AD1856

TERMINOLOGY

Total Harmonic Distortion

The theoretical dynamic range of an n-bit converter is approx-

imately (6 × n) dB. In the case of the 16-bit AD1856, that is

96 dB. The actual dynamic range of a converter is less than the

theoretical value due to limitations imposed by noise, quantiza-

tion error, and other errors.

Total harmonic distortion (THD) is defined as the ratio of the

square root of the sum of the squares of the harmonic values to

the value of the fundamental input frequency. THD is expressed

in percent (%) or decibels (dB).

THD is a measure of the magnitude and distribution of linearity

error and differential linearity error. The distribution of these

errors may be different, depending on the amplitude of the output

signal. Therefore, to be most useful, THD should be specified for

both large and small signal amplitudes.

Bipolar Zero Error

Bipolar zero error is the deviation in the actual analog output

from the ideal output (0 V) when the twos complement input

code representing half scale (all 0s) is loaded into the input

Settling Time

Differential Linearity Error

Settling time is the time required for the output to reach and

remain within a specified error band about its final value, mea-

sured from the digital input transition. Settling time is the primary

measure of dynamic performance.

Differential linearity error is the measure of the variation in

analog value, normalized to full scale, associated with a 1 LSB

change in the digital input. Monotonic behavior requires that

the differential linearity error not exceed 1 LSB in the negative

direction.

Dynamic Range

The dynamic range specification indicates the ratio of the small-

est signal that the converter can resolve to the largest signal it is

able to produce. As a ratio, it is usually expressed in decibels (dB).

Monotonicity

A digital-to-analog converter is monotonic if the output either

increases or remains constant as the digital input increases.
