Maxim rolls out high-end electric current to detect amplifier
From;    Author:Stand originally

MaximIntegratedProducts rolls out the high-end electric current with the smallest inside dimension of course of study to detect amplifier MAX9938. This parts of an apparatus uses UCSP of 4 solder ball to enclose, dimension is the 1/9 that introduces the competitive product that SOT23 encloses only. Additional, block of cipher telegram of essence of the buy inside parts of an apparatus, leave out exterior gain installs resistor, reduced the integral size of plan greatly thereby. Parts of an apparatus uses technology of company proprietary BiCMOS, can realize the static electric current of the lowest inside course of study and highest precision. MAX9938 design work is in limits of wide input voltage (1.6V comes 28V) , the ideal that is equipment of power supply of batteries of computer of player of camera of intelligent phone, number, PDA, MP3, notebook and other chooses, be opposite in these application the requirement of the index such as electric current of small size, small static state and high accuracy is relatively strict.

The electricity that portable equipment needs small size, high accuracy detects amplifier

Electric current detects amplifier is the important parts of an apparatus in portable equipment. These small size integrated circuit (the charging that IC) uses at measuring batteries normally and discharge electric current, still can monitor a likelihood to need to give out heat through dropping report to control the power source with power comsumption | Manostat input. Accordingly, high to assuring reliability mixes high accuracy prolong battery life crucial.

Carry out a proof, having extremely low input to break precision of harmonic tall gain at the same time is very difficult, and more such in the portable application with exterior at present smaller size. However, MAX9938 is behaved however in these domains particularly outstanding.

The plan of economic space provides superior performance

MAX9938 can provide the smallest plan measure inside course of study. This IC uses fine 1mmx1mmx0.6mm, UCSP of 4 solder ball is enclosed, its dimension is the 1/9 that introduces the competitive product that SOT23 encloses only. In addition, block of cipher telegram of essence of the buy inside parts of an apparatus, leave out what need in competitive product 2 to 3 exterior gain installs resistor. In fact, MAX9938 is very fine, even smaller than singular resistance 12% !
