19-0300; Rev 0; 9/94 Precision, Low-Voltage Analog Switches ____________________________Features ♦ Single-Supply Operation (+3V to +15V) Bipolar-Supply Operation (±3V to ±8V) 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 35Ω), guaranteed to match to within 2Ω between channels and to remain flat over the specified analog signal range (4Ω max). They also offer low leakage (less than 250pA at +25°C and less than 2.5nA at +85°C) and fast switching (turn-on time less than 175ns and turn-off time less than 100ns). ♦ Pin-Compatible with DG401/DG403/DG405 ♦ Low On-Resistance, 20Ω Typical (35Ω Max) ♦ Guaranteed Matched On-Resistance Between Channels, <2Ω ♦ Guaranteed Flat On-Resistance over Specified Analog Signal Range, <4Ω ♦ Guaranteed Charge Injection, <5pC ♦ Guaranteed Off-Channel Leakage, <2.5nA at +85°C ♦ TTL/CMOS-Logic Compatible with 3V, 5V, ±3V, and ±5V Supplies ♦ Rail-to-Rail Analog Signal Handling Capability 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 (<10µW). 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. ______________Ordering Information PART ________________________Applications Sample-and-Hold Circuits Test Equipment Heads-Up Displays Audio Signal Routing Guidance and Control Systems Military Radios Communication Systems Battery-Operated Systems PBX, PABX TEMP.

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). D1 V+ MAX381 MAX383 MAX385 * * * * NO COM 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. 8 VD2 -5V * INTERNAL PROTECTION DIODES Figure 1.
