AD9251BCPZ-65

The AD9251BCPZ-65 is a 14-bit, 65 MSPS dual analog-to-digital converter (ADC) from Analog Devices. It employs a pipelined architecture with two simultaneous sampling channels, each with a differential input and a 700 MHz analog input bandwidth. The device achieves a typical signal-to-noise ratio (SNR) of 74.3 dBFS at a 9.7 MHz input and 71.5 dBFS at a 200 MHz input, with a spurious-free dynamic range (SFDR) of 93 dBc and 80 dBc respectively.

The ADC operates from a 1.7 V to 3.6 V analog supply and a 1.7 V to 3.6 V digital output supply, with low power dissipation of 33 mW per channel at 20 MSPS and 73 mW per channel at 80 MSPS. It includes an on-chip voltage reference and sample-and-hold circuit, and supports external or internal reference. The digital output is available via a parallel interface with offset binary, gray code, or twos complement data formats.

The AD9251BCPZ-65 is housed in a 64-lead LFCSP-VQ (9x9 mm) package with an exposed pad for surface mount assembly. It is specified for operation over the -40°C to +85°C temperature range, making it suitable for communications, instrumentation, and medical imaging applications.
