The AD9732 was primarily designed for demanding communications systems applications where maximum spurious-free dynamic range (SFDR) is required at high throughput rates. The proliferation of digital communications into base station and high volume subscriber-end markets has created a demand for high performance bipolar DACs delivered at CMOS associated levels of power dissipation and cost. The AD9732 is the answer to that demand. Optimized for direct digital synthesis (DDS) and digital modulator waveform reconstruction, the AD9732 provides >50 dB of wideband harmonic suppression over the dc to 80 MHz analog output bandwidth. This signal bandwidth addresses the transmit REFIN CLOCK INTERNAL VOLTAGE REFERENCE RSET REFOUT CONTROL AMP AD9732 CONTROL AMP OUT TE CONTROL AMP IN DIGITAL +VS spectrum in many of the emerging digital communications applications where signal purity is critical. Narrowband (± 1 MHz window), the AD9732 provides an SFDR of greater than 75 dB. This level of wideband and narrowband ac performance, coupled with its 200 MSPS throughput rate, enables the AD9732 to present outstanding value in the high speed DAC function. The AD9732 is packaged in a 28-lead SSOP and is specified to operate over the extended industrial temperature range of –40°C to +85°C. Digital inputs and clock are positive-ECL compatible. REV.
