Frequently Asked Questions
What supply voltage range does the MAX328EWE+T support?
The MAX328EWE+T operates from dual supplies ranging from ±5 V to ±18 V, with a nominal supply of ±15 V. This wide range allows it to interface seamlessly with standard ±15 V analog systems as well as lower-voltage ±5 V designs, giving engineers flexibility in system power architecture.
How does the MAX328EWE+T's leakage specification benefit high-impedance sensor circuits?
The ultra-low leakage current of the MAX328EWE+T, typically in the nA range, minimizes charge injection and signal degradation when switching high-impedance sensors. In a 8-channel data acquisition front-end with 1 MΩ source impedance, even 1 nA of leakage would introduce only 1 mV of offset error, preserving measurement accuracy across all 8 inputs.
For a 16-pin SOIC footprint, how does the MAX328EWE+T compare to DIP alternatives for compact PCB design?
The MAX328EWE+T in the 16-pin SOIC wide (300 mil) package occupies roughly 60% less board area than a through-hole DIP-16 equivalent, enabling denser PCB layouts in space-constrained instruments. The SOIC footprint also benefits from automated SMT assembly, reducing manufacturing cycle time and handling cost versus DIP packages.
When should designers choose the MAX328EWE+T over a lower-channel-count multiplexer?
Designers should choose the MAX328EWE+T when consolidating 8 analog signal sources into a single multiplexed ADC input, eliminating the need for multiple dual or quad switches. With 8 channels in one 16-pin SOIC device, the MAX328EWE+T reduces component count, simplifies routing of up to 8 input lines, and lowers BOM cost compared to using four 2-channel devices.
