AD7503JQ

AD7503JQ Description

The AD7503JQ is an obsolete 8:1 multiplexer/demultiplexer integrated circuit manufactured by Analog Devices Inc. This through-hole mounted device is housed in a 16-pin ceramic dual in-line package (16CERDIP) and is designed for applications requiring reliable and efficient signal routing. The AD7503JQ operates with a dual supply of voltage ±15V, ensuring compatibility with a wide range of analog systems. It features a maximum on-state resistance (Ron) of 300 ohms, which minimizes signal attenuation and power loss during operation. The switch time for both turn-on (Ton) and turn-off (Toff) is a maximum of 800 nanoseconds, providing fast and responsive signal switching.

The AD7503JQ also boasts a channel-to-channel matching of 12 ohms, ensuring consistent performance across all channels. The channel capacitance is rated at 5 pF for the source (CS(off)) and 30 pF for the drain (CD(off)), which helps maintain signal integrity and reduce crosstalk. With a moisture sensitivity level (MSL) of 1, the AD7503JQ is suitable for a variety of environmental conditions without the need for special handling or storage precautions.
