Analogue compensation in one
Low-power low-TC re-adjustable resistors meet customer needs for a low-cost single-element device to compensate and calibrate precision analogue circuits.
Microbridge Technologies has a new family of low-power low-TC re-adjustable resistors designed to meet customer needs for a low-cost single-element device 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

Readjustable resistors compensate and calibrate
Low-power low-TC readjustable resistors are designed to compensate and calibrate precision analogue circuits.
Resistors compensate for temperature drift
Having two rejustor elements in the same package makes it easier to implement divider networks where resistors must be equally matched.
The new single, low power Rejustor will emphasise how to calibrate devices and circuits for mass production.
It can be used with off-the-shelf hardware from National Instruments (NI-cDAQ 9172) to calibrate a wide range of circuits in parallel.
"This release addresses additional market segments where only one variable resistor is required", says Bob Frostholm, Vice President, Marketing and Strategic Alliances at Microbridge.

The MBSTC-02 incorporates low-noise operational amplifiers with Rejustors to provide precise signal conditioning with integrated temperature correction.
"These new parts maintain the same electrical specifications as our dual devices and allow us to hit new price points required by high volume consumer oriented applications such as frequency tuning for many of the popular newly introduced wireless products".
"In addition, our Rejustors offer high temperature operation to 125C or higher, high frequency operation, require no power to operate in circuit, have no wiper resistance, and are adjustable to precision levels of 0.1% or better".
Microbridge single Rejustors have a wide variety of applications.
In addition to consumer and other wireless 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.
Other consumer applications include LCD-screen VCOM 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 $0.65 for 1000-piece quantities. Request a free brochure from Microbridge ...
