equal. Alternatively, an autocalibration circuit using two D/A
converters can be employed. This can also be used to calibrate
out the effects of offset voltage drift over temperature.
The switch choice, for U1s, is critical in this type of design. The
DG542 utilizes “T” switching techniques on each channel for
exceptionally low crosstalk and for high isolation. The part fur-

ther improves these specifications by using ground pins between
the signal pins. With an input frequency of 5 MHz, crosstalk
and isolation are –85 dB and –75 dB, respectively. A limitation
of this switch is that it operates from a maximum –5 V negative
supply, making bipolar operation more difficult. It is recom-
mended that amplifiers A1, A2 and A3 operate from the same
–5 V supply to minimize any potential latch-up problems.
