The AD9122BCPZ is a dual 16-bit high dynamic range Digital-to-analog Converter (DAC) provides a sample rate of 1230MSPS, permitting multicarrier generation up to the Nyquist frequency. It includes features optimized for direct conversion transmits applications. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators, such as the ADL537x F-MOD series from Analog Devices Inc. A 4-wire serial port interface provides for programming/read-back of many internal parameters. Full-scale output current can be programmed over a range of 8.7 to 31.7mA.

• Flexible LVDS interface allows word, byte or nibble load
• Gain, DC offset and phase adjustment for sideband suppression
• Multiple chip synchronization interfaces
• High performance, low noise PLL clock multiplier
• Digital inverse sinc filter

The AD5697R, a member of the nanoDAC+™ family, is a low power, dual, 12-bit buffered voltage output digital-to-analog converter (DAC). The device includes a 2.5 V, 2 ppm/°C internal reference (enabled by default) and a gain select pin giving a full-scale output of 2.5 V (gain = 1) or 5 V (gain = 2). The AD5697R operates from a single 2.7 V to 5.5 V supply, is guaranteed monotonic by design, and exhibits less than 0.1% FSR gain error and 1.5 mV offset error performance. The device is available in a 3 mm × 3 mm LFCSP and a TSSOP package.

The AD5697R also incorporates a power-on reset circuit and a RSTSEL pin that ensure that the DAC outputs power up to zero scale or midscale and remain there until a valid write takes place. It contains a per channel power-down feature that reduces the current consumption of the device to 4 µA at 3 V while in power-down mode.

The AD5697R uses a versatile 2-wire serial interface that operates at clock rates up to 400 kHz and includes a VLOGIC pin intended for 1.8 V/3 V/5 V logic.
