GENERAL DESCRIPTION PRODUCT HIGHLIGHTS
The ADG508A and ADG509A are CMOS monolithic analog 1. Single-/Dual-Supply Specifications with a Wide Tolerance. multiplexers with eight channels and dual four channels, respec- The devices are specified in the 10.8 V to 16.5 V range for tively. The ADG508A switches one of eight inputs to a common both single and dual supplies. output, depending on the state of three binary addresses and an 2. Extended Signal Range. The enhanced LC2MOS processing enable input. The ADG509A switches one of four differential results in a high breakdown and an increased analog signal inputs to a common differential output, depending on the state range of VSS to VDD. of two binary addresses and an enable input. Both devices have 3. Break-Before-Make Switching. Switches are guaranteed TTL and 5 V CMOS logic-compatible digital inputs. break-before-make so that input signals are protected The ADG508A and ADG509A are designed on an enhanced against momentary shorting. LC2MOS process that gives an increased signal capability of VSS 4. Low Leakage. Leakage currents in the range of 20 pA make to VDD and enables operation over a wide range of supply voltages. these multiplexers suitable for high precision circuits. The devices can comfortably operate anywhere in the 10.8 V to 16.5 V single- or dual-supply range. These multiplexers also feature high switching speeds and low RON.
