® ® MX-826 Precision, High-Speed 8-Channel Analog Multiplexers FEATURES PRODUCT OVERVIEW 170ns maximum settling time to ±0.1% 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%. 225ns maximum settling time to ±0.01% 400ns maximum settling time to ±0.003% 8 Channels single-ended inputs 395mW power dissipation The MX-826 provides eight single-ended inputs. Channel addressing is done by a three-bit binary code Small, 24-pin DDIP package and break-before-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.

(12 grams) TECHNICAL NOTES 1. Bypass the ±15V and +5V power supplies with a 1μF, 25V tantalum electrolytic capacitors in parallel with a 0.1μF ceramic capacitors. 2. Analog signals up to ±15V may be present while the MUX power supplies are off. 3. The absence of an RON specification or output leakage specification is related to the architecture of the switching network. The inputs see a constant 2.5k Ohm input impedance whether the channel is on or off. 4. Typical recovery time from an overvoltage condition of >±3V is approximately 200 nanoseconds from a negative overdrive and 700 nanoseconds from a positive overdrive. 5. Double-level multiplexing may be used to provide up to 64 channels (nine MX-826s required). Table 1.
