CDCM7005 - Recommended clocking solution, providing low jitter clock outputs to maximize converter performance

DAC5662A 说明

The DAC5662A is a monolithic, dual-channel 12-bit high-speed digital-to-analog converter (DAC) with on-chip voltage reference.

Operating with update rates of up to 275 MSPS, the DAC5662A offers exceptional dynamic performance and 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.
