DAC161S997RGHR

General description
The DAC1617D1G0 is a high-speed 16-bit dual channel Digital-to-Analog Converter (DAC) with selectable x2, x4 and x8 interpolation filters.
The device is optimized for multi-carrier and broadband wireless transmitters at sample rates of up to 1 Gsps. Supplied from a 3.3 V and a 1.8 V source, the DAC1617D1G0 integrates a differential scalable output current up to 34 mA.
