MAX326CSE+

Introduction to MAX326CSE+

The MAX326CSE+ is an ultra-low power, low-voltage device used to interface analog switches, multiplexers, and demultiplexers, providing fast and reliable switching. The device operates in either a low quiescent current 400kHz I2C interface mode or a dedicated 11MHz SDA/SCL SPI interface mode. It is characterized by a maximum operating voltage of 0.85V, a minimum operating voltage of 0.3V, and a power-down/hold current of less than 1uA.MAX326CSE+ is an ideal choice for multiple applications such as sensor and actuator interfaces, audio/video switches, capacitive sensing, and digital control for isolated loads.

The Application Field of MAX326CSE+

MAX326CSE+ is suitable for a wide range of applications in multiplexers, analog switches and demultiplexers. It is ideal for digital control applications that require an ultra-low power, low-voltage solution.For example, it is commonly used in capacitive sensing applications to switch capacitors, allowing for higher sensitivity and lower noise levels. It is also used in sensor and actuator interfaces, audio/video switches, and digital control for isolated loads.

MAX326CSE+ Working Principle

The MAX326CSE+ works by connecting multiplexers, analog switches and demultiplexers in a variety of ways. The device has two interface modes- I2C and SDA/SCL SPI.In I2C mode, the device is used to monitor/control up to five CD4051 analog switches, providing fast and reliable switching. The device operates in a low quiescent current 400kHz I2C interface mode and provides power saving features such as auto-sense for active and inactive conditions,weak pull-up and programmable power-down current.In SDA/SCL SPI mode, the device is used to monitor/control up to three CD4051 analog switches. It provides operation at 11MHz, thus improving system performance. The device also has power saving features such as a programmable power-down current and an auto-sense that detects and switches between active/inactive conditions.
