AD9864 is a low-frequency signal acquisition chip launched by ADI. It uses a 48-lead LFCSP package and works at a voltage of 2.7V to 3.6V. It integrates LO and sampling clock generators and supports 16-bit or 24-bit serial digital output.
The AD9864 from Analog Devices digitizes a low‑level IF signal ranging from 10 MHz to 300 MHz with a selectable bandwidth of 6.8 kHz to 270 kHz. It integrates a low‑noise amplifier, mixer, band‑pass Z‑A ADC, and programmable decimation filter, plus on‑chip LO and clock synthesizers.
The device operates from a single 2.7 V‑3.6 V supply, consumes about 17 mA in normal mode, and provides 16‑ or 24‑bit I/Q data via a synchronous serial interface. It is offered in a 48‑lead LFCSP package and includes programmable gain control and automatic gain control for flexible radio applications.
