DAC5672 数模转换器
DAC5672 说明
The DAC5672 is a monolithic, dual-channel, 14-bit, high-speed DAC with on-chip voltage reference.
Operating with update rates of up to 275 MSPS, the DAC5672 offers exceptional dynamic performance, tight-gain, and offset matching characteristics that make it suitable in either I/Q baseband or direct IF communication applications.
Each DAC has a high-impedance, differential-current output, suitable for single-ended or differential analog-output configurations. External resistors allow scaling the full-scale output current for each DAC separately or together, typically between 2 mA and 20 mA. An accurate on-chip voltage reference is temperature-compensated and delivers a stable 1.2-V reference voltage. Optionally, an external reference may be used.
