19-2942; Rev 0; 8/03 0.5Ω, Quad SPDT Switches in UCSP/QFN The MAX4754/MAX4755/MAX4756 low on-resistance, analog switches operate from a single +1.8V to +5.5V supply. The MAX4754 and MAX4755 are dual, doublepole, double-throw (DPDT) switches. The MAX4756 is a quad, single-pole double-throw (SPDT) switch. They are configured to route either audio or data signals. The MAX4754 has four 0.5Ω SPDT switches for audiosignal routing and two logic control inputs. The MAX4755 has four 0.5Ω SPDT switches (with two switches that have an additional 11Ω series resistor at the NC terminals). This allows users to drive an 8Ω speaker as a 32Ω load (ear speaker). The MAX4756 has four 0.5Ω SPDT switches controlled by one logic control input and an enable pin (EN) to disable the switches.

The devices are fully specified for nominal 3V applications. The MAX4754 DPDT switch has two logic control inputs with each input controlling two SPDT switches. Each switch has a 0.5Ω on-resistance in the NO and NC terminals making it ideal for switching audio signals. The MAX4755 DPDT switch also has four 0.5Ω SPDT switches with the switch pairs 1 and 2 adding an 11.5Ω series resistor to the NC terminal. This feature allows the user to drive an 8Ω speaker as a 32Ω load, allowing it to be used as an ear speaker. Two logic control inputs are used to control the four switches. The MAX4756 has four 0.5Ω SPDT switches controlled by one logic control input (INA) and EN input to disable the switches. Applications Information Analog Signal Levels Analog signal inputs over the full voltage range (0V to V+) are passed through the switch with minimal change in on-resistance (see the Typical Operating Characteristics). The switches are bidirectional so NO_, NC_, and COM_ can be either inputs or outputs. Power-Supply Bypassing Power-supply bypassing improves noise margin and prevents switching noise from propagating from the V+ supply to other components. A 0.1µF capacitor connected from V+ to GND is adequate for most applications. UCSP Applications Information For the latest application details on UCSP construction, dimensions, tape carrier information, printed circuit board techniques, bump-pad layout, and recommended reflow temperature profile, as well as the latest information on reliability testing results, go to the Maxim website at www.maxim-ic.com/ucsp for the Application Note: UCSP—A Wafer-Level Chip-Scale Package. Digital Control Inputs The MAX4754/MAX4755/MAX4756 logic inputs accept up to +5.5V regardless of the supply voltage. For example, with a +3.3V supply IN_ can be driven low to GND and high to +5.5V, which allows mixed logic levels in a system. Driving the control logic inputs rail-torail also minimizes power consumption. For a +3V supply voltage, the logic thresholds are 0.5V (low) and 1.4V (high). For the MAX4756, drive EN low to enable the COM_. When EN is high, COM _ is high impedance. 8 _______________________________________________________________________________________ 0.5Ω, Quad SPDT Switches in UCSP/QFN MAX4754 MAX4755 MAX4756 V+ V+ COM_ NO_ OR NC_ VN_ LOGIC INPUT V+ 0V VOUT RL t OFF CL IN_ VOUT GND LOGIC INPUT SWITCH OUTPUT ( 0.9 x V0UT 0.9 x VOUT 0V t ON CL INCLUDES FIXTURE AND STRAY CAPACITANCE.
