ROHM develops the high-speed types and low power consumption type CMOS operation amplifiers and comparators of the high reliability

ROHM Corporation, to striving to make portable digital products such as electricity-saving notebook computer, digital camera, game machine,etc., introduce high reliability CMOS operation amplifier, comparator. Release 24 kinds of 1ch, 2ch at a high speed type together, low power consumption type CMOS operation amplifier, comparator. Begin from the sample outloading, batch productino of 1ch products with big demand at first. Begin to introduce ' BU7261G ', ' BU7261SG ' and low power consumption type ' BU7241G ', ' BU7241SG ' operation amplifier sample at a high speed type in March, and will begin batch productino in June of 2007.

But CMOS comparator has put out ' BU7251G ', ' BU7251SG ' at a high speed type since April of 2007, with low power consumption type ' BU7231G ', ' BU7231SG ' sample, July of 2007 begin batch productino. Integration CMOS operation amplifier and comparator at present, monthly output is up to 10 million, put all 24 kinds of products into batch productino before March of 2008, and then drive on to the goal of the monthly output 30 million boldly. Production is by the previous project ROHM APOLLO DEVICE CO., LTD. (Fukuoka county) ,And then project ROHM INTEGRATED SYSTEMS (THAILAND) CO., LTD. Execution.

In recent years, carry the electronic device of CPU, DSP,etc., with the technical progress of the procedure craft, developing towards direction of micromation fast. Meanwhile, the voltage towards 5V to 3.3V, and then develop to the low-voltage direction of 1.8V. And CMOS operation amplifier developed this time, serial products of comparator, can let CPU, DSP work under the environment of low-voltage of 1.8V. In addition, Input/Output adopts maximum to swing the type, even if can control all signals from GND to the mains voltage freely under the low-voltage. Low power consumption type CMOS operation amplifier ' BU7241G ', consuming current of ' BU7241SG ' are only 70μ A, the consuming current of low power consumption type COMS comparator is only 5μ A, thus has realized the under-current power consumption. It is the ideal choice with the battery-opwered walkie digital products that this kind of energy-conservation is designed.

Have high conversion rate of 1.1V / μ s because of CMOS operation amplifier ' BU7261G ', ' BU7261SG ' at a high speed, and CMOS comparator ' BU7251G ', response time of ' BU7251SG ' are only 0.55μ s, so can play a great role in audio frequency SIGPROC signal processing and various sensory SIGPROC signal processing of the portable digital products.

CMOS operation amplifier that ROHM develops this time, comparator series, adopt its topology of unique circuit, need, improve, input bias current, can realize higher than past the intersection of product and 2 times of 4kV high ESD tolerance. In this way, when assembling, reduce the destruction to IC of static greatly, thus has improved the safe reliability of the products notably. And CMOS operation amplifier ' BU7241SG ', ' BU7261SG ', and CMOS comparator ' BU7231SG ', ' BU7251SG ', it can guarantee until - normal operation in the temperature ranges wides of 40 ℃ to 105 ℃, suitable for to the authenticity requirement than the high products.

Fly and think of Karl and release high-performance MCU 9S08DZ128, expand 8 bit spaces for the car designer

Fly and think of Karl's highly Integrated 9S08DZ128 MCU built-in control device domain network (CAN) Interface, electronic EPROM programmable read-only memory (EEPROM) And the emulation / debugging tool on slice. Imbedding the formula CAN interface offers the connective solution of the ideal for the fact that numerous car and industrial control are employed. But embedded and are erased, has improved systematic design flexibility for EEPROM data load through realizing easily, have dispelled external serial EEPROM. There is integrated developing instrument debugging the function on one that makes the designer carry on the debugging real-timely and fast, speed that thus accelerated the products and appeared on the market. Each above-mentioned integrated function can be used in - the whole car operating temperature range in 40 ℃ to 125 ℃ normally.

On the automobile market, 9S08DZ128 MCU directs against car body, chassis, security and power drive system control. Master industrial control employs and includes the factory, building automation, security system, medical treatment and health care apparatus, Aero-Space electron.

Realize power efficiency through designing

9S08DZ128 utilizes flying to think treatment technology of 0.25 microns of Karl's is made, can expand to the highest 40MHz, aim at offering high performance in the low power is capsulated. Through keeping low power consumption, 9S08DZ128 MCU can let the design engineer of the car continue increasing the electronic content of the car in the Off-The-Shelf 12V battery capacity. Such low-powered function makes this device very suitable for the responsive car application of the power, if ceiling and seat are controlled, controls and the chassis system.

Maxim puts out the undervoltage comparator of ultra low power consumption

Maxim puts out ultra low power consumption, undervoltage comparator: MAX9060– MAX9065. The device offers 2 kinds of capsulation types: 1mm x 1mm UCSP&trade of minification; 5 the intersection of pin and SOT23, the intersection of earth and saving in space very much, simplify prototype machine, design, strengthen design flexibility. MAX9060– MAX9065 work especially suitable for the low battery voltage situation in the porable equipment from 0.9V to 5.5V wide power voltage range.
