MX-883

MX-826 Precision, High-Speed 8-Channel, Analog Multiplexers FEATURES • • • • • • 170ns maximum settling time to ±0.1% 225ns maximum settling time to ±0.01% 400ns maximum settling time to ±0.003% 8 Channels single-ended inputs 395mW power dissipation Small, 24-pin DDIP package ® ® INNOVATION and EXCELLENCE GENERAL DESCRIPTION The MX-826 is a precision, high-speed multiplexer characterized for 10, 12 and 14-bit applications. The performance benchmarks are its 225 nanoseconds maximum settling time to ±0.01% accuracy and its unprecedented specification of accuracy to ±0.003%. The MX-826 provides eight single-ended inputs. Channel addressing is done by a three-bit binary code and breakbefore-make switching assures that no two channels are ever momentarily shorted together. The MX-826 operates from ±15V and +5V power supplies. Models are available in two operating temperature ranges: 0 to +70°C and –55 to +125°C. MIL-STD-883 screening is optional.
