Linear Technology LTC1821 Datasheet
The LTC1821 is a 16‑bit, 4‑quadrant multiplying DAC that operates from analog supply voltages of +5 V to +15 V and supports both unipolar (0‑10 V) and bipolar (±10 V) output modes. It offers fast 2 µs settling to 0.0015 % of full scale, low‑glitch impulse (2 nV·s), and low noise (13 nV/√Hz at zero scale).
The document lists absolute maximum ratings, detailed electrical characteristics, pin descriptions, truth table, package dimensions (36‑lead SSOP), and related Linear Technology parts. Typical performance graphs illustrate settling time, glitch impulse, and linearity across supply voltages.
