Description

The MS5525DSO from TE Connectivity is a compact, surface-mount digital pressure sensor built on robust MEMS technology. It provides absolute, gauge, or differential pressure measurement with a high-resolution 24-bit delta-sigma analog-to-digital converter (ADC) integrated on-chip. The sensor outputs fully calibrated digital data for both pressure and temperature, simplifying system design and reducing development time.

Engineered for reliability in demanding conditions, the device operates from a 1.8V to 3.6V supply, featuring ultra-low power consumption and conversion times as fast as 1 ms. This combination of speed, accuracy, and low power makes it ideal for real-time monitoring in HVAC systems, medical instrumentation, industrial process control, and portable data loggers.

Frequently Asked Questions

What is the supply voltage range for the MS5525DSO sensor?

The MS5525DSO operates from a 1.8V to 3.6V DC supply, making it directly compatible with standard 3.3V microcontroller logic levels without requiring a level shifter. This low-voltage range is optimized for battery-powered and portable embedded systems.

Does this sensor require external calibration?

No, the MS5525DSO is factory calibrated. It stores individual calibration coefficients (C1-C6) in its onboard PROM, which are used to calculate highly accurate pressure and temperature values digitally, eliminating the need for end-user calibration.

How do I communicate with the MS5525DSO using I2C or SPI?

The sensor supports both I2C (up to 400 kHz) and SPI (Mode 0, 3) interfaces, selectable via the PS pin. For I2C, the default 7-bit slave address is 0x76. The datasheet provides detailed command sequences for initiating conversions and reading pressure and temperature data registers.

What is the difference between absolute, gauge, and differential pressure measurement modes?

The MS5525DSO can be configured for different pressure types based on its port configuration. Absolute pressure is measured relative to a vacuum, gauge pressure relative to ambient atmosphere, and differential pressure between two applied pressures. The specific model variant defines its default measurement type.

What is the typical response time or conversion rate?

The sensor offers programmable conversion times, with the fastest setting being approximately 1 ms for a pressure reading. This fast response enables real-time monitoring and control in dynamic systems such as pneumatic controls or medical ventilation equipment.
