MAX4530CAP

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4530CAP is a low-voltage CMOS analog multiplexer configured as an 8-channel mux in a 20-pin SSOP package. It operates from single supplies of +2V to +12V or dual supplies of ±2V to ±6V. The device features rail-to-rail signal handling, with on-resistance (RON) typically matching between channels to within 8Ω maximum and flatness of 150Ω maximum at ±5V supplies. Off-leakage current is specified at 1nA at +25°C and 50nA at +85°C. Digital inputs are TTL/CMOS compatible with thresholds of 0.8V and 2.4V. Switching times include turn-on and turn-off delays of 150ns and 120ns respectively at ±4.5V supplies.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CAP indicates the 20-lead SSOP package variant when sourcing. Confirm the temperature range matches the C designation (0°C to +70°C). Ensure compatibility with existing PCB footprints designed for standard SOIC or DIP packages due to pin-out similarities. Check for RoHS compliance status if required by project specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low-voltage operation and high channel density in a small footprint. Consider the 150Ω on-resistance limit when designing for low-impedance signal paths. Verify that the 1nA off-leakage specification meets the requirements for high-precision data acquisition. Ensure the supply voltage range aligns with the system's available power rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4530/MAX4531/MAX4532 family of low-voltage CMOS analog switches. The MAX4530 specifically provides an 8:1 multiplexer configuration, whereas the MAX4531 offers two 4:1 muxes and the MAX4532 provides three SPDT switches. All variants share pin compatibility and core electrical characteristics.
