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
