DEFINITIONS OF SPECIFICATIONS

BIPOLAR ZERO ERROR: When the AD660 is connected for

bipolar output and 10 . . . 000 is loaded in the DAC, the devia-

tion of the analog output from the ideal midscale value of 0 V is

called the bipolar zero error.

INTEGRAL NONLINEARITY: Analog Devices defines

integral nonlinearity as the maximum deviation of the actual,

adjusted DAC output from the ideal analog output (a straight

line drawn from 0 to FS–1 LSB) for any bit combination. This

is also referred to as relative accuracy.

DRIFT: Drift is the change in a parameter (such as gain, offset

and bipolar zero) over a specified temperature range. The drift

temperature coefficient, specified in ppm/°C, is calculated by

measuring the parameter at T_MIN, 25°C and T_MAXand dividing

the change in the parameter by the corresponding temperature

change.

DIFFERENTIAL NONLINEARITY: Differential nonlinearity

is the measure of the change in the analog output, normalized to

full scale, associated with a 1 LSB change in the digital input

code. Monotonic behavior requires that the differential linearity

error be greater than or equal to –1 LSB over the temperature

range of interest.

TOTAL HARMONIC DISTORTION + NOISE: Total har-

monic distortion + noise (THD+N) is defined as the ratio of the

square root of the sum of the squares of the values of the har-

monics and noise to the value of the fundamental input fre-

quency. It is usually expressed in percent (%).

MONOTONICITY: A DAC is monotonic if the output either

increases or remains constant for increasing digital inputs with

the result that the output will always be a single-valued function

of the input.

THD+N is a measure of the magnitude and distribution of lin-

earity error, differential linearity error, quantization error and

noise. The distribution of these errors may be different, depend-

ing upon the amplitude of the output signal. Therefore, to be

the most useful, THD+N should be specified for both large and

small signal amplitudes.

GAIN ERROR: Gain error is a measure of the output error be-

tween an ideal DAC and the actual device output with all 1s

loaded after offset error has been adjusted out.

OFFSET ERROR: Offset error is a combination of the offset

errors of the voltage-mode DAC and the output amplifier and is

measured with all 0s loaded in the DAC.
