GENERAL INTRODUCTION
The AD9432 is a 12-bit monolithic sampling analog-to-digital
converter with an on-chip track-and-hold circuit and is optimized
for high-speed conversion and ease of use. The product operates
at a 105 MSPS conversion rate with outstanding dynamic per-
formance over its full operating range.
The ADC requires only a single 5.0 V power supply and a
105MHz encode clock for full-performance operation. No
external reference or driver components are required for many
applications. The digital outputs are TTL/CMOS compatible
and a separate output power supply pin supports interfacing
with 3.3 V logic. The encode input supports either differential
or single-ended and is TTL/CMOS-compatible.
Fabricated on an advanced BiCMOS process, the AD9432 is
available in a 52-lead plastic quad flatpack package (LQFP)
specified over the industrial temperature range (–40°C to
+85°C).
AD9432–SPECIFICATIONS
(VDD = 3.3 V, VCC = 5.0 V; external reference; differential encode input, unless
otherwise noted)
AD9432
NOTESGain error and gain temperature coefficients are based on the ADC only (with a fixed 2.5 V external reference and a 2 V p-p differential analog input).tV and tPD are measured from the transition points of the ENCODE input to the 50%/50% levels of the digital outputs swing. The digital output load during test is
not to exceed an ac load of 10 pF or a dc current of ±40 µA. Rise and fall times measured from 10% to 90%.Power dissipation measured with encode at rated speed and a dc analog input. (Outputs Static, IVDD = 0.)SNR/harmonics based on an analog input voltage of –0.5 dBFS referenced to a 2V full-scale input range.
Typical θJA for LQFP package = 50°C/W.

PIN CONFIGURATION
PIN FUNCTION DESCRIPTIONS
DEFINITION OF SPECIFICATIONS
Analog Bandwidth (Small Signal)
The analog input frequency at which the spectral power of the
fundamental frequency (as determined by the FFT analysis) is
reduced by 3 dB.
Aperture Delay
The delay between a differential crossing of ENCODE and
ENCODE and the instant at which the analog input is sampled.
Aperture Uncertainty (Jitter)
The sample-to-sample variation in aperture delay.
Differential Nonlinearity
The deviation of any code from an ideal 1 LSB step.
Encode Pulsewidth/Duty Cycle
Pulsewidth high is the minimum amount of time that the
ENCODE pulse should be left in Logic “1” state to achieve
rated performance; pulsewidth low is the minimum time
ENCODE pulse should be left in low state. At a given clock
rate, these specs define an acceptable Encode duty cycle.
Minimum Conversion Rate
The encode rate at which the SNR of the lowest analog signal
frequency drops by no more than 3 dB below the guaranteed
limit.
Maximum Conversion Rate
The encode rate at which parametric testing is performed.
Output Propagation Delay
The delay between a differential crossing of ENCODE and
ENCODE and the time when all output data bits are within
valid logic levels.
Power Supply Rejection Ratio
The ratio of a change in input offset voltage to a change in
power supply voltage.
Signal-to-Noise Plus Distortion (SINAD)
The ratio of the rms signal amplitude (set at 1 dB below full
scale) to the rms value of the sum of all other spectral compo-
nents, including harmonics but excluding dc.
Spurious-Free Dynamic Range (SFDR)
The ratio of the rms signal amplitude to the rms value of the
peak spurious spectral component. The peak spurious compo-
nent may or may not be a harmonic. May be reported in dBc
(i.e., degrades as signal level is lowered), or in dBFS (always
related back to converter full scale).
Two-Tone Intermodulation Distortion Rejection
The ratio of the rms value of either input tone to the rms value
of the worst third order intermodulation product; reported in dBc.

Figure 2.Equivalent Voltage Reference Input Circuit
Figure 3.Equivalent Voltage Reference Output Circuit
Two-Tone SFDR
The ratio of the rms value of either input tone to the rms value
of the peak spurious component. The peak spurious component
may or may not be an IMD product. May be reported in dBc
(i.e., degrades as signal levels is lowered), or in dBFS (always
related back to converter full scale).
Worst Harmonic
The ratio of the rms signal amplitude to the rms value of the
worst harmonic component, reported in dBc.
