Analog Devices AD538 Datasheet
The AD538 provides real‑time analog computation for multiplication, division and exponentiation. It features a wide 1000:1 input dynamic range, low input offsets, and an error as low as 0.25 % of reading. On‑chip reference voltages of +2 V and +10 V allow scaling without external components.
The device is supplied in an 18‑lead TO‑118 hermetic DIP and operates from +4.5 V to +18 V. It is available in industrial (‑25 °C to +85 °C) and military (‑55 °C to +125 °C) temperature grades, with typical bandwidth of 400 kHz.
