Specification Definitions

APERTURE (SAMPLING) DELAY is that time required after

the rise of the clock input for the sampling switch to open.

The Sample/Hold circuit effectively stops capturing the input

signal and goes into the “hold” mode t

AD after the clock goes

high.

APERTURE JITTER is the variation in aperture delay from

sample to sample. Aperture jitter shows up as input noise.

CLOCK DUTY CYCLE is the ratio of the time that the clock

wave form is at a logic high to the total time of one clock

period.

DIFFERENTIAL NON-LINEARITY (DNL) is the measure of

the maximum deviation from the ideal step size of 1 LSB.

Measured at 60 MSPS with a ramp input.

EFFECTIVE NUMBER OF BITS (ENOB, or EFFECTIVE

BITS) is another method of specifying Signal-to-Noise and

Distortion Ratio, or SINAD. ENOB is defined as (SINAD –

1.76) / 6.02 and says that the converter is equivalent to a

perfect ADC of this (ENOB) number of bits.

FULL POWER BANDWIDTH is a measure of the frequency

at which the reconstructed output fundamental drops 3 dB

below its low frequency value for a full scale input.

FULL-SCALE ERROR is a measure of how far the last code

transition is from the ideal 11⁄2 LSB below V

RT and is defined

as:

V

max + 1.5 LSB – VRT

where V

max is the voltage at which the transition to the

maximum (full scale) code occurs.

INTEGRAL NON-LINEARITY (INL) is a measure of the

deviation of each individual code from a line drawn from zero

scale (1⁄2 LSB below the first code transition) through positive

full scale (1⁄2 LSB above the last code transition). The devia-

tion of any given code from this straight line is measured

from the center of that code value. The end point test method

is used. Measured at 60 MSPS with a ramp input.

INTERMODULATION DISTORTION (IMD) is the creation of

additional spectral components as a result of two sinusoidal

frequencies being applied to the ADC input at the same time.

it is defined as the ratio of the power in the second and thrid

order intermodulation products to the power in one of the

original frequencies. IMD is usually expressed in dBFS.

LSB (LEAST SIGNIFICANT BIT) is the bit that has the

smallest value or weight of all bits. This value is

(V

RT −VRB)/2

n

where “n” is the ADC resolution, which is 8 in the case of the

ADC08L060.

MISSING CODES are those output codes that are skipped

and will never appear at the ADC outputs. These codes

cannot be reached with any input value.

MSB (MOST SIGNIFICANT BIT) is the bit that has the

largest value or weight. Its value is one half of full scale.

OUTPUT DELAY is the time delay after the rising edge of

the input clock before the data update is present at the

output pins.

OUTPUT HOLD TIME is the length of time that the output

data is valid after the rise of the input clock.

PIPELINE DELAY (LATENCY) is the number of clock cycles

between initiation of conversion and when that data is pre-

sented to the output driver stage. New data is available at

every clock cycle, but the data lags the conversion by the

Pipeline Delay plus the Output Delay.

POWER SUPPLY REJECTION RATIO (PSRR) is a mea-

sure of how well the ADC rejects a change in the power

supply voltage. For the ADC08L060, PSRR1 is the ratio of

the change in Full-Scale Error that results from a change in

the dc power supply voltage, expressed in dB. PSRR2 is a

measure of how well an a.c. signal riding upon the power

supply is rejected and is here defined as

where SNR0 is the SNR measured with no noise or signal on

the supply lines and SNR1 is the SNR measured with a

1 MHz, 200 mV

P-P signal riding upon the supply lines.

SIGNAL TO NOISE RATIO (SNR) is the ratio, expressed in

dB, of the rms value of the input signal at the output to the

rms value of the sum of all other spectral components below

one-half the sampling frequency, not including harmonics or

dc.

SIGNAL TO NOISE PLUS DISTORTION (S/(N+D) or

SINAD) is the ratio, expressed in dB, of the rms value of the

input signal at the output to the rms value of all of the other

spectral components below half the clock frequency, includ-

ing harmonics but excluding dc.

SPURIOUS FREE DYNAMIC RANGE (SFDR) is the differ-

ence, expressed in dB, between the rms values of the input

signal at the output and the peak spurious signal, where a

spurious signal is any signal present in the output spectrum

that is not present at the input.

TOTAL HARMONIC DISTORTION (THD) is the ratio ex-

pressed in dB, of the rms total of the first nine harmonic

levels at the output to the level of the fundamental at the

output. THD is calculated as

where f

1 is the RMS power of the fundamental (output)

frequency and f

2 through f10 are the RMS power of the first

9 harmonic frequencies in the output spectrum.

ZERO SCALE OFFSET ERROR is the error in the input

voltage required to cause the first code transition. It is de-

fined as

V

OFF =VZT −VRB

where V

ZT is the first code transition input voltage.

2nd HARMONIC DISTORTION (2nd HARM) is the differ-

ence, expressed in dB, between the rms power in the output

fundamental frequency and the power in its 2nd harmonic at

the output.

3rd HARMONIC DISTORTION (3rd HARM) is the differ-

ence, expressed in dB, between the rms power in the output

fundamental frequency and the power in its 3rd harmonic at

the output.
