描述: | A1230 Dual Channel Quadrature Hall Effect Bipolar Switch, Allegro MicrosystemsThe Allegro Microsystems A1230 is a dual-channel, bipolar switch with two Hall-effect sensing elements. Each element provides a separate digital output for speed and direction signal processing. The Hall elements are aligned with an accuracy greater than 1 μm. This accuracy makes it ideal for use in ring magnet based, speed and direction systems located in harsh automotive and industrial environments. The A1230 contains two independent Hall-effect bipolar switches located 1 mm apart. The digital outputs are out of phase so the outputs are in quadrature when interfaced with the proper ring magnet design. Low-drift amplifiers guarantee symmetry between the switches. The Allegro high-frequency chopper-stabilisation cancels offsets in each channel providing stable operation over the full specified temperature and voltage ranges. The A1230 is available in a plastic 8-pin SOIC surface mount package and a plastic 4-pin SIP.AEC-Q100 automotive qualified Two matched Hall-effect switches on a single substrate 1 mm Hall element spacing Superior temperature stability and industry-leading jitter performance through use of advanced chopper stabilisation topology Integrated LDO regulator provides 3.3 V operation Integrated ESD protection from outputs and VCC to ground High-sensitivity switchpoints Robust structure for EMC protection Reverse-battery protection on supply and both output pins ### 霍尔效应传感器,Allegro Microsystems |
