DAC34H84IZAYR

The DAC34H84IZAYR from Texas Instruments is a high-speed, quad-channel, 16-bit digital-to-analog converter (DAC) capable of sample rates up to 1.25 GSPS. This device is designed for complex transmit architectures, featuring selectable 2x to 16x digital interpolation filters with over 90 dB of stop-band attenuation, simplifying data interfaces and reconstruction filters.

Key electrical specifications include a very low power consumption of 1.4 W at 1.25 GSPS, a flexible on-chip complex mixing capability with independent fine mixers and 32-bit NCOs, and a high-performance, low-jitter clock multiplying PLL. The DAC34H84IZAYR supports a 32-bit DDR flexible LVDS input data bus and includes an 8-sample input FIFO. It offers a scalable output current from 10mA to 30mA.

This DAC is housed in a 196-ball, 12x12mm NFBGA package, suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C. The device features digital I and Q correction, gain, phase, offset, and group delay correction, as well as digital inverse sinc filters.

With its high dynamic range and integrated features, the DAC34H84IZAYR is well-suited for applications requiring high-speed signal generation and processing.
