ADG431BRZ

The ADG431BRZ is a monolithic CMOS device comprising four independently selectable SPST (Single-Pole Single-Throw) normally-closed switches. It is designed for precision analog switching applications requiring low on-resistance (24 Ohm max) and low leakage (250 pA max). The switches are controlled by TTL/CMOS logic inputs, with a logic low turning the switch on. This device is part of the ADG431/ADG432/ADG433 family and is a plug-in replacement for DG411/DG412/DG413. The ADG431BRZ offers fast switching times: ton 90 ns max, toff 60 ns max. It also features low charge injection (5 pC typical) and excellent crosstalk performance (-85 dB @ 1 MHz). The on-resistance profile is flat over the full analog input range, ensuring linearity and low distortion for audio signals. The device operates from a dual ±15V supply and can handle analog signal ranges up to 15V. It is available in a 16-lead SOIC package (0.154" width, 3.90mm) for surface mount assembly. The operating temperature range is -40°C to +85°C. Applications include audio and video switching, automatic test equipment, precision data acquisition, battery-powered systems, sample-and-hold circuits, and communication systems.
