Maxim Integrated MAX305CSE - Precision Analog Multiplexer

The Maxim Integrated MAX305CSE is a high-performance, 8-channel single-ended analog multiplexer. This precision device is designed to operate with a single supply voltage ranging from +4.5V to +30V or dual supplies of ±4.5V to ±20V, making it versatile for a wide array of applications. The MAX305CSE is available in a compact 16-pin narrow SO package, ensuring a minimal footprint on your circuit board.

Featuring low charge injection of less than 10pC, low power consumption, and ESD protection greater than 2000V per Method 3015.7, the MAX305CSE offers reliable performance for critical applications. It also boasts a low leakage current over the full temperature range, which is essential for maintaining signal integrity in precision circuits.

The MAX305CSE is an ideal choice for use in data acquisition systems, battery-operated equipment, sample-and-hold circuits, and audio signal routing, among other applications. Its high off-isolation of -80dB at 1MHz ensures minimal crosstalk between channels, which is crucial for maintaining the purity of the signal in multiplexed environments.

This analog multiplexer is designed with break-before-make switching action, which prevents momentary shorting when switching between channels. The device also features a 44Ω (max) on-resistance with a very low on-resistance matching between channels of less than 2.5Ω. This consistency guarantees that each channel behaves uniformly, providing predictable and stable performance across all switch positions.

The MAX305CSE is controlled via a simple digital interface, compatible with TTL and CMOS logic levels, thus allowing easy integration with microcontrollers and other digital systems. With its robust design and reliable performance, the Maxim Integrated MAX305CSE is a standout choice for designers looking to implement an efficient and precise analog multiplexing solution in their projects.
