Product Details

The ADG526A and ADG527A are CMOS monolithic analog multiplexers with 16 single channels and dual 8 channels, respectively. On-chip latches facilitate microprocessor interfacing. 

The ADG526A switches one of 16 inputs to a common output, depending on the state of four binary addresses and an enable input. The ADG527A switches one of eight differential inputs to a common differential output, depending on the state of three binary addresses and an enable input. Both devices have TTL and 5 V CMOS logic-compatible digital inputs. 

The ADG526A and ADG527A are designed on an enhanced LC2MOS process that gives an increased signal capability of VSS to VDD and enables operation over a wide range of supply voltages. 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


  1. Single- or Dual-Supply Specifications with a Wide Tolerance. The devices are specified in the 10.8 V to 16.5 V range for both single and dual supplies.
  2. Easily Interfaced. The ADG526A and ADG527A can be easily interfaced with microprocessors. The WR signal latches the state of the address control lines and the enable line. The RS signal clears both the address and enable data in the latches, resulting in no output (all switches off). RS can be tied to the microprocessor reset pin.
  3. Extended Signal Range. The enhanced LC2MOS processing results in a high breakdown and an increased analog signal range from VSS to VDD.
  4. Break-Before-Make Switching. Switches are guaranteed break-before-make so that input signals are protected against momentary shorting.
  5. Low Leakage. Leakage currents in the range of 20 pA make these multiplexers suitable for high precision circuits.
