AD9142BCPZ

The AD9142BCPZ is a dual 16-bit digital-to-analog converter (DAC) from Analog Devices, designed for high-speed applications with a maximum sampling rate of 1600 MSPS. It utilizes an oversampling interpolating DAC architecture and provides a current unbuffered output with differential capability. The device features a flexible 16-bit LVDS parallel data interface and supports both external and internal voltage references.

Key electrical specifications include a typical settling time of 20 ns, typical INL of ±3.7 LSB and DNL of ±2.1 LSB, and a typical SFDR greater than 85 dBc at 300 MHz bandwidth in zero-IF mode. The AD9142 achieves a 6-carrier GSM ACLR of 79 dBc at 200 MHz IF. It operates from an analog supply voltage range of 1.7V to 1.9V and is specified over the industrial temperature range of -40°C to +85°C.

The device is housed in a 72-lead LFCSP package (72-LFCSP-VQ, 10x10 mm) with an exposed pad for thermal management. It is surface-mountable and suitable for high-density PCB designs. The AD9142 is intended for wireless communications infrastructure, wideband communications, and instrumentation applications.
