AD9218 is a dual-channel 10-bit, 40/65/80/105 MSPS A/D converter. It features low power consumption, on-chip reference and track/holds, 300 MHz analog bandwidth, 1 V p-p or 2 V p-p analog input range, etc.
The AD9218 is a dual 10‑bit ADC that operates from a single 3 V supply (2.7 V‑3.6 V) and provides up to 105 MSPS conversion rate per channel. It features on‑chip reference, track‑and‑hold, and flexible output formats (two’s‑complement or offset binary). The device is supplied in a 48‑lead LQFP package (7 × 7 mm) and is rated for industrial temperature range.
Key features include low power dissipation (275 mW per channel at 105 MSPS), 300 MHz analog bandwidth, -75 dBc channel crosstalk, and selectable input ranges of 1 V p‑p or 2 V p‑p. Detailed specifications cover resolution, accuracy, power supply characteristics, pin functions, and timing parameters.
