16-Bit, Ultra Precise, Fast Settling VOUT DAC
The LTC1821 is a 16‑bit parallel‑input multiplying DAC that operates from a +4.5 V to +15 V supply and provides bipolar output up to ±10 V. It features 2 µs settling to 0.0015 % of full‑scale, ultra‑low glitch impulse of 2 nV·s, and 16‑bit resolution.
The device is supplied in a 36‑lead SSOP package and includes on‑chip 4‑quadrant resistors for precise gain and offset adjustment. Detailed electrical characteristics, pin functions, and typical performance graphs are provided for design integration.
