What are the key features of MAX4638ETE+T?
- 3.5 Ω maximum on-resistance in single 8:1 or dual 4:1 analog multiplexer configuration, minimizing signal attenuation
- Wide supply range of +1.8 V to +5.5 V enabling operation from both 1.8 V and 3.3 V/5 V logic systems without level translation
- 16-pin QFN (4 x 4 mm, 0.75 mm height) package providing compact footprint for space-critical analog switching applications
What is MAX4638ETE+T used for?
The MAX4638ETE+T is used in data acquisition systems, automated test equipment, and communication line cards that require low-distortion 8-channel or dual 4-channel analog signal switching from a single supply between 1.8 V and 5.5 V. Its 3.5 Ω on-resistance makes it suitable for precision sensor multiplexing, audio routing, and instrumentation front-ends where signal fidelity must be maintained across -40°C to +85°C. The QFN package and tape-and-reel format suit volume production of portable medical monitors and industrial signal-conditioning modules.

Frequently Asked Questions
How does the 3.5 Ω on-resistance of the MAX4638ETE+T affect signal integrity in a precision 12-bit ADC input multiplexer?
The MAX4638ETE+T presents a maximum on-resistance of 3.5 Ω, which introduces a voltage drop proportional to current when driving a load. For a typical ADC input impedance of 10 kΩ, the 3.5 Ω series resistance causes less than 0.035% signal error, well within the linearity budget of a 12-bit ADC. To further minimize error, ensure the source impedance driving the MAX4638 is low relative to the 3.5 Ω on-resistance when accuracy demands are tight.
Can the MAX4638ETE+T operate from a 3.3 V single supply in an IoT sensor hub with 8 analog inputs?
Yes, the MAX4638ETE+T supports single-supply operation from +1.8 V to +5.5 V, making it fully compatible with a 3.3 V rail common in IoT and embedded systems. In single 8:1 mode it routes one of 8 analog inputs to a single output, covering all inputs of an 8-channel sensor hub. The -40°C to +85°C temperature range also matches typical IoT deployment environments, from industrial enclosures to outdoor sensor nodes.
What is the package footprint of the MAX4638ETE+T and how does it compare to a SOIC-16 for PCB area savings?
The MAX4638ETE+T uses a 16-pin QFN package measuring 4 x 4 mm with a 0.75 mm body height, compared to a standard SOIC-16 package that typically measures approximately 10 x 6 mm. Switching to the MAX4638ETE+T QFN reduces the connector footprint by roughly 73%, freeing significant board area on compact analog front-end PCBs in portable instruments, medical wearables, and IoT sensor nodes.
