DAC1617D1G0集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

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.
