Description
The THAT 1420 and 1430 are a new genera-

technology, a dual feedback-loop de-
To overcome this problem, the THAT 1420
and 1430 use two individual negative-feedback
loops to separately control the differential output
voltage and common mode output currents, mak-
ing the design inherently more stable and less
sensitive to component tolerances than the CCOS.
Most importantly, the dual-feedback design pre-
vents the loss of common-mode feedback that
plagues the CCOS designs, avoiding the excessive
ground
currents
and
waveform that can result when driving sin-

output
Where minimum output offset voltage with
minimum parts count is desired, the THAT 1430
further improves over existing designs.
ventional CCOS circuits, two relatively high-value
electrolytic capacitors are required to reduce the
offset voltage. By contrast, the THAT 1430 topol-
ogy requires only a resistor and a single film or
ceramic capacitor to achieve the same effect at
lower parts count and price.
