GENERAL DESCRIPTION
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 3 dB bandwidth of over 60 MHz are
provided. Although intended primarily for applications where
speed is important, 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 Ω.
Output voltage is restricted to a few hundred millivolts under
these conditions.
The two channels provide flexibility. In single-channel applications,
they can be used in parallel to double the output current, in
series to achieve a square-law gain function with a control range of
over 100 dB, or differentially to reduce distortion. Alternatively,
they can 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 can also be configured as a divider with
signal bandwidths up to 15 MHz.
Power consumption is only 135 mW using the recommended
±5 V supplies. 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 SBDIP (D-16)
or a low cost PDIP (N-16), whereas the S grade is available in
ceramic SBDIP (D-16) or LCC (E-20-1). The S grade is availa-
ble in MIL-STD-883 and Standard Military Drawing (DESC)
Number 5962-8980901EA versions.
