Linear Technology LTC1257 Datasheet
The LTC1257 is a complete single‑supply, 12‑bit voltage‑output DAC offered in an 8‑pin SO‑8 package. It includes an internal 2.048 V reference, a buffered output stage, and a three‑wire cascaded serial interface, making it suitable for battery‑powered and space‑constrained designs. The device operates from a wide supply range (4.75 V to 15.75 V) and draws low current (typical 350 µA at 5 V).
The datasheet details absolute maximum ratings, electrical characteristics, pin assignments, timing diagrams, and typical performance graphs. It also describes typical applications such as daisy‑chained DAC arrays and external‑reference configurations, along with mechanical package dimensions for PCB layout.
