Internally Trimmed Precision IC Multiplier (AD 534)

• The AD 534 isamonolithic laser trimmed four quadrant multiplier divider. No external trimming is required.

• AD 534 providesavery high accuracy.Amaximum multiplication error of 0.25%is guaranteed without external trimming

• It has very good supply rejection, low temperature coefficient and good Tong term stability

• It provides a fully differential, high impedance oneration on all innuts (including Z-inputs). This improve the flexibility and ease of operatic

• The scale factor has been pre adjusted to the standard value of 10.00 V, however it is possible to reduce it with the help of an external resistance toa value as low as 3V

• The AD 534 is the first general purpose multiplier that is capable of providing voltage gains uptox100. So in many applications as external instrumentation amplifier is not needed

• AD 534 can be used as a variable gain, differential input amplifier withahigh CMRR

• This multiplier is extremely flexible due to precise calibration and differential Z-input
