ADI JM38510/13903BIA

The AD534 is a monolithic laser-trimmed four-quadrant multiplier/divider with accuracy specifications previously found only in expensive hybrid or modular products. For the AD534L, the guaranteed maximum multiplication error is ±0.25% with no external trimming required. Excellent power supply rejection, low temperature coefficient, and the long-term stability of on-chip thin-film resistors and buried zener reference maintain accuracy even under adverse operating conditions. It is the first multiplier to offer fully differential high-impedance operation on all inputs, including the Z input — a feature that greatly increases flexibility and ease of use. The scale factor is pretrimmed to the standard value of 10.00V; it can be reduced to as low as 3V via an external resistor.

Specifications for the AD534J (maximum error ±1%), AD534K (maximum error ±0.5%), and AD534L (maximum error ±0.25%) apply over the 0°C to +70°C temperature range. The AD534S (maximum error ±1%) and AD534T (maximum error ±0.5%) are specified over the extended temperature range of −55°C to +125°C. All grades are available in hermetic TO-100 metal can and SBDIP packages. The AD534K, AD534S, and AD534T dice are also available.
