INPUT REFERRED NOISE

DEFINITIONS OF SPECIFICATIONS

The rms output noise is measured using histogram techniques.

The ADC output codes’ standard deviation is calculated in

LSB, and converted to an equivalent voltage, using the relation-

ship 1 LSB = 4 V/16384 = 244 mV. The noise is then referred

to the input of the AD9814 by dividing by the PGA gain.

INTEGRAL NONLINEARITY (INL)

Integral nonlinearity error refers to the deviation of each indi-

vidual code from a line drawn from “zero scale” through “posi-

tive full scale.” The point used as “zero scale” occurs 1/2 LSB

before the first code transition. “Positive full scale” is defined as

a level 1 1/2 LSB beyond the last code transition. The deviation

is measured from the middle of each particular code to the true

straight line.

CHANNEL-TO-CHANNEL CROSSTALK

In an ideal three channel system, the signal in one channel will

not influence the signal level of another channel. The channel-

to-channel crosstalk specification is a measure of the change that

occurs in one channel as the other two channels are varied. In

the AD9814, one channel is grounded and the other two chan-

nels are exercised with full-scale input signals. The change in the

output codes from the first channel is measured and compared

with the result when all three channels are grounded. The differ-

ence is the channel-to-channel crosstalk, stated in LSB.

DIFFERENTIAL NONLINEARITY (DNL)

An ideal ADC exhibits code transitions that are exactly 1 LSB

apart. DNL is the deviation from this ideal value. Thus every

code must have a finite width. No missing codes guaranteed to

14-bit resolution indicates that all 16384 codes, respectively,

must be present over all operating ranges.

OFFSET ERROR

APERTURE DELAY

The first ADC code transition should occur at a level 1/2 LSB

above the nominal zero scale voltage. The offset error is the

deviation of the actual first code transition level from the ideal

level.

The aperture delay is the time delay that occurs from when a

sampling edge is applied to the AD9814 until the actual sample

of the input signal is held. Both CDSCLK1 and CDSCLK2

sample the input signal during the transition from high to low,

so the aperture delay is measured from each clock’s falling edge

to the instant the actual internal sample is taken.

GAIN ERROR

The last code transition should occur for an analog value

1 1/2 LSB below the nominal full-scale voltage. Gain error is

the deviation of the actual difference between first and last code

transitions and the ideal difference between the first and last

code transitions.

POWER SUPPLY REJECTION

Power Supply Rejection specifies the maximum full-scale change

that occurs from the initial value when the supplies are varied

over the specified limits.
