AD9139BCPZ

Overview

The AD9139BCPZ is a 16-bit, high dynamic range digital-to-analog converter (DAC) from Analog Devices Inc., operating at a maximum sample rate of 1600 MSPS. It utilizes TxDAC+ architecture to generate multicarrier signals up to the Nyquist frequency. The device features selectable 1× or 2× interpolation filters and supports input signal bandwidths up to 575 MHz. Key electrical specifications include a differential nonlinearity (DNL) of ±2.1 LSB and an integral nonlinearity (INL) of ±3.7 LSB. It operates with analog supply voltages of 3.13 V to 3.47 V and digital supplies of 1.7 V to 1.9 V. The component is housed in a 72-lead LFCSP package.
