Demonstrating the MAS6116 Stereo Digital Volume Control IC

Helsinki, Finland – 02 April 2012

Micro Analog Systems Oy today announced the new MAS6116 evaluation board, EB6116AA1.

MAS6116 is a stereo volume control IC for high-end audio systems. The capability to work with signal levels up to +/-18V and the extremely low THD, 0.0002% in balanced configuration, makes it very useful in high performance audio systems where the volume is controlled in the analog domain for best performance.

With the MAS6116 evaluation board it’s possible to evaluate the MAS6116 digital potentiometer with either balanced mono or single ended stereo signals. It has the facilities to be controlled either via USB by a program under Linux, Windows or OS X, or via controls on the board itself.

Time Signal Receiver Module

By | News

Helsinki, Finland – 13 January 2012

Micro Analog Systems Oy today announced the availability of the EB6180B1COB module for Time Code Reception (RCC).

The new tiny time signal receiver module comprises of a ferrite antenna and a small PCB that includes a MAS6180B1 AM receiver IC accompanied with necessary filter crystal and capacitor components.MAS6180COB

The MAS6180B1 AM receiver IC converts the time code signal into series of digital pulses which can be directly processed by an appropriate digital circuitry such as micro controller unit (MCU). From the signal both time, date and daylight saving information can be retrieved. The use of a ready made module gives our customers a cost effective solution with an optimized RF design. The included tuned ferrite antenna increases the value of this module even further.

Different versions are available for the 77.5 kHz German DCF77 time signal and the 60 kHz US WWVB, British MSF and Japanese JJY60.

MAS6011 – Solar Cell Energy Harvesting System Manager

By | News

Targeted for solar powered wireless modules

Helsinki, Finland – 02 November 2011 

Micro Analog Systems Oy today announced the MAS6011 Solar Cell Energy Harvesting System Manager.

MAS6011 monitors the supply voltage and charging of a battery-powered system containing a small solar cell. The current consumption of this IC is extremely low, 110 nA, which means the system can charge from very low light conditions and also stay in MAS6011 press photopower down mode for years and still operate directly from the battery before recharging.

To be able to charge a battery also in conditions with very limited light, a large solar cell is usually used. This can on the other hand easily destroy the battery due to over voltage during strong sun light. MAS6011 solves this dilemma and will give secure protection of a secondary 3V battery over a big range of light strengths (lx).

The switching levels have been designed for usage with rechargeable 3V Lithium Vanadium (VL-type) batteries. Those batteries are compact, button-shaped, secondary batteries with very high energy compared to more traditional batteries. The self discharge rate is less than 2% a year which makes them very useful as a power source in systems that might be stored for a long time without re-charging.

Possible applications for MAS6011 include Wireless Sensor Modules, GPS Modules, Electronic locks, Watches, Energy Harvesting etc.

MAS6502 – Piezoresistive Sensor Signal Interface IC

By | News

06.10.2011

Micro Analog Systems Oy introduces MAS6502, a 16-bit Piezoresistive Sensor Signal Interface IC primarily intended for MEMS based pressure sensor modules.

The device uses a ratiometric AD-converter principle employing a delta-sigma conversion technique, giving very good noise performance. Its current consumption is extremely low (2.3 µA) and it can operate at low supply voltage from 2.0 V to 3.6 V which makes it an ideal solution for interfacing a piezo-resistive sensor in power consumption critical portable applications. The effective number of bits (ENOB) of the ADC is 14-bits. The over sampling ratio (OSR) of the Delta-Sigma converter has four values to choose from for further optimization between conversion accuracy, speed and current consumption. The external sensor bridge can be used to sense not only pressure but also temperature, using the built-in sensor sampling switches. The MAS6502 communicates via a standard 2-wire I2C serial bus interface.
