DG406, DG407 ANALOG SWITCHES AND MULTIPLEXERS - 1

16-Ch/Dual 8-Ch High-Performance CMOS Analog Multiplexers DESCRIPTION The DG406 is a 16 channel single-ended analog multiplexer designed to connect one of sixteen inputs to a common output as determined by a 4-bit binary address. The DG407 selects one of eight differential inputs to a common differential output. Break-before-make switching action protects against momentary shorting of inputs. An on channel conducts current equally well in both directions. In the off state each channel blocks voltages up to the power supply rails. An enable (EN) function allows the user to reset the multiplexer/demultiplexer to all switches off for stacking several devices. All control inputs, address (Ax) and enable (EN) are TTL compatible over the full specified operating temperature range. Applications for the DG406, DG407 include high speed data acquisition, audio signal switching and routing, ATE systems, and avionics. High performance and low power dissipation make them ideal for battery operated and remote instrumentation applications. Designed in the 44 V silicon-gate CMOS process, the absolute maximum voltage rating is extended to 44 V, allowing operation with ± 20 V supplies. Additionally single (12 V) supply operation is allowed. An epitaxial layer prevents latchup. For applications information please request documents 70601 and 70604.

DG406, DG407 Vishay Siliconix APPLICATIONS HINTS Sampling speed is limited by two consecutive events: the transition time of the multiplexer, and the settling time of the sampled signal at the output. For the DG406 then, at room temp and for 12-bit accuracy, using the maximum limits: tTRANS is given on the data sheet. Settling time at the load depends on several parameters: RDS(on) of the multiplexer, source impedance, multiplexer and load capacitances, charge injection of the multiplexer and accuracy desired. The settling time for the multiplexer alone can be derived from the model shown...
