Analog Devices Inc. AD9742ARUZ Digital-to-Analog Converter

The AD9742ARUZ is a high-performance, 14-bit digital-to-analog converter (DAC) from Analog Devices Inc., designed to meet the demanding requirements of communication systems and signal generation applications. This DAC is part of a family of pin-compatible DACs, including the 10-bit AD9708, the 12-bit AD9762, the 14-bit AD9742, and the 16-bit AD9764, offering a range of resolution options for system design flexibility.

The AD9742ARUZ boasts an impressive update rate of 210 MSPS, making it an excellent choice for applications requiring high-speed data conversion. Its architecture is based on a segmented current-steering design, which ensures high-speed performance and excellent static linearity. The integral nonlinearity (INL) is typically within ±1 LSB, while the differential nonlinearity (DNL) is also typically within ±1 LSB, ensuring accurate and consistent performance over the entire operating range.

This DAC operates from a single 3.3 V power supply and features an on-chip 1.20 V reference, though it also supports an external reference input for enhanced flexibility. The digital interface is CMOS compatible and supports double data rate (DDR) operation, providing efficient data transfer to the DAC core.

Enclosed in a compact 28-lead TSSOP package, the AD9742ARUZ is designed to minimize board space and is suitable for use in a wide variety of applications. These include wireless base stations for GSM, CDMA, WCDMA, and TD-SCDMA systems, broadband wireless access systems, cable modem termination systems, and direct digital synthesis (DDS) systems.
