AD9172BBPZ

The AD9172BBPZ from Analog Devices is a high-performance, dual 16-bit digital-to-analog converter (DAC) designed for RF applications, supporting sample rates up to 12.6 GSPS. This device integrates channelizer DSP capabilities, including three bypassable complex data input channels per RF DAC, each with an independent NCO, configurable gain stage, and interpolation filter. This architecture enables flexible multiband frequency planning, allowing multiple carriers to be synthesized simultaneously.

The AD9172BBPZ features an 8-lane JESD204B interface operating at 15 Gbps per lane, facilitating high-speed data transfer. It also supports ultrawide bandwidth bypass modes for applications requiring maximum instantaneous bandwidth. The device is housed in a 144-ball BGA_ED package with a 10mm x 10mm footprint and operates within an industrial temperature range of -40°C to +85°C.

Key electrical characteristics include a maximum complex input data rate of 1.5 GSPS per channel and low power consumption, rated at 2.55 W at 12 GSPS in dual-channel mode. The DAC exhibits excellent performance with 2-tone intermodulation distortion (IMD) of -83 dBc and spurious free dynamic range (SFDR) below -80 dBc at 1.8 GHz.

Applications for the AD9172BBPZ include wireless communications infrastructure, multiband base station radios, microwave/E-band backhaul systems, instrumentation, automatic test equipment (ATE), radars, and jammers. Its design supports single-band and multiband use cases, making it a versatile component for advanced RF systems.
