs having maximum skew are provided. Applications involve high speed analog to digital converters and zero-crossing detectors in disk file systems.

Evaluation board

AMP-PDK-EVM — Amplifier performance development kit evaluation module

The amplifier performance development kit (PDK) is an evaluation module (EVM) kit to test common operational amplifier (op amp) parameters and is compatible with most op amps and comparators. The EVM kit offers a main board with several socketed daughtercard options to fit package needs, allowing (...)
