Frequently Asked Questions
What is the on-resistance and channel count of the MAX4781ETE+T multiplexer?
The MAX4781ETE+T provides 8 analog channels with a typical on-resistance of only 0.7 Ohm, enabling low-loss signal routing in data acquisition, instrumentation, and communications applications. Its single-ended multiplexer topology connects one of 8 inputs to a common output, reducing external component count.
Which supply voltage range does the MAX4781ETE+T support for low-voltage system designs?
The MAX4781ETE+T is designed for low-voltage operation, making it compatible with 3.3 V and 1.8 V digital supply rails commonly found in modern FPGAs, microcontrollers, and mixed-signal systems. This allows it to interface directly with low-voltage digital control logic without level-shifting, simplifying 8-channel signal routing circuit design.
How does the 16-pin LFCSP package affect PCB layout for the MAX4781ETE+T?
The 16-pin 3x3x0.75 mm LFCSP (Quad Flat No-Lead) package of the MAX4781ETE+T provides a small, leadless footprint with low parasitic inductance, which preserves high-speed switching performance across all 8 channels. The exposed die paddle also aids thermal dissipation, making it suitable for dense PCB layouts in portable instruments and compact industrial modules.
When would an engineer select the MAX4781ETE+T over a dual or quad-channel analog mux?
An engineer would select the MAX4781ETE+T when a design requires 8 single-ended analog channels in a single IC with 0.7 Ohm on-resistance rather than cascading multiple quad-channel switches, saving board space, reducing power consumption, and lowering BOM cost while maintaining high-speed channel switching for test, data acquisition, or audio signal routing applications.
