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
2
O / ±5 mbar) and deliver outstanding accuracy
even at the bottom end of the measuring range.
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 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 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
Medical
HVAC
Automotive
Process automation
Burner control
OEM options
A variety of custom options can be implemented for high-
volume OEM applications. Ask us for more information.
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.

1
Unless otherwise noted, all sensor specifications are valid at 25°C with Vdd = 3.3 V and absolute pressure = 966 mbar.
2
The SDP50x/SDP51x sensors can detect negative differential pressures in the range of -500 to 0Pa. A negative differential pressure is represented
by a negative value. The accuracy of the negative differential pressure is not specified and might have significant inter-sensor variation.

See Application Note for response times with other resolutions, e.g. 1.3 ms with 10 bits.
5
With 12-bit resolution; includes repeatability and hysteresis.
6
Total accuracy/repeatability is a sum of zero-point and span accuracy/repeatability.
