Here’s a detailed explanation of its pin function specifications, pinout, and circuit principles:
Pinout of ADG436BRZ (16 Pins):
Pin Number Pin Name Pin Type Function Description 1 S1 (Source) Input Channel 1 source connection for analog signal input or output. 2 D1 (Drain) Output Channel 1 drain connection, allows switching between source (S1) and drain (D1). 3 S2 (Source) Input Channel 2 source connection for analog signal input or output. 4 D2 (Drain) Output Channel 2 drain connection, allows switching between source (S2) and drain (D2). 5 S3 (Source) Input Channel 3 source connection for analog signal input or output. 6 D3 (Drain) Output Channel 3 drain connection, allows switching between source (S3) and drain (D3). 7 S4 (Source) Input Channel 4 source connection for analog signal input or output. 8 D4 (Drain) Output Channel 4 drain connection, allows switching between source (S4) and drain (D4). 9 GND Ground Ground connection. 10 INH (Inhibit) Input When this pin is high, it disables all switches. 11 VDD Power Positive supply voltage (typically +5V). 12 D5 (Drain) Output Channel 5 drain connection. 13 S5 (Source) Input Channel 5 source connection. 14 D6 (Drain) Output Channel 6 drain connection. 15 S6 (Source) Input Channel 6 source connection. 16 VSS Ground Negative supply voltage or ground reference.Functionality of Each Pin:
S1-S4 (Sources): These are the source pins for each channel. You apply the signal here. D1-D4 (Drains): These are the drain pins for each channel. The signal will be routed here depending on the switch's state. GND: This is the ground pin, used for providing a reference voltage to the device. INH (Inhibit): This pin controls the switching function of the chip. A high voltage at INH will inhibit the switching of the analog paths. VDD: The positive power supply pin, typically connected to a +5V or +3.3V source. VSS: The negative supply or ground connection for the device.Circuit Principle and Usage:
The ADG436BRZ is an analog switch, meaning it can selectively connect different signal paths. It uses MOSFET technology to enable low resistance switching with minimal distortion or signal loss. The device has four independent channels (S1-D1, S2-D2, S3-D3, and S4-D4), which can be independently controlled to connect a source to a drain. When the Inhibit pin is high, all channels are disabled.
