LVDS DAC Features SFDR Of 76 dBc

Claiming an industry benchmark, the 16-bit MAX5888 LVDS D/A converter has a spurious-free dynamic range (SFDR) of 76 dBc at a 40 MHz output. With an output frequency of 61 MHz (3.8 MHz channel), adjacent-channel leakage ratio (ACLR) is 76 dBc. The device operates from a single 3.3V supply and supports update rates of 500 Msamples/s. Power dissipation is 250 mW at 500 Msamples/s and 130 mW typical at 100 Msamples/s. The converter employs a current-steering architecture that supports a full-scale output current range of 2 mA to 20 mA and allows a differential output voltage swing between 0.1 and 1 Vp-p. Other features include: an integrated 1.25V bandgap reference and control amplifier; differential, LVDS-compatible digital and clock inputs; and a separate reference input pin. Available in a 68-pin QFN-EP with an operating temperature range from -40°C to +85°C, prices start at $34.50 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
