The AD532KDZ is a high-precision monolithic four-quadrant analog multiplier/divider with built-in trimming, widely used in analog computing, signal processing, instrumentation and industrial control applications.
The AD532KDZ is an internally trimmed, monolithic integrated circuit multiplier/divider manufactured by Analog Devices. This pre-trimmed single-chip device eliminates the need for external trimming resistors or an output operational amplifier, guaranteeing a maximum multiplication error of ±1.0% and a ±10V output range.
Transfer function: VOUT = (X1 - X2)(Y1 - Y2) / 10V
Accepts differential inputs for X and Y, providing high CMRR (75 dB).
Transfer function: VOUT = 10V · Z / (X1 - X2)
Squaring: VOUT = (X1 - X2)2 / 10V
Square root: VOUT = ±√(10V · Z) (single-quadrant)
- Pre-trimmed accuracy: ±1.0% max 4-quadrant error (AD532K grade)
- No external components required for calibration
- Differential inputs for noise rejection and flexible signal conditioning
- Monolithic construction: Compact, reliable, and cost-effective
- Direct replacement for older multipliers (e.g., AD530) needing external trims
- Analog computation: Multiplication, division, squaring, square-rooting
- Signal processing: Modulation, demodulation, and function generation
- Instrumentation: Transducer signal conditioning and sensor linearization
- Power measurement: Real-time calculation of V*I for power monitoring
- Control systems: Analog feedback loops and nonlinear compensation
