GENERAL DESCRIPTION
The ISZ-1215EVB provides a simple means of evaluating the ISZ-
1215 Z-axis angular rate gyroscope. The gyro contains all
required conditioning electronics in a single chip measuring 4 x 5
x 1.2mm. The ISZ-1215 incorporates a Z-axis low-pass filter and
an EEPROM for on-chip factory calibration of the sensor. Factory
trimmed gyro scale factor eliminates the need for external active
components and end-user calibration. A built-in Proportional-To-
Absolute-Temperature (PTAT) sensor provides temperature
compensation information. The product is lead-free and Green
Compliant.

Special Instructions
Electrostatic Discharge Sensitivity
The ISZ-1215 gyro can be permanently damaged by an electrostatic discharge. ESD precautions for
handling and storage are recommended.
Jumper Connector
The ISZ-1215 evaluation board is equipped with a jumper connector to control the voltage supplied to
the gyro. When the jumper is located in the “up” or standard position as shown in the picture above, the
5 Volts being supplied to the gyro is regulated to 3 Volts using an on-board regulator. When the jumper
is located in the “down” position, the on-board regulator is bypassed and the gyro is being directly
supplied with the voltage on Pins 9 and 19 of the IC.
