"# !# the motorola MPX4101A/mpxa4101ac series manifold absolute pressure (map) sensor for engine control is designed to sense absolute air pressure within the intake manifold. this measurement can be used to compute the amount of fuel required for each cylinder. the small form factor and high reliability of onchip integration makes the motorola map sensor a logical and economical choice for automotive system designers. the MPX4101A/mpxa4101ac series piezoresistive transducer is a stateoftheart, monolithic, signal conditioned, silicon pressure sensor. this sensor combines advanced micromachining tec hniques, thin film metallization, and bipolar semiconductor processing to provide an accurate, high level analog output signal that is proportional to applied pressure. figure 1 shows a block diagram of the internal circuitry integrated on a pressure sensor chip. features ? 1.72% maximum error over 0 to 85 c ? specifically designed for intake manifold absolute pressure sensing in engine control systems ? temperature compensated over 40 c to +125 c ? durable epoxy unibody element or thermoplastic (pps) surface mount package application examples ? manifold sensing for automotive systems ? ideally suited for microprocessor or microcontrollerbased systems ? also ideal for nonautomotive applications figure 1. fully integrated pressure sensor schematic ( % %!% ! !& ( 7<; ! & ! & #$&'$ " #!%& "! ! ! %& ! %& ! $"'! $$! % & $' &$+ # !% ! $ !"
