Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
DEFINITIONS OF SPECIFICATIONS
Gain Error
The gain of a voltage-to-frequency converter is the scale factor
setting that provides the nominal conversion relationship, e.g.,
1 MHz full scale. The gain error is the difference in slope
between the actual and ideal transfer functions for the V-F
converter.
Linearity Error
The linearity error of a V-F is the deviation of the actual
transfer function from a straight line passing through the
endpoints of the transfer function.
Gain Temperature Coefficient
The gain temperature coefficient is the rate of change in full-
scale frequency as a function of the temperature from +25°C to
TMIN or TMAX.
