ADG444BRZ

The ADG444BRZ is a monolithic CMOS analog switch containing four independent single-pole, single-throw, normally-closed (SPST-NC) switches. It is designed on Analog Devices' enhanced LC2MOS process, which provides low power dissipation, high switching speed, and low on resistance. The device operates with a typical dual supply voltage of ±15V, and its analog signal range extends from VSS to VDD. The switch has a nominal on resistance of 70Ω, with flatness of 9Ω max and channel-to-channel matching of 3Ω max, ensuring good linearity when switching signals.

Switching times are 110ns max for turn-on and 60ns max for turn-off, making the part suitable for audio and video signal switching. Leakage current is typically 500pA, with a maximum of 3nA. The ADG444BRZ also features low charge injection (1pC typical, 6pC max) and break-before-make switching action. Crosstalk is -100dB at 1MHz, and the device is latch-up proof.

The operating temperature range is -40°C to +85°C. It is available in a 16-lead SOIC surface-mount package (16-SOIC, 0.154" width). Typical applications include audio and video switching, automatic test equipment, precision data acquisition, battery-powered systems, sample-and-hold circuits, and communication systems.
