10 kPa On-Chip Temperature

Compensated & Calibrated

Silicon Pressure Sensors

The MPX2010/MPXV2010G series silicon

piezoresistive pressure sensors provide a very

accurate and linear voltage output — directly

proportional to the applied pressure. These sensors

house a single monolithic silicon die with the strain

gauge and thin–film resistor network integrated on

each chip. The sensor is laser trimmed for precise

span, offset calibration and temperature

compensation.

Features

• Temperature Compensated over 0°C to +85°C

• Ratiometric to Supply Voltage

• Differential and Gauge Options

Application Examples

• Respiratory Diagnostics

• Air Movement Control

• Controllers

• Pressure Switching

Figure 1 shows a block diagram of the internal

circuitry on the stand–alone pressure sensor chip.

VOLTAGE OUTPUT versus

APPLIED DIFFERENTIAL PRESSURE

The output voltage of the differential or gauge sensor

increases with increasing pressure applied to the

pressure side (P1) relative to the vacuum side (P2).

Similarly, output voltage increases as increasing vacu-

um is applied to the vacuum side (P2) relative to the

pressure side (P1).
