A MICROPOWER PRECISION DIFFERENCE AMPLIFIER WITH A VERY HIGH COMMON MODE INPUT VOLTAGE RANGE.THE AMPLIFIER IS IN THE FORM OF A MONOLITHIC INTEGRATED CIRCUIT 8-PIN SO PACKAGE. IT HAS PIN SELECTABLE GAINS OF 1 OR 10. THE AMPLIFIER OPERATES OVER A ±250V COMMON MODE VOLTAGE RANGE ON A ±15V SUPPLY. THE INPUTS ARE FAULT PROTECTED FROM COMMON MODE VOLTAGE TRANSIENTS UP TO ±350V AND DIFFERENTIAL VOLTAGES UP TO ±500V. IT IS IDEALLY SUITED FOR BOTH HIGH SIDE AND LOW SIDE CURRENT OR VOLTAGE MONITORING. ON A SINGLE 5V SUPPLY AND HAS AN ADJUSTABLE 85V INPUT RANGE, 70DB MIN CMRR AND DRAWS LESS THAN 120µA SUPPLY CURRENT. THE RAIL-TO-RAIL OUTPUT MAXIMIZES THE DYNAMIC RANGE, ESPECIALLY IMPORTANT FOR SINGLE SUPPLIES AS LOW AS 2.7V. APPLICATIONS INCLUDE: BATTERY CELL VOLTAGE MONITORING, HIGH VOLTAGE CURRENT SENSING, SIGNAL ACQUISITION IN NOISY ENVIRONMENTS, INPUT PORTECTION, LEVEL SENSING AND ISOLATION.

THE PRODUCT IS AN INTEGRATED CIRCUIT CHIP CONTAINING A MICROPROCESSOR (SPARC) AND ASSOCIATED FUNCTIONS NETWORK, MEMORY CONTROLLER, CACHE, ..ETC. THIS CHIP IS HIGH-RELIABILTIY AND DESIGNED TO WORK IN HARSH ENVIRONMENTS SUCH AS AEROSPACE AND SPACE.

INTEGRATED CIRCUIT WHICH ENABLES/CONTROLS COMMUNICATION BETWEEN THE USB AND THE VARIOUS DEVICES. THIS IC IS A COMPONENT ON A PCB UNIT. THE UNIT IS USED FOR TESTING PORTABLE ELECTRICAL APPLIANCES.

A MAGNETICALLY BIASED HALL-EFFECT INTEGRATED CIRCUIT, THAT INCLUDES A MAGNET, BIPOLAR TRANSISTORS, CMOS DEVICES, POLYSILICON RESISTORS, CAPACITORS AND SPECIALLY-DESIGNED EPITAXIAL SILICON CONFIGURED AS A HALL ELEMENT WITHIN THE SINGLE SILICON SUBSTRATE. THE INTEGRATED CIRCUIT IS ONE COMPONENT OF A FINISHED SENSOR ASSEMBLY. TYPICALLY IT IS ATTACHED TO A PRINTED CIRCUIT BOARD, WITH EITHER ELECTRICAL CONNECTORS OR WIRING HARNESS THEN ATTACHED. IT CANNOT BE DIRECTLY INCORPORATED INTO AUTOMOBILE OR OTHER APPLICATIONS, WITHOUT FURTHER PROCESSING. OTHER COMPONENTS SUCH AS RESISTORS, CAPACITORS AND MICROPROCESSORS ARE ALSO ADDED AND THEN THE WHOLE ASSEMBLY WOULD ALSO NEED TO BE OVERMOULDED; TO MAKE IT INTO A FINISHED SENSOR.

HYBRID MICROCIRCUITS CONSISTING A MAGNETICALLY BIASED HALL-EFFECT INTEGRATED CIRCUIT, DISCRETE RESISTORS AND CAPACITORS ON A PRINTED CIRCUIT BOARD ENCAPSULATED IN CASING. THE HALL EFFECT IC INCLUDES A MAGNET, BIPOLAR TRANSISTORS, CMOS DEVICES, POLYSILICON RESISTORS, CAPACITORS AND SPECIALLY-DESIGNED EPITAXIAL SILICON CONFIGURED AS A HALL ELEMENT WITHIN THE SINGLE SILICON SUBSTRATE. THE HYBRID MICROCIRCUIT IS ONE COMPONENT OF A FINISHED SENSOR ASSEMBLY. TYPICALLY IT IS ATTACHED TO A PRINTED CIRCUIT BOARD, WITH EITHER ELECTRICAL CONNECTORS OR WIRING HARNESS THEN ATTACHED. IT CANNOT BE DIRECTLY INCORPORATED INTO AUTOMOBILE OR OTHER APPLICATIONS, WITHOUT FURTHER PROCESSING.
