MAX4523EEE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4523EEE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two normally closed and two normally open switches within a 16-pin QSOP package. The device operates with dual supplies from ±2V to ±6V or a single supply between +2V and +12V. On-resistance is typically 100Ω max with ±5V supplies, matched to 4Ω max across channels. Off-leakage current is 1nA at +25°C and 10nA at +85°C. Digital inputs have +0.8V and +2.4V logic thresholds for TTL/CMOS compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EEE' corresponds to the 16-pin QSOP package and -40°C to +85°C temperature range. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure pinout alignment with existing PCB layouts due to the specific NO/NC configuration of the MAX4523 variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mix of normally open and normally closed switching paths is required in a compact surface-mount form factor. Verify that the operating voltage range aligns with the system's power supply architecture. Consider the on-resistance flatness specifications if signal linearity over a wide voltage range is critical for the application design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4521/MAX4522/MAX4523 family of quad analog switches. The MAX4523 variant specifically provides two normally open and two normally closed switches, distinguishing it from the MAX4521 (all NC) and MAX4522 (all NO). The 'EEE' suffix denotes the commercial extended temperature grade housed in a QSOP package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include MAX4521EEE and MAX4522EEE, provided the specific NO/NC pin configuration matches the circuit requirements. Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
