Ø150Ø/s Single Chip Rate Gyro

Evaluation Board

ADXRS150EB

GENERAL DESCRIPTION

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

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.

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

Note that the ADXRS150EB is not reverse polarity protected.

Reversing the power supply or applying inappropriate voltages

to any pin (outside the data sheetâs Absolute Maximum Ratings)

may damage the ADXRS150EB.
