AD9106BCPZ

The AD9106BCPZ is a quad, low power, 12-bit digital-to-analog converter (DAC) from Analog Devices, capable of operating at up to 180 MSPS. It integrates a direct digital synthesizer (DDS) with a 24-bit tuning word providing 10.8 Hz/LSB frequency resolution, and 4096 × 12-bit on-chip pattern memory for complex waveform generation. The device features a segmented DAC architecture, SPI data interface, and supports both external and internal voltage references. Output is current-unbuffered and differential, with a full-scale output current up to 8 mA at 3.3 V supply. Typical settling time is 31.2 ns, and spurious-free dynamic range (SFDR) is 86 dBc at 10 MHz output. Phase noise at 1 kHz offset is -140 dBc/Hz. Power dissipation is 315.25 mW typical at 180 MSPS, with a power-down mode consuming less than 5 mW. The supply voltage range is 1.7 V to 3.6 V (note datasheet specifies 1.8 V to 3.3 V). Operating temperature range is -40°C to 85°C. The device is packaged in a 32-WFQFN exposed pad, CSP (32-LFCSP 5x5 mm) for surface mount assembly. Typical applications include medical instrumentation, ultrasound transducer excitation, portable instrumentation, and signal generators.
