Description

The 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. The AD9042 runs off of a single +5 V supply and provides CMOS-compatible digital outputs at 41MSPS.

Designed specifically to address the needs of wideband, multichannel receivers, the AD9042 maintains 80 dB spurious-free dynamic range (SFDR) over a bandwidth of 20MHz.  Noise performance is also exceptional; typical signal-to-noise ratio is 68 dB. The AD9042 is built on Analog Devices' high speed complementary bipolar process (XFCB) and uses an innovative multipass architecture.  Units are packaged in a 28-pin DIP; this customcofired ceramic package forms a multilayer substrate to which internal bypass capacitors and the 9042 die are attached and a 44-pin TQFP low profile surface mount 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 factory for military grade product options.
