Products Overview
A17700 Pressure Sensor Interface and Signal Conditioning IC
Allegro MicroSystems
Allegro's A17700 pressure sensor interface and signal conditioning IC with polynomial signal compensation and advanced diagnostics
Allegro'sA17700 sensor interface IC device designed to interface a piezoresistive bridge or MEMS solution.
It is suited for high and mid-pressure applications where piezoresistive bridge and resistance on thin film are used for pressure measurements. The A17700 diagnostic functions satisfy automotive safety-critical application specifications. Applications include oil injection in engine and automatic transmissions, EGR, and fuel, air, and coolant pressures.
The Allegro MicroSystems A17700 Pressure Sensor Interface ICs diagnostic functions comply with required automotive safety-critical application specifications. The A17700 is configurable with a Manchester programming interface. The Sensor Interface ICs include on-chip EEPROM technology capable of supporting up to 100read/write cycles for programming of calibration parameters.
The A17700 is housed in a 24-pin 4mm × 4mm QFN package with a wettable flank and exposed thermal pad. The 17700 is ideal for medium and high-pressure automotive applications such as oil injection in the engine and automatic transmission, EGR, fuel pressure, air pressure, coolant pressure.
