The AD538BD is a monolithic real-time analog computational unit (ACU) from Analog Devices. It implements the transfer function VO = VY(VZ/VX)^m, enabling precision multiplication, division, and exponentiation. The device features a wide dynamic range of 1000:1 in the denominator and requires no external trims, thanks to laser wafer trimming.
Key electrical specifications include a typical bandwidth of 400 kHz, maximum input offset voltage of 100 µV, and typical accuracy of ±0.25% of reading on a 100:1 range. It operates from dual supplies ranging from ±4.5 V to ±18 V, with a typical supply current of 7 mA. An on-board +2 V or +10 V scaling reference is provided.
The AD538BD is packaged in an 18-lead CDIP (Ceramic Dual In-line Package) with through-hole mounting. It is rated for an operating temperature range of -55°C to +125°C, making it suitable for harsh environments. The device is not RoHS compliant according to the manufacturer.
Typical applications include one- or two-quadrant multiply/divide, log ratio computation, squaring/square rooting, trigonometric function approximations, linearization via curve fitting, precision AGC, and power functions.
The AD538BD operates from dual supplies of ±4.5 V to ±18 V, with a typical supply of ±15 V.
