This document is the AD538 datasheet, which introduces the features of this product.
The AD538 provides real‑time analog multiplication, division and exponentiation using resistor‑programmable powers and on‑chip voltage references (+2 V and +10 V). It features low input offsets (<100 µV), low error (0.25 % of reading) and a wide input dynamic range of 1000:1.
The device operates from a 4.5 V to +18 V supply, is available in several accuracy grades (A, B, S) and packaged in an 18‑lead TO‑118 hermetic side‑brazed ceramic DIP. Typical bandwidth is 400 kHz for one‑quadrant multiplication/division, with output currents of 5 mA to 10 mA.
