Maxim Integrated MAX4639EUE+T Analog Multiplexer

The MAX4639EUE+T from Maxim Integrated is a high-performance, low-voltage, single 8-channel CMOS analog multiplexer that is designed to operate in a wide range of applications, from data acquisition systems to communication devices. This device is particularly well-suited for battery-powered and portable applications due to its low power consumption and compact package.

The MAX4639EUE+T operates with a single supply voltage ranging from +1.8V to +5.5V or dual supplies of ±2.7V to ±5.5V, making it versatile for various circuit designs. The low on-resistance (100 ohms max) of the multiplexer channels ensures minimal signal distortion, while the on-resistance match between channels (4 ohms max) and the flatness over the specified signal range (6 ohms max) contribute to the device's excellent analog performance.

This multiplexer also features fast switching speeds (t<sub>TRANS = 250ns max), which allows for quick signal routing and high bandwidth applications. The high off-isolation (-75dB at 1MHz) and crosstalk (-85dB at 1MHz) specifications ensure that signals are kept separate and noise is minimized during operation.

The MAX4639EUE+T comes in a 16-pin TSSOP package, offering a compact solution for space-constrained applications. Additionally, the device has an extended temperature range of -40°C to +85°C, which enables reliable performance in harsh environments.

Key features of the MAX4639EUE+T include:

• Single 8-Channel Multiplexer Configuration
• Low On-Resistance: 100 ohms max
• Low Crosstalk: -85dB at 1MHz
• High Off-Isolation: -75dB at 1MHz
• Fast Switching Times: t<sub>TRANS = 250ns max
• Single or Dual Supply Operation: +1.8V to +5.5V, ±2.7V to ±5.5V
• Extended Temperature Range: -40°C to +85°C
• Compact 16-Pin TSSOP Package

Overall, the MAX4639EUE+T is a reliable and efficient solution for designers looking to multiplex analog or digital signals in their systems with minimal signal degradation and power consumption.
