Low jitter, fast, stable chopper circuit

Worcester, Massachusetts- 亚博棋牌游戏Allegro MicroSystems announced a new dual channel lateral of hall effect sensor IC, it can provide instruction target rotation speed and direction of a variety of digital output signal.Hall element adopt optical lithography, the calibration precision is more than 1 microns.Maintain accurate mechanical position between the two activities hall element can eliminate small mouth's main manufacturing difficulties of direction finding applications.A1233Is a high sensitive and temperature stability of magnetic sensing device, is under the harsh automotive and industrial environment for sensing ring magnet system is ideal for speed and direction.

Allegro 'A1233 monolithic integrated circuit (IC) contains two independent hall effect double pole switch, switch between the two are separated by 1.63 mm, which can provide excellent speed for small target geometry size and direction information.Very low drift amplifiers can ensure the switch, the symmetry between the orthogonal to maintain the signal.Allegro ® stability chopper technology patents can eliminate the deviation of each channel, within the specified operating temperature and voltage stability operation.

In addition, the high frequency chopper circuit can also be within the IC digital comparator input conditions to achieve higher analog signal to noise ratio.So A1233 can achieve industry-leading digital output jitter performance, this is crucial for high performance motor commutation applications.Chip low dropout linear (they) voltage regulator allows the device used in a wide working voltage range.After assembly factory programming to ensure relatively said sensitive switch point between the two switches.

SOIC A1233 plastic 8 pin surface installation package (L) and SIP (K) plastic 4 pin.Both kinds of packaging can be used for - 40 ° C to 150 ° C temperature range.Each is lead-free packaging, fog pin box with 100% of tin plating.
