The MS4525DO is a small, ceramic based, PCB mounted
pressure transducer from TE Connectivity. The transducer is built
using our proprietary UltraStable™ process and the latest CMOS
sensor conditioning circuitry to create a low cost, high
performance digital output pressure (14bit) and temperature
(11bit) transducer designed to meet the strictest requirements
from OEM customers.
The MS4525DO is fully calibrated and temperature compensated
with a total error band (TEB) of less than 1.0% over the
compensated pressure range. The sensor operates from single
supply of either 3.3 or 5.0VDC and requires a single external
component for proper operation
The rugged ceramic transducer is available in side port, top port,
and manifold mount and can measure absolute, gauge,
differential, vacuum or compound pressure from 1 to 150psi. The
1/8” barbed pressure ports mate securely with 3/32” ID tubing.

Notes
1. Proper operation requires an external capacitor placed as shown in Connection Diagram. Output is not ratiometric to supply voltage.
2. The maximum deviation from a best fit straight line (BFSL) fitted to the output measured over the pressure range at 25C. Includes all
errors due to pressure non linearity, hysteresis, and non repeatability.
3. Total pressure error band includes all accuracy errors, thermal errors over the compensated temperature range and span and offset
calibration tolerances. For ideal sensor output with respect to input pressure and temperature, reference Transfer Function charts below.
TEB values are valid only at the calibrated supply voltage.
4. The deviation from a best fit straight line (BFSL) fitted to the output measured over the compensated temperature range.
5. For errors beyond the compensated temperature range, see Extended Temperature Multiplier chart below.
6. Start time to data ready is the time to get valid data after POR (power on reset). The time to get subsequent valid data is then specified
by the update time specification.
7. This product can be configured for custom OEM requirements, contact factory for lower power consumption or higher accuracy.

Description
Output is proportional to the difference between 0psiA (P min) and pressure
applied to Port 1.
Output is proportional to the difference between Port 1 and Port 2. Output
swings positive when Port 1> Port 2. Output is 50% of total counts when
Port 1=Port 2.
Output is proportional to the difference between 0psiG (Pmin) and Port 1.
Output swings positive when Port 1> Port 2.
Output is inversely proportional to the difference between -15psiG pressure
(Pmin) and pressure applied to Port 1.
Output is proportional to the difference between -15psiG pressure (Pmin) and
pressure applied to Port 1.
*Prange is equal to the maximum full scale pressure specified in the ordering information.

AVAILABLE OPTIONS
Gel Coat (-F Option)
The MS4525DO is designed for non-ionic and clean dry air applications. Select this option for added protection in
high humidity or slightly corrosive environments with the application of a silicone gel elastomer to sensor and
ASIC. For questions concerning media compatibility, contact the factory.
Low Power (-L Option)
Select this option for battery powered or handheld device applications. In this configuration, the sensor and
calibration microcontroller are powered down, drawing a current of ~ 0.6uA (Vs=5.0 VDC). When the master sends
a Read MR (measurement request) command (I2C or SPI); the sensor is “awaken” and begins the measurement
cycle; data is then placed onto the output registers. The sensor and calibration microcontroller are powered down
again, awaiting the Read DF (data fetch) command from the master.
