MAX4758/MAX4759 19-3043 Rev 2 2/05 Quad DPDT Audio/Data Switches in UCSP/QFN General Description Features Data and Audio Signal Routing The MAX4758/MAX4759 quad double-pole/double- throw (DPDT) analog switches operate from a single Low On-Resistance (0.5) Audio Switches +1.8V to +5.5V supply. These switches feature low 0.2 On-Resistance Flatness 0.5 on-resistance for audio switching and a low 25pF 0.1 Channel-to-Channel Matching capacitance for data switching. Low-Capacitance (25pF) Data Switches (MAX4759) The MAX4758 has eight 0.5 on-resistance switches to 0.2ns Skew (MAX4759) switch audio signals. The MAX4759 has four 0.5 on- 0.03% THD resistance switches to route audio signals and four +1.8V to +5.5V Supply Range 25pF capacitance switches to route data signals. The Rail-to-Rail Signal Handling MAX4758/MAX4759 have four logic inputs to control the Tiny 36-Bump UCSP (3mm x 3mm) switches in pairs. 36-Pin Thin QFN (6mm x 6mm) The MAX4758/MAX4759 are available in a small 36-pin Ordering Information (6mm x 6mm) thin QFN and 36-bump (3mm x 3mm) chip-scale package (UCSP).

Limit forward-diode current to maximum current rating. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS (V+ = +2.7V to +5.25V, T = -40C to +85C, unless otherwise noted.
