The MAX4758/MAX4759 quad double-pole/double-throw (DPDT) analog switches operate from a single +1.8V to +5.5V supply. These switches feature low 0.5Ω on-resistance for audio switching and a low 25pF capacitance for data switching. The MAX4758 has eight 0.5Ω on-resistance switches to switch audio signals. The MAX4759 has four 0.5Ω on-resistance switches to route audio signals and four 25pF capacitance switches to route data signals. The MAX4758/MAX4759 have four logic inputs to control the switches in pairs. The MAX4758/MAX4759 are available in a small 36-pin (6mm x 6mm) thin QFN and 36-bump (3mm x 3mm) chip-scale package (UCSP™).
The MAX4758 and MAX4759 are quad double‑pole/double‑throw analog switches designed for audio and data signal routing. They operate from a single +1.8 V to +5.5 V supply and feature low on‑resistance (0.5 Ω for audio) and low capacitance (25 pF for data), making them suitable for high‑fidelity audio and fast data applications.
Both devices are available in a 36‑bump chip‑scale package (UCSP) and a 36‑pin thin QFN. The datasheet provides detailed electrical characteristics, timing diagrams, pin descriptions, and package information for designers.
