MAX4754/MAX4754A/MAX4755/MAX4756/MAX4756A 19-2942 Rev 1 11/06 0.5, Quad SPDT Switches in UCSP/QFN General Description Features The MAX4754/MAX4754A/MAX4755/MAX4756/MAX4756A Data and Audio-Signal Routing low on-resistance, analog switches operate from a single Low R (0.5 typ) Audio Switches ON +1.8V to +5.5V supply. The MAX4754/MAX4754A and 0.1 (typ) Channel-to-Channel Matching MAX4755 are dual, double-pole, double-throw (DPDT) switches. The MAX4756/MAX4756A are quad, single-pole 0.2 (typ) On-Resistance Flatness double-throw (SPDT) switches. They are configured to 0.035% (typ) THD route either audio or data signals. Improved Power-Supply Current for Non- The MAX4754/MAX4754A have four 0.5 SPDT switches for Rail-to-Rail Control Logic Inputs audio-signal routing and two logic control inputs. The (MAX4754A/MAX4756A) MAX4755 has four 0.5 SPDT switches (with two +1.8V to +5.5V Supply Range switches that have an additional 11 series resistor at the NC terminals). This allows users to drive an 8 Rail-to-Rail Signal Handling speaker as a 32 load (ear speaker). The MAX4756/ 16-Bump UCSP (2mm x 2mm) MAX4756A have four 0.5 SPDT switches controlled by Ordering Information one logic control input and an enable input (EN) to dis- able the switches.

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.
