AD9139BCPZ

The AD9139 is a 16-bit, high dynamic range digital-to-analog converter with a maximum sample rate of 1600 MSPS, enabling multicarrier generation up to the Nyquist frequency. It includes a selectable 1× or 2× interpolation filter, a flexible 16-bit LVDS interface, and a low-power architecture. Key electrical specifications include 16-bit resolution, typical settling time of 20 ns, SFDR greater than 85 dBc (300 MHz bandwidth, zero IF), and ACLR of 79 dBc (6-carrier GSM, 200 MHz IF). The input signal bandwidth extends to 575 MHz. Power dissipation is 700 mW typical at 1230 MSPS. The device requires two supply voltages: digital core (1.7V to 1.9V) and I/O (3.13V to 3.47V).

The AD9139BCPZ is designed for wireless communication applications such as 3G/4G and MC-GSM base stations, wideband repeaters, and software defined radios. It also suits instrumentation and automated test equipment. The converter uses a current source architecture with differential current-unbuffered output, supports external or internal reference, and accepts data in 2s complement or binary format.

Packaged in a 72-lead LFCSP (10x10mm) with exposed pad, the device is surface mount compatible. Operating temperature range is -40°C to +85°C. The part is RoHS3 compliant, with MSL level 1 (unlimited) and REACH unaffected status, though these compliance attributes have low confidence.
