AD9248BSTZ-65

The AD9248BSTZ-65 is a dual, 14-bit analog-to-digital converter (ADC) from Analog Devices, designed for high-speed data acquisition applications. It supports sampling rates of up to 65 MSPS per channel, making it suitable for demanding signal processing tasks.

Key electrical specifications include a signal-to-noise ratio (SNR) of 71.6 dB and a spurious-free dynamic range (SFDR) of 80.5 dBc, both measured to Nyquist at 65 MSPS. The device operates from a single 2.25V to 3.6V supply, consuming a low power of 300 mW per channel at its maximum speed. It features a wide differential input bandwidth of 500 MHz and accepts input ranges from 1 V p-p to 2 V p-p.

This ADC utilizes a multistage differential pipelined architecture with error correction logic to ensure 14-bit accuracy and guarantee no missing codes. It offers flexible analog input options, including single-ended applications, and supports both offset binary and twos complement data formats. A clock duty cycle stabilizer is integrated to maintain performance over variations in clock duty cycle.

The AD9248BSTZ-65 is housed in a 64-LQFP (7x7 mm) surface-mount package, operating across a temperature range of -40°C to 85°C. Its features make it suitable for applications such as ultrasound equipment, direct conversion receivers, and battery-powered instruments.
