Overview
The AD9148BBPZRL is a quad, 16-bit, high dynamic range digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is designed to provide a sample rate of 1000 MSPS, making it highly suitable for direct conversion transmit applications. It features optimized performance for interfacing with analog quadrature modulators and includes various compensation mechanisms for gain, phase, and offset. The AD9148BBPZRL operates from 1.8 V and 3.3 V supplies, with a total power consumption of 3 W at the maximum sample rate. It is enclosed in a 196-ball chip scale package ball grid array (BGA) with the option of an attached heat spreader.
