Its 250 Ohm max on-resistance and 1 pC charge injection keep signal distortion low in sample-and-hold or audio routing paths. The switch handles dual supplies from ±1V to ±6V, so it can pass bipolar signals without external level translation. Switching is fast enough for most multiplexed data-acquisition front-ends: 150 ns turn-on, 100 ns turn-off. Off-state leakage stays under 1 nA, and channel capacitance is 3 pF each side. This is a commercial-temperature part (0°C to 70°C), suited for bench instruments, telecom line cards, and industrial control panels where the ambient stays within that range. ## Active lifecycle — no LTB risk for production BOMs The MAX4503CUK+T carries an Active product status and is ROHS3 compliant. For new designs or ongoing production, this part does not introduce obsolescence risk.","metaTitle":"MAX4503CUK+T Analog Switch, SPST-NO, 250 Ohm, SOT-23-5","metaDescription":"MAX4503CUK+T single SPST-NO analog switch, 250 Ohm max on-resistance, 150 ns switching, dual ±1V to ±6V supply.
