The MAX4706 is a normally closed (NC) switch and the MAX4707 is the normally open (NO) version. These switches provide 2 on-resistance (R ON) and 0.6 RON flatness with a +2.7V supply. These devices typically consume only 0.02A of quiescent current, making them suitable for use in low-power, portable applications. The MAX4706/MAX4707 feature low-leakage currents over the entire temperature range, TTL/CMOS-compatible digital logic, and excellent AC characteristics. The MAX4706/MAX4707 are offered in small 5-pin and 6-pin SC70 and 6-pin DFN packages.

MAX4706/MAX4707 Low-Voltage, 2, SPST, CMOS Analog Switches Detailed Description The MAX4706/MAX4707 SPST switches operate from a single supply ranging from 1.8V to 5.5V. The MAX4706 is a normally closed (NC) switch and the MAX4707 is the normally open (NO) version. These switches provide 3.5 on-resistance (RON) and 0.9 RON flatness with a +2.7V supply. These devices typically consume only 0.02A of quiescent current, making them suitable for use in low-power, portable applications. The MAX4706/MAX4707 feature low-leakage currents over POSITIVE SUPPLY MAX4706 MAX4707 D1 V+ Applications Information The MAX4706/MAX4707 operate from a single +1.8V to +5.5V supply. The MAX4706/MAX4707 accept bipolar input signals when V+ and GND are biased from bipolar supplies. For example, the switch accepts a 1VP-P input when V+ = 2V and GND = -2V. ESD-protection diodes are internally connected between each analog switch terminal and both V+ and GND. One of these diodes conducts if any analog signal is greater than V+ or less than GND (Figure 1). Virtually all analog leakage current is attributed to the ESD diodes. Each diode is biased by the analog signal and either V+ or GND. The ESD diodes' leakage currents vary as the signal changes. Power-Supply Sequencing and Overvoltage Protection N0 COM the entire temperature range, TTL/CMOS-compatible digital logic, and excellent AC characteristics. The MAX4706/MAX4707 are offered in small 5-pin and 6-pin SC70 and 6-pin DFN packages. Caution: Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to the device. 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. Vg GND D2 Figure 1.
