DEFINITIONS OF SPECIFICATIONS

GAIN ERROR—The gain of a voltage-to-frequency converter is

that scale factor setting that provides the nominal conversion

relationship, e.g., 1 MHz full scale. The “gain error” is the dif-

ference 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 tempera-

ture coefficient is the rate of change in full-scale frequency as a

function of the temperature from +25°C to TMIN or TMAX.
