With DNL typically less than 0.5 LSB and 20 ns transient re-
sponse settling time, the AD9023 provides excellent results
when low frequency analog inputs must be over-sampled (such
as CCD digitization). The full-scale analog input is
±
1 V with a
300
input impedance. The analog input can be driven directly
from the signal source, or can be buffered by the AD96xx series
of low noise, low distortion buffer amplifiers.
All timing is internal to the AD9023; the clock signal initiates
the conversion cycle. For best results, the encode command
should contain as little jitter as possible. High speed layout prac-
tices must be followed to ensure optimum A/D performance.
The AD9023 is built on a trench isolated bipolar process and
utilizes an innovative multipass architecture (see the block dia-
gram). The unit is packaged in 28-pin ceramic DIPs and
gullwing surface mount packages. The AD9023 is specified to
operate over the industrial (–25
°
C to +85
°
C) and extended
(–55
°
C to +125
°
C) temperature ranges.

PRODUCT DESCRIPTION
The AD9023 is a high speed, high performance, monolithic 12-
bit analog-to-digital converter. All necessary functions, includ-
ing track-and-hold (T/H) and reference, are included on chip to
provide a complete conversion solution. It is a companion unit
to the AD9022; the primary difference between the two is that
all logic for the AD9022 is TTL compatible, while the AD9023
utilizes ECL logic for digital inputs and outputs. Pinouts for the
two parts are nearly identical.
Operating from +5 V and –5.2 V supplies, the AD9023 provides
excellent dynamic performance. Sampling at 20 Msps with
A
IN
= 1 MHz, the spurious-free dynamic range (SFDR) is typi-
cally 74 dB; with A
IN
= 9.6 MHz, SFDR is 72 dB. SNR is typi-
cally 65 dB.
The on-board T/H has a 110 MHz bandwidth and, more impor-
tantly, is designed to provide excellent dynamic performance for
analog input frequencies above Nyquist. This feature is neces-
sary in many undersampling signal processing applications, such
as in direct IF-to-digital conversion.
To maintain dynamic performance at higher IFs, monolithic RF
track-and-holds (such as the AD9100 and AD9101 Samplifier)
can be used with the AD9023 to process signals up to and
beyond 70 MHz.
