GENERAL DESCRIPTION
The AD9042 is a high speed, high performance, low power,
monolithic 12-bit analog-to-digital converter (ADC). All
necessary functions, including track-and-hold (T/H) and
reference, are included on chip to provide a complete conversion
solution. The AD9042 operates from a single 5 V supply and
provides CMOS-compatible digital outputs at 41 MSPS.
Designed specifically to address the needs of wideband, multi-
channel 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
(SNR) is 68 dB.
The AD9042 is built on a high speed complementary bipolar
process (XFCB) used by Analog Devices, Inc., and uses an
innovative multipass architecture. Units are packaged in a
44-lead LQFP low profile quad flat package. The 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°C to +125°C); consult the factory for
military grade product options.
