Description :

GENERAL DESCRIPTION

The AD734 is an accurate high speed, four-quadrant analog

multiplier that is pin compatible with the industry-standard

AD534 and provides the transfer function W = XY/U. The

AD734 provides a low impedance voltage output with a full

power (20 V p-p) bandwidth of 10 MHz. Total static error

(scaling, offsets, and nonlinearities combined) is 0.1% of full

scale. Distortion is typically less than −80 dBc and guaranteed.

The low capacitance X, Y, and Z inputs are fully differential.

In most applications, no external components are required to

define the function.

The internal scaling (denominator) voltage, U, is 10 V, derived

from a buried-Zener voltage reference. A new feature provides

the option of substituting an external denominator voltage,

allowing the use of the AD734 as a two-quadrant divider with a

1000:1 denominator range and a signal bandwidth that remains

10 MHz to a gain of 20 dB, 2 MHz at a gain of 40 dB, and 200 kHz

at a gain of 60 dB, for a gain-bandwidth product of 200 MHz.

The advanced performance of the AD734 is achieved by a

combination of new circuit techniques, the use of a high speed

complementary bipolar process, and a novel approach to laser

trimming based on ac signals rather than the customary dc

methods. The wide bandwidth (>40 MHz) of the AD734’s input

stages and the 200 MHz gain-bandwidth product of the multiplier

core allow the AD734 to be used as a low distortion demodulator

with input frequencies as high as 40 MHz as long as the desired

output frequency is less than 10 MHz.

The AD734AQ and AD734BQ are specified for the industrial

temperature range of −40°C to +85°C and come in a 14-lead

CERDIP and a 14-lead PDIP package. The AD734SQ/883B,

available processed to MIL-STD-883B for the military range of

−55°C to +125°C, is available in a 14-lead CERDIP.
