Maxim Integrated MAX4638ESE+ Analog Multiplexer

The Maxim Integrated MAX4638ESE+ is a high-performance, single-ended 8-channel analog multiplexer that operates with a single supply voltage ranging from +2.7V to +12V or dual supplies of ±2.7V to ±6V. This versatile component is designed for precision signal routing in applications such as data acquisition systems, test equipment, and communication devices.

The MAX4638ESE+ offers low on-resistance (100Ω max) and low channel-to-channel crosstalk and off-isolation, which makes it an excellent choice for multiplexing audio, video, or other high-frequency signals. The device's on-resistance is matched between channels to within 4Ω and is flat (5Ω max) over the specified signal range, ensuring minimal signal distortion and consistent performance across all channels.

This analog multiplexer also features fast switching speeds (t_TRANSITION = 250ns max), which is essential for applications that require rapid signal routing changes. Additionally, the MAX4638ESE+ is TTL/CMOS logic-compatible, allowing for easy integration into digital systems.

The MAX4638ESE+ comes in a compact 16-pin narrow SO package, making it suitable for space-constrained applications. Its extended temperature range (-40°C to +85°C) ensures reliable operation in various environmental conditions.

Key features of the MAX4638ESE+ include:

• Low Crosstalk: -86dB @ 1MHz
• Low Off-Isolation: -83dB @ 1MHz
• Single-Supply Operation: +2.7V to +12V
• Dual-Supply Operation: ±2.7V to ±6V
• Low Distortion: <0.02% (600Ω load)
• High Off-Resistance: 1MΩ min
• ESD Protection: >2000V per Method 3015.7

Whether you are designing an audio mixer, a video switcher, or a complex data acquisition system, the Maxim Integrated MAX4638ESE+ offers a reliable and efficient solution for your analog signal multiplexing needs. Its robust design and superior performance characteristics ensure that it can handle the most demanding applications with ease.
