AD734ANZ

10 MHz, FourQuadrant Multiplier/Divider
GENERAL DESCRIPTION The AD734 is an accurate high speed, fourquadrant analog multiplier that is pin compatible with the industrystandard AD534 and provides the transfer function W = XY/U. The AD734 provides a low impedance voltage output with a full power (20 V pp) 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 buriedZener voltage reference. A new feature provides the option of substituting an external denominator voltage, allowing the use of the AD734 as a twoquadrant 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 gainbandwidth product of 200 MHz. FEATURES High accuracy 0.1% typical error High speed 10 MHz full power bandwidth 450 V/μs slew rate 200 ns settling to 0.1% at full power Low distortion −80 dBc from any input Thirdorder IMD typically −75 dBc at 10 MHz Low noise 94 dB SNR, 10 Hz to 20 kHz 70 dB SNR, 10 Hz to 10 MHz Direct division mode 2 MHz BW at gain of 100

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 gainbandwidth 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 14lead CERDIP and a 14lead PDIP package. The AD734SQ/883B, available processed to MILSTD883B for the military range of −55°C to +125°C, is available in a 14lead CERDIP.
