GENERAL DESCRIPTION

11  
The ADXRS150EB is a simple evaluation board that allows the  
user to quickly evaluate the performance of the ADXRS150ABG  
yaw rate gyro. No additional external components are required  
for operation. The ADXRS150EB has a 20-lead dual-in-line  
(0.3 inch width by 0.1 inch pin spacing) interface that allows  
the user to easily prototype products without having to deal with  
BGA soldering. The 0.4 square inch outline of the ADXRS150EB  
is still among the smallest gyros available today.

CIRCUIT DESCRIPTION  
CMID  
The schematic of the ADXRS150EB is shown in Figure 1.  
It is identical to the suggested application shown in the  
ADXRS150ABG data sheet.

The analog and power grounds (AGND and PGND) have  
separate ground planes and are joined at one point. The user  
may cut this trace if separate ground schemes are desired.

PIN 20  
Note that the analog supply voltage and charge pump supply volt-  
age (AVCC and PDD) are not connected on the ADXRS150EB  
and that users must connect these as appropriate to their  
application.

The parts layout of the ADXRS150EB is shown in Figure 2,  
and the parts list for the ADXRS150EB is shown in Table I.  
As delivered, the ADXRS150EB is set for 40 Hz bandwidth  
(COUT = 22 nF). The user may add an external capacitor to  
further reduce the bandwidth and improve the noise floor.

SPECIAL NOTES ON HANDLING  
Figure 2. ADXRS150EB Parts Layout  
Note that the ADXRS150EB is not reverse polarity protected.  
Reversing the power supply or applying inappropriate voltages  
to any pin (outside the data sheets Absolute Maximum Ratings)  
may damage the ADXRS150EB.
