DAC3482 Dual-Channel DACs

Texas Instruments offers the DAC3482 dual-channel, 16-bit, 1.25 GSPS, 2x to 16x interpolating digital-to-analog converters (DACs)

Image of Texas Instruments' DAC3482 Dual-Channel DACsTexas Instruments' DAC3482 is a very low power, high dynamic range, dual-channel, 16-bit digital-to-analog converter (DAC) with a sample rate as high as 1.25 GSPS.

The device includes features that simplify the design of complex transmit architectures: 2x to 16x digital interpolation filters with over 90 dB of stop-band attenuation simplify the data interface and reconstruction filters. A complex mixer allows flexible carrier placement. A high-performance low jitter clock multiplier simplifies clocking of the device without significant impact on the dynamic range. The digital quadrature modulator correction (QMC) enables complete IQ compensation for gain, offset, phase, and group delay between channels in direct up-conversion applications.

Digital data is input to the device through a flexible LVDS data bus with on-chip termination. Data can be input either word-wide or byte-wide. The device includes a FIFO, data pattern checker, and parity test to ease the input interface. The interface also allows full synchronization of multiple devices.

The device is characterized for operation over the entire industrial temperature range of -40°C to +85°C and is available in a very small 88-pin 9 mm x 9 mm WQFN-MR package or 196-ball 12 mm x 12 mm NFBGA package.

Very low power, small size, superior crosstalk, high dynamic range, and features of the DAC3482 make it an ideal fit for today’s communication systems.
