AD9626BCPZ-250

The AD9626BCPZ-250 is a 12-bit monolithic sampling analog-to-digital converter (ADC) from Analog Devices, designed for high-speed data acquisition applications. It operates at a maximum sampling rate of 250 MSPS and uses a pipelined architecture with a sample-and-hold front end.

Key electrical specifications include a signal-to-noise ratio (SNR) of 64.8 dBFS and an effective number of bits (ENOB) of 10.5 bits, both measured at a 70 MHz input frequency and 250 MSPS. The spurious-free dynamic range (SFDR) is 80 dBc under the same conditions. The device features a 700 MHz full power analog bandwidth and a programmable input voltage range of 1.0V to 1.5V, with a nominal 1.25V setting.

The ADC is housed in a 56-lead LFCSP-VQ (8x8 mm) surface-mount package and operates over a -40°C to +85°C temperature range. It requires a 1.8V analog and digital supply and includes an internal voltage reference. The data interface is LVDS parallel, supporting single data port operation up to 250 MHz or interleaved dual port at half the sample rate.
