AD539: Wideband Dual-Channel Linear Multiplier/Divider

The AD539 is a low-distortion analog multiplier having two identical signal channels (Y1 and Y2), with a common X-input providing linear control of gain. Excellent ac characteristics up to video frequencies and a 3dB bandwidth of over 60MHz are provided. Although intended primarily for applications where speed is importanct the circuit exhibits good static accuracy in "computational" applications. Scaling is accurately determined by a band-gap voltage reference and all critical parameters are laser-trimmed during manufacture.

The full bandwidth can be realized over most of the gain range using the AD539 with simple resistive loads of up to 100 (Ohms). Output voltage is restricted to a few hundred millivolts under these conditions. Using external op amps such as the AD5539 in conjuction with the on-chip scaling resistors, accurate multiplication can be achieved, with bandwidths typically as high as 50 MHz.

The two channels provide flexibility. In single-channel applications they may be used in parallel, to double the output current, or series, to achieve a square law gain function with a control range or over 100dB, or differentially, to reduce distortion. Alternatively, they may be used independently, as in audio stereo applications, with low crosstalk between channels. Voltage controlled filters and oscillators using the "state-variable" approach are easily designed, taking advantage of the dual channels and common control. The AD539 is available in three versions: the "J" and "K" grades are specified for 0 to +70°C operation and "S" grade is guaranteed over the extended range of -55°C to +125°C. The J and K grades are available in either a hermetic ceramic DIP (D) or a low cost plastic DIP (N), while the S grade is available in ceramic DIP (D) or LCC (E). J-grade chips are also available. The S grade is now available in MIL-STD-883 and Standard Military Drawing (DESC) Number 5962-8980901EA versions.
