GENERAL DESCRIPTION
The SPT7810 A/D converter is a 10-bit monolithic converter
capable of word rates of a minimum of 20 MSPS. On board
track/hold function assures excellent dynamic performance
without the need for external components. Drive require-
ment problems are minimized with an input capacitance of
only 5 pF.
Inputs and outputs are ECL to provide a higher level of noise
immunity in high speed system applications. An overrange
output signal is provided to indicate overflow conditions.
Output data format is straight binary. Power dissipation is
very low at only 1.3 watts with power supply voltages of +5.0
and -5.2 volts. The SPT7810 also provides a wide input
voltage swing of ±2.0 volts.
The SPT7810 is available in a 28-lead ceramic sidebrazed
DIP, PDIP, and die form. Commercial and industrial tempera-
ture ranges are currently offered. Contact the factory for
availability of military temperature range and /883 processed
units.

SPECIFICATION DEFINITIONS
APERTURE DELAY
Aperture delay represents the point in time, relative to the
rising edge of the CLOCK input, that the analog input is
sampled.
APERTURE JITTER
The variations in aperture delay for successive samples.
DIFFERENTIAL GAIN (DG)
A signal consisting of a sine wave superimposed on various
DC levels is applied to the input. Differential gain is the
maximum variation in the sampled sine wave amplitudes at
these DC levels.
DIFFERENTIAL NONLINEARITY (DNL)
Error in the width of each code from its theoretical value.
(Theoretical = VFS/2N)
INTEGRAL NONLINEARITY (INL)
Linearity error refers to the deviation of each individual code
(normalized) from a straight line drawn from -Fs through +Fs.
The deviation is measured from the edge of each particular
code to the true straight line.
OUTPUT DELAY
Time between the clock's triggering edge and output data
valid.
DIFFERENTIAL PHASE (DP)
A signal consisting of a sine wave superimposed on various
DC levels that is applied to the input. Differential phase is the
variation in the sampled sine wave phases at these DC levels.
OVERVOLTAGE RECOVERY TIME
The time required for the ADC to recover to full accuracy after
an analog input signal 125% of full scale is reduced to 50%
of the full-scale value.
EFFECTIVE NUMBER OF BITS (ENOB)
SINAD = 6.02N + 1.76, where N is equal to the effective
number of bits.

1.76
± FULL-SCALE ERROR (GAIN ERROR)
Difference between measured full scale response
[(+Fs) - (-Fs)] and the theoretical response (+4 V -2 LSBs)
where the +FS (full scale) input voltage is defined as the
output transition between 1-10 and 1-11 and the -FS input
voltage is defined as the output transition between 0-00 and
0-01.
INPUT BANDWIDTH
Small signal (50 mV) bandwidth (3 dB) of analog input stage.
SIGNAL-TO-NOISE RATIO (SNR)
The ratio of the fundamental sinusoid power to the total noise
power. Harmonics are excluded.
SIGNAL-TO-NOISE AND DISTORTION (SINAD)
The ratio of the fundamental sinusoid power to the total noise
and distortion power.
TOTAL HARMONIC DISTORTION (THD)
The ratio of the total power of the first 64 harmonics to the
power of the measured sinusoidal signal.
SPURIOUS FREE DYNAMIC RANGE (SFDR)
The ratio of the fundamental sinusoidal amplitude to the
single largest harmonic or spurious signal.
