PRODUCT DESCRIPTION
The AD9026 and AD9027 are high speed, high performance,
monolithic 12-bit analog-to-digital converters. All necessary
functions, including track-and-hold (T/H) and reference are
included on chip to provide complete conversion solutions. The
AD9026 features TTL logic for digital inputs and outputs; the
AD9027 uses ECL logic including differential ECL encode.
Both the TTL and ECL converters are available at 25.6 Msps
(A grade) and 31 Msps (B grade) production tested encode
rates.
The on-chip T/H has a 150 MHz input bandwidth and is de-
signed to provide good dynamic performance for input frequen-
cies above Nyquist. This feature is necessary for IF-to-digital
conversion applications in which the A/D converter is used in
an undersampling mode. In addition, wide spurious-free dy-
namic range over the entire Nyquist bandwidth makes the
AD9026 and AD9027 well suited for multichannel transceiver
applications; both 31 Msps converters can digitize bandwidths
up to 15 MHz.
The AD9026 and AD9027 are built on a trench isolated bipolar
process and use an innovative multipass architecture (see Func-
tional Block Diagram). Both parts are packaged in a 28-pin
ceramic DIP; the custom cofired ceramic package forms a multi-
layer substrate to which internal bypass capacitors and the ADC
die are attached. Both the AD9026 and the AD9027 are speci-
fied to operate over the industrial (–25
°
C to +85
°
C measured
at case) temperature range.
PRODUCT HIGHLIGHTS
1. At 31 Msps (B grade devices) conversion rate, the converters
can digitize 15 MHz of spectrum.
2. On-chip T/H provides > 70 dB spurious-free dynamic range
over entire Nyquist band.
3. On-chip reference sets a 2.048 V p-p input voltage range
centered at 0 V.
4. AD9026 outputs connect directly to TTL logic; no ECL-to-
TTL chips required.
5. AD9027 ECL outputs offer lowest noise alternative for sys-
tem designs that prefer reduced output voltage swings.
