ADG609BR

The Analog Devices ADG609BR is a monolithic CMOS analog multiplexer featuring four differential channels. It is fully specified for ±5 V, +5 V, and +3 V power supplies. The device switches one of four differential inputs to a common differential output, controlled by 2-bit binary address lines A0 and A1. An enable input (EN) allows for disabling the device, switching all channels OFF.

Designed on an enhanced LC2MOS process, the ADG609BR offers low power dissipation, high switching speed, and low on-resistance. Each channel conducts equally well in both directions when ON, with an input signal range extending to the supplies. In the OFF condition, signal levels up to the supplies are blocked. The multiplexer exhibits break-before-make switching action, preventing momentary shorting when switching channels. It also features low charge injection for minimal transients when switching digital inputs.

This analog multiplexer is suitable for bus-controlled systems such as data acquisition systems, process controls, avionics, and ATEs due to its TTL-compatible address inputs. The ADG609BR is available in a 16-SOIC package and is designed for surface mount applications.

Key electrical characteristics include a typical on-resistance of 30 Ohms, fast switching times of 75ns (Ton) and 45ns (Toff), and low leakage current of 500 pA. Crosstalk is rated at -85dB at 100kHz.
