描述 Description

The DAC3152/DAC3162 is a low-power, low-latency, high-dynamic-range, dual-channel, 10-/12-bit, pin-compatible family of digital-to-analog converters (DACs) with a sample rate as high as 500 MSPS.The device simplicity (no software required), low latency, and low power simplify the design of complex systems. The DACs interface seamlessly with the high-performance TRF370333 analog quadrature modulator for direct upconversion architectures.Digital data for both DAC channels is interleaved through a single LVDS data bus with on-chip termination. The high input rate of the devices allows the processing of wide-bandwidth signals.The devices are characterized for operation over the entire industrial temperature range of –40°C to 85°C and are available in a small 48-pin 7-mm × 7-mm QFN package.The low power, small size, speed, superior crosstalk, simplicity, and low latency of the DAC3152/DAC3162 make them an attractive fit for a variety of applications.
