The device operates from +\/-15V dual supplies, providing an analog signal range of +\/-15V for industrial and instrumentation applications. The 280-ohm typical on-resistance and 40-ohm on-resistance flatness minimize signal distortion. The 0.1 nA leakage current at 25C preserves signal integrity in high-impedance circuits. The 200 ns switching time supports moderate-speed scanning applications. The break-before-make switching prevents momentary short-circuiting between channels. The EN pin enables or disables all channels simultaneously. The ADG508A is the 8-channel single-ended version; the ADG509A is the 4-channel differential version in the same SOIC-16 package.","working_principle":"The ADG508AKRZ uses a DMOS (double-diffused MOS) switching structure optimized for high-voltage analog signal handling. Each switch consists of an N-channel and P-channel MOSFET in parallel (transmission gate configuration), which provides a relatively constant on-resistance across the full analog signal range. The 3-bit address input (A0, A1, A2) is decoded by an internal logic circuit that drives the gate of the selected switch pair. The EN pin, when LOW, opens all switches regardless of the address. The break-before-make timing is ensured by an internal delay that opens the currently closed switch before closing the newly selected switch, preventing channel-to-channel crosstalk and momentary shorts. The +\/-15V supplies bias the internal level shifters that translate the TTL\/CMOS-compatible address and enable logic levels to the gate voltages required to switch the +\/-15V analog signals. The 0.1 nA leakage is achieved through careful layout and junction isolation of the switch structures.","pin_description":"
