UM4684 0.5Ω Low-Voltage Dual SPDT Analog Switch UM4684H CSP10 2.0×1.5 UM4684EEUE MSOP10 General Description The UM4684 is a sub 1Ω (0.5Ω at 2.7V) dual SPDT analog switch designed for low voltage applications. The UM4684 has on-resistance matching(less than 0.05Ω at 2.7V) and flatness (less than 0.2Ω at 2.7V) that are guaranteed over the entire voltage range. Additionally, low logic thresholds make the UM4684 an ideal interface to low voltage DSP control signals. The UM4684 has fast switching speed with break-before-make guaranteed. In the ON condition, all switching elements conduct equally in both directions. OFF-isolation and crosstalk is -69dB at 100kHz. The UM4684 is built on high-density low voltage CMOS process, and contains the additional benefit of 2000V ESD protection. As a committed partner to the community and the environment, Union manufactures this product with lead (Pb)-free device terminations.

For example, with a +3.3V supply, IN_ may be driven low to GND and high to 5.5V. Driving IN_ rail-to-rail minimizes power consumption. Logic levels for a +1.8V supply are 0.5V (low) and 1.4V (high). Analog Signal Levels Analog signals that range over the entire supply voltage (V+ to GND) is passed with very little change in on-resistance (see Typical Operating Characteristics). The switches are bidirectional, so the NO_, NC_, and COM_ pins can be either inputs or outputs. Caution Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to devices. Proper power-supply sequencing is recommended for all CMOS devices. Always apply V+ before applying analog signals, especially if the analog signal is not current limited. If this sequencing is not possible, and if the analog inputs are not current limited to <20mA, add a small signal diode (D1) as shown in Figure 6. Adding a protection diode reduces the analog range to a diode drop (about 0.7V) below V+ (for D1). RON increases slightly at low supply voltages. Maximum supply voltage (V+) must not exceed +6V. Protection diode D1 also protects against some over voltage situations. No damage will result on Figure 6’s circuit if the supply voltage is below the absolute maximum rating applied to an analog signal pin.
