iC-BM FOUR-CHANNEL
FOUR-QUADRANT ANALOG MULTIPLIER
Rev A2, Page 2/7
DESCRIPTION
iC-BM features four analog multipliers. Each four-
quadrant multiplier consists of a Gilbert cell multiplier
with a 0.4 scale factor, a linearisation circuit and a
unity gain output amplifier.
For higher precision all internal bias currents are de-
rived from an internal band-gap reference.
All pins are ESD protected.
