Precision, Low-Voltage Analog Switches
_______________General Description
The MAX381/MAX383/MAX385 are precision, low-voltage analog switches. The single-pole single-throw MAX381 and double-pole single-throw MAX385 dual switches are normally open. The single-pole doublethrow MAX383 has two normally open and two normally closed poles. All three parts offer low on-resistance (less than 35), guaranteed to match to within 2 between channels and to remain flat over the specified analog signal range (4 max). They also offer low leakage (less than 250pA at +25C and less than 2.5nA at +85C) and fast switching (turn-on time less than 175ns and turn-off time less than 100ns). The MAX381/MAX383/MAX385 are fabricated with Maxim's low-voltage silicon-gate process for high system accuracy. Design improvements guarantee extremely low charge injection (<5pC) and low power consumption (<10W). These monolithic switches operate with a single positive supply (+3V to +15V) or with split supplies (3V to 8V) while retaining CMOS-logic input compatibility and fast switching. CMOS inputs provide reduced input loading.

Signals on NC, NO, COM, or IN exceeding V+ or V- are clamped by internal diodes. 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.

The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet. Guaranteed by design. RON = RON(max) - RON(min). On-resistance match between channels and flatness are guaranteed only with specified voltages. Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal range. Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at room temperature. See Figure 4. Off isolation = 20log10 VCOM/VNC or VNO, VCOM = output, VNC or NO = input to off switch. Between any two switches. See Figure 5. Leakage testing at single supply is guaranteed by testing with dual supplies. _______________________________________________________________________________________ 3

__________Applications Information
Operation with Supply Voltages Other than 5V
The MAX381/MAX383/MAX385 switches operate with 3.0V to 8V bipolar supplies and a +3V to +15V single supply. In either case, analog signals ranging from V+ to V- can be switched. The Typical Operating Characteristics graphs show the typical on-resistance variation with analog signal and supply voltage. The usual on-resistance temperature coefficient is 0.5%/C (typ).

Overvoltage Protection
Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence V+ on first, then V-, followed by the logic inputs, NO, or COM. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop above V-, but does not affect the devices' low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+ and V- should not exceed 17V. These protection diodes are not recommended when using a single 3V supply.
