1 / 12 page _______________General Description The MAX381/MAX383/MAX385 are precision, low-volt- age analog switches. The single-pole single-throw MAX381 and double-pole single-throw MAX385 dual switches are normally open. The single-pole double- throw MAX383 has two normally open and two normally closed poles. All three parts offer low on-resistance (less than 35 Ω), guaranteed to match to within 2Ω between channels and to remain flat over the specified analog signal range (4 Ω max). They also offer low leak- age (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). The MAX381/MAX383/MAX385 are fabricated with Maxim’s low-voltage silicon-gate process for high sys- tem accuracy. Design improvements guarantee extremely low charge injection (<5pC) and low power consumption (<10µW). These monolithic switches operate with a single posi- tive 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. ________________________Applications Sample-and-Hold Circuits Military Radios Test Equipment Communication Systems Heads-Up Displays Battery-Operated Systems Audio Signal Routing PBX, PABX Guidance and Control Systems ____________________________Features o Single-Supply Operation (+3V to +15V) Bipolar-Supply Operation (±3V to ±8V) o Pin-Compatible with DG401/DG403/DG405 o Low On-Resistance, 20 Ω Typical (35Ω Max) o Guaranteed Matched On-Resistance Between Channels, <2 Ω o Guaranteed Flat On-Resistance over Specified Analog Signal Range, <4 Ω o Guaranteed Charge Injection, <5pC o Guaranteed Off-Channel Leakage, <2.5nA at +85°C o TTL/CMOS-Logic Compatible with 3V, 5V, ±3V, and ±5V Supplies o Rail-to-Rail Analog Signal Handling Capability ______________Ordering Information Precision, Low-Voltage Analog Switches ________________________________________________________________ Maxim Integrated Products 1 MAX383 LOGIC IN COM 0 1 NC NO TOP VIEW MAX381 LOGIC IN SWITCH 0 1 OFF ON MAX385 LOGIC IN COM, NO 0 1 OFF ON 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 NO1 IN1 V- GND NO3 COM3 N.C.
