AD9255BCPZ-80

The AD9255BCPZ-80 is a high-performance 14-bit Analog-to-Digital Converter (ADC) designed by Analog Devices. It supports sampling rates of up to 125 MSPS, with alternate rates of 105 MSPS and 80 MSPS available. This ADC operates from a single 1.8V analog supply and can utilize a separate 1.8V digital output supply for CMOS or LVDS outputs.

Key electrical specifications include a Signal-to-Noise Ratio (SNR) of 78.3 dBFS at 70 MHz and 125 MSPS, and a Spurious-Free Dynamic Range (SFDR) of 93 dBc under the same conditions. The device features a low power consumption of 371 mW at 125 MSPS. It includes an integer 1-to-8 input clock divider and supports IF sampling frequencies up to 300 MHz. The analog input range is flexible, from 1 V p-p to 2 V p-p, with a differential input bandwidth of 650 MHz.

Applications for the AD9255BCPZ-80 include communications, such as multimode digital receivers (3G) for GSM, EDGE, W-CDMA, LTE, CDMA2000, WiMAX, and TD-SCDMA. It is also suitable for smart antenna systems, general-purpose software radios, broadband data applications, and ultrasound equipment. The ADC offers features like an optional on-chip dither for improved SFDR, a programmable internal voltage reference, and integrated sample-and-hold inputs. A serial port control allows for user configuration of data formatting, clock duty cycle stabilization, power-down modes, and test modes. The device is pin-compatible with the AD9265 for easy migration to 16-bit solutions.
