Product Overview

The AD538BDZ is a real-time monolithic Analog Computational Unit (ACU) provides precision analogue multiplication, division and exponentiation. The combination of low input and output offset voltages and excellent linearity results in accurate computation over an unusually wide input dynamic range. Laser wafer trimming makes multiplication and division with errors as low as 0.25% of reading possible, while typical output offsets of 100μV or less add to the overall off-the-shelf performance level. Real-time analogue signal processing is further enhanced by the 400kHz bandwidth of the device. The overall transfer function of the AD538 is VO=VY (VZ/VX)m. Programming a particular function is via pin strapping. No external components are required for one-quadrant (positive input) multiplication and division. Two-quadrant (bipolar numerator) division is possible with the use of external level shifting and scaling resistors.
  • Simultaneous multiplication and division
  • Resistor-programmable powers and roots
  • No external trims required
  • Low error ±0.25% of reading (100:1 range)
  • Monolithic construction
  • Real-time analogue multiplication, division and exponentiation
  • High accuracy analogue division with a wide input dynamic range
  • On-board +2 or +10V scaling reference
  • Voltage and current (summing) input modes
  • Monolithic construction with lower cost and higher reliability than hybrid and modular circuits
  • 1000:1 Wide dynamic range (denominator)
  • <100μV Low input offsets
