The DAC1617D1G0HN is a high-speed 16-bit dual channel Digital-to-Analog Converter (DAC) with selectable x2, x4 and x8 interpolating filters 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 DAC1617D1G0HN integrates a differential scalable output current up to 34 mA. The DAC1617D1G0HN is capable of meeting multi-carrier GSM specifications. The Serial Peripheral Interface (SPI) provides full control of the DAC1617D1G0HN. The DAC1617D1G0HN integrates a Low Voltage Differential Signaling (LVDS) Double Data Rate (DDR) receiver interface, with an on-chip 100 Ohm termination.
