MAXIM MAX4758, MAX4759 Technical data

General Description

The MAX4758/MAX4759 quad double-pole/doublethrow (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™).

ELECTRICAL CHARACTERISTICS

(V+ = +2.7V to +5.25V, TA= -40°C to +85°C, unless otherwise noted. Typical values are at V+ = 3V, TA= +25°C.) (Notes 2, 3)

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.

(V+ = 3V, TA= +25°C, unless otherwise noted.)

Note 2: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column. Note 3: UCSP packages are 100% tested at +25°C and limits across the full temperature range are guaranteed by correlation and

design. Thin QFN parts are 100% tested at +85°C and limits across the full temperature range are guaranteed by correlation and design.

Note 6: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
