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
PRODUCT OVERVIEW
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 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.

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).
