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， 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 （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.
