MAS6512 – Capacitive Sensor Signal Interface IC

By | News

23.08.2012

Micro Analog Systems Oy introduces MAS6512, a 16 Bit Capacitive 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 (1.9 µA) and it can operate at low supply voltage from 1.8 V to 3.6 V which makes it an ideal solution for interfacing a capacitive sensor in power consumption critical portable applications. The resolutionof the ADC is 14-bits. The over sampling ratio (OSR) of the Delta-Sigma converter has five values to choose from for further optimization between conversion accuracy, speed and current consumption. MAS6512 capacitive sensor interface IC can interface both single and dual capacitance sensors. It has internal temperature sensor for temperature measurement and temperature compensation purposes. The MAS6512 communicates via a standard 2-wire I2C and 4-wire SPI bus interface.

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.
