ZMD21013 Multi-Sensor Interface Circuit Puts Precision, Low Power Consumption at Top of Product's Sophisticated Architecture


ZMD AG - Sensors Expo Rosemont, IL, USA, 9-11 June 2008 - has demonstrated analog-to-digital converters and signal conditioning devices at the Sensors Expo 2008. The Multi-Sensor Interface Circuit  (MUSic) series offer multi-channel and multi-use sensor interfaces for microcontroller-based systems. Known for very high precision and ultra low power, these ICs are ideal for wearable medical instruments; sports and activity monitors that incorporate altimeters, barometers, navigation, and other tools; and industrial systems executing multiple sensor-based measurements such as flowmonitors or scales.


The first device in the MUSic family, the ZMD21013, is a highly integrated smart-power architecture that offers programmable interfaces for up to three resistive bridge sensors. Through its high integration and its ultra-low-power standby-mode, the IC can reduce the average overall bill of materials as well as the overall power consumption of any multisensor-based system. The ZMD21013 connects through a SPI interface to a microcontroller or a digital signal processor (DSP).


The ZMD21013 application-specific standard product (ASSP) contains an on-chip clock generator and a 16x8bit EEPROM to store non-volatile configuration data, calibration coefficients, and an optional user-programmable identification. An SPI-compatible serial interface connects the ZMD21013 to the customerís specific external microcontroller or digital signal processor. The ZMD21013 can be ordered for consumer (0 degrees C to +70 degrees C) as well as for industrial temperature ranges (-25 degrees C to +85 degrees C).


Suited for a variety of markets and applications, the ZMD21013 is an essential enabler for a myriad of consumer, medical and industrial products requiring multiple sensors. Sample devices benefiting from the MUSic family include wearable monitors for assessing blood pressure, glucose, heart rate levels; consumer devices utilizing altimeters, barometers and navigation functions; and industrial instruments like scales and flow and pressure monitors. Other ideal applications include products where highest precision and lowest power consumption are essential qualities.
