MPX4250D

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MPX4250D/D MPX4250D Integrated Silicon Pressure Sensor On-Chip Signal Conditioned, Temperature Compensated and Calibrated The MPX4250D series piezoresistive transducer is a state–of–the–art monolithic silicon pressure sensor designed for a wide range of applications, but particularly those employing a microcontroller or microprocessor with A/D inputs. This patented, single element transducer combines advanced micromachining techniques, thin–film metallization, and bipolar processing to provide an accurate, high level analog output signal that is proportional to the applied pressure. Features Differential and Gauge Applications Only 1.4% Maximum Error Over 0° to 85°C Ideally suited for Microprocessor Interfacing Patented Silicon Shear Stress Strain Gauge Temperature Compensated Over – 40° to +125°C Offers Reduction in Weight and Volume Compared to Existing Hybrid Modules Durable Epoxy Unibody Element VS 3 SERIES OPERATING OVERVIEW INTEGRATED PRESSURE SENSOR 0 to 250 kPa (0 to 36.3 psi) 0.2 to 4.91 Volts Output BASIC CHIP CARRIER ELEMENT CASE 867–08, STYLE 1 X–ducer SENSING ELEMENT THIN FILM TEMPERATURE COMPENSATION AND GAIN STAGE #1 2 GND GAIN STAGE #2 AND GROUND REFERENCE SHIFT CIRCUITRY 1 Vout PORT OPTION CASE 867B–04, STYLE 1 PIN NUMBER PINS 4, 5 AND 6 ARE NO CONNECTS 1 2 3 Vout Gnd VS 4 5 6 N/C N/C N/C Figure 1.
