SDP600 Series (SDP6xx/5xx)

Low-cost Digital Differential Pressure Sensor

. Accuracy better than 0.2% FS near zero

. Digital output (I²C)

. Excellent repeatability, even below 10 Pa

. Calibrated and temperature compensated

. Excellent long-term stability

. Flow measurement in bypass configuration

Product Summary

The SDP600 sensor family is Sensirion’s series of digital

differential pressure sensors designed for high-volume

applications. They measure the pressure of air and non-

aggressive gases with superb accuracy and no offset drift.

The sensors cover a pressure range of up to ±500 Pa

(±2 inch H₂O / ±5 mbar) and deliver outstanding accuracy

even at the bottom end of the measuring range.

The outstanding performance of these sensors is based

on Sensirion’s patented CMOSens^®sensor technology,

which combines the sensor element, signal processing

and digital calibration on a tiny microchip. The differential

pressure is measured by a thermal sensor element using

flow-through technology. Compared with membrane-

based sensors, the SDP600 features an extended

dynamic range, better long-term stability, and improved

repeatability, especially near zero.

The SDP600 series operates from a 3.3V supply voltage

and features a digital 2-wire interface, which makes it easy

to connect directly to a microprocessor. The signal is

internally linearized and temperature compensated.

The well-proven CMOS technology is perfectly suited for

high-quality mass production and is the ideal choice for

demanding and cost-sensitive OEM applications.

Applications

Sensor chip

The SDP600 series features a fourth-generation silicon

sensor chip called SF04. In addition to a thermal mass

flow sensor element, the chip contains an amplifier, A/D

converter, EEPROM memory, digital signal processing

circuitry, and interface. The highly sensitive chip requires

only a minuscule amount of gas flow through the sensor.
