SDP600 Series (SDP6xx/5xx)
Low-cost Digital Differential Pressure Sensor
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 H
even at the bottom end of the measuring range.
The SDP600 series operates from a 3.3 Vdc supply
voltage and features a digital 2-wire interface, which
makes it easy to connect directly to a microprocessor. The

Low pressure versions SDP600/610-125Pa and
SDP600/610-25Pa are suited to measure very low and
ultra low differential pressure.
Low power versions (SDP606/SDP616) are developed
especially for low power battery operation.

The outstanding performance of these sensors is based
on Sensirion’s patented CMOSens
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 well-proven CMOS technology is perfectly suited for
high-quality mass production and is the ideal choice for
demanding and cost-sensitive OEM 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.
