Analog Devices Inc. Analog Devices AD9139 16 位数模转换器

Analog Devices AD9139 是一款 16 位、高动态范围数模转换器(DAC)，提供达 1600 MSPS 的采样速率，可以产生高达奈奎斯特频率的多载波。AD9139 TxDAC+® 的特性针对宽带通信应用而优化，集成 1 倍和 2 倍插值、基于 DLL 的高速接口、采样错误检测以及奇偶校验。3 线式串行端口接口(SPI)允许对许多内部参数进行编程和回读。满量程输出电流可以在 9 mA 至 33 mA 范围上进行编程。AD9139 适用于宽带通信、发射分集/MIMO、仪器仪表、自动测试设备等。

The AD9139 TxDAC+® includes features optimized for wideband communication applications, including 1× and 2× interpolation, a Delay-Locked Loop (DLL) powered high-speed interface, sample error detection, and parity detection. A 3-wire serial port interface provides for the programming/readback of many internal parameters. A full-scale output current can be programmed over a range of 9mA up to 33mA. The AD9139 is ideal for wideband communications, transmit diversity/MIMO, instrumentation, and automated test equipment.
