The AD7549 is a monolithic dual 12‑bit current‑output DAC available in a 0.3 in wide 20‑pin DIP or a 20‑terminal surface‑mount package. Both DAC channels provide four‑quadrant multiplication with separate reference inputs and feedback resistors, enabling precise matching and tracking.
Typical applications include programmable filters, audio systems, automatic test equipment, micro‑computer based process control, and programmable power supplies. The device operates over a wide temperature range and includes features such as latch‑up protection, low gain error (≤3 LSB), and 1 % DAC ladder resistance matching.
