Graz, Austria, February 24, 2010--SensorDynamics, sensor manufacturer for automotive and industrial applications, today launched the SD 41x, a new single-chip solution for AMR-sensors interface. The low-cost AMR sensors are used across  automotive applications; primarily for position and angle measurements.

As the differential output signals of an AMR-sensor are lower than 100 mV, in order to achieve sufficiently high position accuracy, these signals have to be amplified and filtered before being processed in the microcontroller. Additional discrete components required for such amplification have a significant impact on total costs. As SD41x integrates the necessary amplifiers, filters, ADCs and a microcontroller, costs are significantly lowered. The gain, the band width and the resolution of the ADCs are configurable for each application by software, which significantly reduces the usual effort of configuration by external resistors and capacitors. In addition, individual parameters of each sensor module can be easily adjusted and fine tuned at the end of the sensor module manufacturing line. Its ability to configure parameters by software helps shortening the time to market as well. The SD41x comes with a development tool kit that includes an easy to use graphical full-screen configurator, the necessary drivers, the manual and C-code examples.

Further Products Features
The SD41x is the unique single-chip solution which contains two high precision sigma-delta 14-bit ADCs and one 8-bit microcontroller. In addition, the system has fail-safe properties built in which are important for safety critical and safety relevant applications. Also, voltage regulators, several sleep-down modes and data interfaces (SPI, LIN, PW; UART, DAC) are available.

Availability and Price
According to AEC-Q100 approved SD41x with integrated 32kB EEPROM in QFNL64 is available for the price of 7,78 EUR
for 1k. SensorDynamics can offer a competitive price for volume production. Evaluation boards and samples can be ordered online at www.sensordynamics.cc.
