NEW PRODUCT ANNOUNCEMENT
NEW SENSOR INTERFACE IC FEATURES WIDE RANGE PROGRAMMABLE GAIN, PROGRAMMABLE FILTERS, 12 BIT A/D CONVERTER AND ON CHIP ANTI ALIASING
SAN JOSE, California, November 1, 2003---Engineers at Mixed Signal Integration have developed a new integrated circuit called the MSSPSI that will interface voltage output sensors to a microprocessor. The Smart Programmable Sensor Interface chip takes small analog signals from a sensor or MEMs device and anti-aliases, filters and amplifies them. Then the signals are converted into a digital signal output. These functions are controlled by an external uP through the MSSPI's on-chip serial interface.
The Smart Programmable Sensor Interface chip can be used for MEMS interface and sensors for pressure, vibration, temperature and accelerometers, among others. Medical applications such as bio-sensors are another use for the MSSPSI.
The MSSPSI has a low noise preamp that can be configured for differential or single-ended mode. The chip also contains a digital serial input port, 12 bit A to D converter, temperature sensor, DC offset adjustment circuit, a 4 input multiplexor for the A to D, and anti-aliasing. The on chip bias section can be selected for different power modes through the serial port. The MSSPSI takes a single supply from 3.3 V to 5.5 V DC. Typical operating current in low power mode is only 2 mA.
The MSSPSI is packaged in a 32 pin plastic LQFP. Operating temperature is –40 to +85 degrees C. In 10,000 piece quantities, the MSSPSI costs $5.95 each.
