Features, Applications

FEATURES 41 MSPS Minimum Sample Rate 80 dB Spurious-Free Dynamic Range 595 mW Power Dissipation Single +5 V Supply On-Chip T/H and Reference Twos Complement Output Format CMOS-Compatible Output Levels APPLICATIONS Cellular/PCS Base Stations GPS Anti-Jamming Receivers Communications Receivers Spectrum Analyzers Electro-Optics Medical Imaging ATE PRODUCT DESCRIPTION

The 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 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. The AD9042 is built on Analog Devices' high speed complementary bipolar process (XFCB) and uses an innovative multipass architecture. Units are packaged 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 TQFP low profile surface mount package. The AD9042 industrial grade is specified from to +85C. However, the AD9042 was designed to perform over the full military temperature range to +125C); consult factory for military grade product options.

1. Guaranteed sample rate is 41 MSPS. 2. Dynamic performance specified over entire Nyquist band; spurious signals typ. 80 dBc for 1 dBFS input signals. 3. Low power dissipation: 595 mW off a single +5 V supply. 4. Reference and track-and-hold included on chip. 5. Packaged in 28-pin ceramic DIP and 44-pin TQFP.
