EVBA VS1005.A

TECHNICAL NOTE VS1000: Evaluation Kit EVBA 2.0 EVBA 2.0 is a plug and play Evaluation Kit for Colibrys VS1000 accelerometers line. To facilitate the integration in user environment and easily verify the excellent performances of VS1000 sensors, EVBA 2.0 integrates a VS1000 sensor with the user specified range, an ultra-low-noise, high-accuracy 3.3V voltage reference, the decoupling capacitors and output buffers. Features: - Low noise power supply management converting +5V to 3.3V - Output signal conditioning: buffers to enable the use of long lines between the sensor and the user electronic low-pass filters with a cutting frequency - Easy integration into system: 4 fixing holes - Industrial interface Contents 1 EVBA 2.0 description: ......................................................................................................................................... 2 2 Evaluation board function .................................................................................................................................... 4 3 Operation ............................................................................................................................................................. 7 4 Ordering Information ............................................................................................................................................ 9 5 Disclaimer ............................................................................................................................................................ 9 VS1000: Evaluation Kit EVBA 2.0 Document number 30N.EVBA 2.0.A Document revision V1.0 Date of revision 06 September 2016 Note Colibrys reserves the right to change these data without notice Colibrys reserves the right to change these data without notice TECHNICAL NOTE 1 EVBA 2.0 description: 1.1 General overview The EVBA 2.0 is a Kit containing 3 components: - 1 analog evaluation board with soldered VS1000 of corresponding G range. Evaluation board contains electronic circuits to achieve a preliminary signal conditioning - 1 * header connector J1 with 14 pins (to be soldered onto the EVBA dedicated pads) - 1 * mating connector (14 pins) including 13 cm length signal cable ribbon The EVBA 2.0 is protected from outside atmospheric condition effects (temperature, humidity) by a vacuum sealed electrostatic conductive plastic bag Connecting holes J1 Accelerometer VS1000 Decoupling capacitors 3.4mm fixing hole Proximity electronics, with power supply and buffers Note: MEMS accelerometer and electronic circuits on the EVBA can be damaged by electrostatic discharge (ESD). Handle with appropriate precautions and placement should be done in accordance with strict ESD control Please check the integrity of the plastic bag and report if any damage or if the bag is open on arrival. 1.2 Interface Pinout The Table 1 below describes the pin name and interface for the connecting pads J1: Pin Nr Pin name Connector Description J1 1 VTemp f Temperature sensor analog output (buffered) 2 VDD s J1 +3.3 VDC reference voltage sense output (not buffered) 3 OUTN f J1 Negative differential output (buffered) (1) 4 VMID J1 Internal ASIC reference voltage.
