PRODUCT DE SCRIPT ION
T he AD9042 is a high speed, high performance, low power,
monolithic 12-bit analog-to-digital converter. All necessary
functions, including track-and-hold (T /H) and reference are
included on chip to provide a complete conversion solution.
T he AD9042 runs off of a single +5 V supply and provides
CMOS-compatible digital outputs at 41 MSPS.
Designed specifically to address the needs of wideband,
multichannel receivers, the AD9042 maintains 80 dB
spurious-free dynamic range (SFDR) over a bandwidth of
20 MHz. Noise performance is also exceptional; typical
signal-to-noise ratio is 68 dB.
T he AD9042 is built on Analog Devices’ high speed complemen-
tary bipolar process (X FCB) and uses an innovative multipass
architecture. Units are packaged in a 28-pin DIP; this custom

cofired ceramic package forms a multilayer substrate to which
internal bypass capacitors and the 9042 die are attached and a
44-pin T QFP low profile surface mount package. T he AD9042
industrial grade is specified from –40

C to +85
°
C. However,
the AD9042 was designed to perform over the full military
temperature range (–55
