The Motorola MPXS4100A series Barometric Absolute Pressure (BAP) sensor for engine control is designed to sense absolute air pressure.
Motorola’s BAP sensor integrates on–chip, bipolar op amp circuitry and thin film resistor networks to provide a high output signal and temperature compensation.
The small form factor and high reliability of on–chip integration make the Motorola BAP sensor a logical and economical choice for the automotive system designer.
