Texas Instruments DAC3482 Dual-Channel, 16-bit DAC
Texas Instruments DAC3482 Dual-Channel, 16-bit Digital-to-Analog Converter (DAC) is a very low power, high dynamic range device with a sample rate as high as 1.25GSPS. TI DAC3482 includes features that simplify the design of complex transmit architectures: 2x to 16x digital interpolation filters with over 90dB 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.
