MAX383ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX383ESE is a precision, low-voltage analog switch featuring two single-pole double-throw (SPDT) poles. It operates with a single positive supply (+3V to +15V) or split supplies (±3V to ±8V). The device offers an on-resistance of less than 35Ω, guaranteed to match within 2Ω between channels and remain flat over the specified analog signal range (4Ω max). Leakage is less than 250pA at +25°C and 2.5nA at +85°C. Switching times include a turn-on time of less than 175ns and a turn-off time of less than 100ns. Charge injection is guaranteed below 5pC. It utilizes CMOS logic inputs compatible with 3V, 5V, ±3V, and ±5V supplies.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the -40°C to +85°C operating temperature range and 'SE' denotes the narrow SOIC package. Confirm RoHS compliance status if required by your manufacturing standards. Ensure the ordering part number matches the exact pin configuration and voltage requirements for your design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPDT switching is required in low-voltage environments. Verify that the maximum on-resistance of 35Ω meets your signal integrity needs. Ensure the supply voltage stays within the 3V to 15V single or ±3V to ±8V dual range. Check that the 175ns turn-on time fits your system timing constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX381/MAX383/MAX385 family of precision analog switches. While the MAX381 offers SPST functionality and the MAX385 provides DPST configuration, the MAX383 specifically delivers SPDT topology. All three share identical fabrication processes and core electrical characteristics, differing primarily in internal switch configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin-compatibility with DG401/DG403/DG405 devices. Verify that any substitute maintains the same 16-pin narrow SOIC footprint and electrical specifications regarding on-resistance and leakage currents.

Analog Switches, Multiplexers, Demultiplexers FAQ
