The AD9244 is a 14-bit, 40 MSPS/65 MSPS A/D converter with features such as low power consumption, on-chip reference voltage, and sample-and-hold circuit. It has a 750 MHz analog input bandwidth, SNR greater than 73 dBc to Nyquist @ 65 MSPS, and SFDR greater than 86 dBc to Nyquist @ 65 MSPS.
The AD9244 is a monolithic, single‑supply 14‑bit analog‑to‑digital converter offering 40 MSPS or 65 MSPS sampling rates. It integrates a high‑performance sample‑and‑hold amplifier and an on‑chip voltage reference, and guarantees no missing codes over the full temperature range.
Key features include low power operation (550 mW at 65 MSPS), 750 MHz analog input bandwidth, differential clock inputs, and flexible digital output formats (straight binary or two's complement). The device is supplied in a 48‑lead low‑profile quad flat package and is rated for industrial temperature ranges.
