MAX383CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX383CSE+T 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 low on-resistance of less than 35Ω, guaranteed matched within 2Ω between channels, and flatness under 4Ω over the signal range. Leakage current remains below 250pA at +25°C and 2.5nA at +85°C. Switching speeds include turn-on times under 175ns and turn-off times under 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 component authenticity by checking for the Maxim Integrated branding and the specific CSE package marking. Confirm the suffix indicates lead-free composition and RoHS compliance. Ensure the ordering code matches the exact temperature grade and package style required for your design specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when dual SPDT switching is required in space-constrained designs. It serves as a pin-compatible replacement for DG403 devices. Consider its low charge injection and high off-isolation for precision signal paths. Verify that the operating voltage range aligns with your system's power supply architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX381/MAX383/MAX385 family of precision analog switches. The MAX383 specifically provides two SPDT switches, whereas the MAX381 offers four SPST switches and the MAX385 provides two DPST switches. All share identical electrical characteristics and pinouts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states the device is pin-compatible with the Analog Devices DG403. Designers replacing legacy parts should verify that the substitute maintains the same SPDT topology and voltage ratings.
