Maxim Integrated MAX338ESE Analog Multiplexer

The MAX338ESE from Maxim Integrated is a high-performance, 8-channel single-ended analog multiplexer that operates from a single supply ranging from +4.5V to +30V or from dual supplies of ±4.5V to ±20V. This versatile component is designed for precision signal routing in various electronic applications such as data acquisition systems, test equipment, and communication devices.

Encased in a compact 16-pin narrow SO package, the MAX338ESE offers a low charge injection of 10pC (max) and low on-resistance of 100Ω (max), which remains flat over the specified signal range (5Ω max). This ensures excellent linearity and minimizes signal distortion, making it an ideal choice for handling audio signals and other sensitive analog data.

The device features a robust ESD protection of ±2000V, safeguarding the multiplexer against electrostatic discharges and enhancing its durability in harsh environments. The MAX338ESE also boasts a low crosstalk performance of -84dB and off-isolation of -74dB at 1MHz, which is critical for applications where signal integrity is paramount.

One of the key benefits of the MAX338ESE is its break-before-make switching action, which prevents momentary shorting when switching between channels. This feature is essential in preventing damage to sensitive circuit components and maintaining the integrity of the data being transferred.

For ease of use, the MAX338ESE can be controlled by digital inputs that are both TTL and CMOS compatible, allowing for seamless integration with a wide range of microcontrollers and digital interfaces. Its simple control logic facilitates straightforward implementation in various designs without the need for complex programming or additional hardware.

In summary, the Maxim Integrated MAX338ESE is a reliable and precise analog multiplexer that offers robust performance with its low on-resistance, low charge injection, and high ESD protection. Its compatibility with various supply voltages and logic levels makes it a versatile choice for designers looking to incorporate high-quality signal routing in their electronic systems.
