Readjustable resistors compensate and
calibrate
Low-power low-TC readjustable resistors are designed to compensate and calibrate precision analogue circuits.
Microbridge Technologies has a new family of low-power low-TC readjustable resistors designed to compensate and calibrate precision analogue circuits Microbridge has previously shown its capability to calibrate individual electronic devices such as voltage references, sensors or circuits needing adjustments with passive, electrically adjustable resistors

The MBSTC-02 incorporates low-noise operational amplifiers with Rejustors to provide precise signal conditioning with integrated temperature correction.
The new Rejustors can be used with off-the-shelf National Instruments hardware (NI-cDAQ 9172) to calibrate a wide range of circuits in parallel.
"There are numerous solutions on the market to improve accuracy and precision of analogue circuits", says Bob Frostholm, Vice President, Marketing and Strategic Alliances at Microbridge.
"Each existing solution has some set of drawbacks that Rejustors can alleviate such as limited temperature range, limited maximum frequency of operation, requiring power, requiring a laser, and more".

"Rejustors offer high temperature operation to 125C or higher, high frequency operation in excess of 2GHz, requires no power to operate in circuit, has no wiper resistance, and is adjustable to precision levels 0.1% or better".
Microbridge Rejustors have a wide variety of applications.
They are suitable for precision analogue compensation in military, aerospace and satellite applications.
Automotive applications range from optical systems to engine sensors and tire-pressure monitor.
As a sealed device, the Rejustor is well suited for operation in harsh and demanding environments.
Industrial applications range from simple calibration of power supplies to calibration of sensors of many kinds including phototransistors, pressure sensors and magnetic proximity sensors.
Consumer applications include LCD screen adjustments and timing devices.
In medical and science, Microbridge calibration techniques are ideal for use in catheter applications.
In semiconductors, Microbridge's CMOS based technology enables integration of Rejustor calibration and compensation devices for designs that require better precision than fuses, digital potentiometers or laser trimming can achieve.
The new devices are available off the shelf through Microbridge's worldwide distributor, Future Electronics.
All members of the low power family are priced at US $0.99 at 1000 piece quantities.
Each QFN package contains two Rejustor elements (R1, R2) making it easier to implement divider networks where the TC of the two resistors must be equally matched. Request a free brochure from Microbridge ...
