iC-OC
INTEGRATING LIGHT-VOLTAGE CONVERTER
Rev D1, Page 2/9
DESCRIPTION
iC-OC is an optical sensor with two photodiodes, two
integrating amplifiers and a control logic which en-
ables several iC-OCs to be connected in a chain.
Furthermore, the control logic, consisting of a two-
stage shift register, determines when the integration
time starts and ends and switches the integrators
in sequence to the analogue output. The analogue
output is a source follower and in its deactivated
state has a high impedance and can thus be used
in buses.
The control logic output supplies a CMOS compatible
signal and in chain connection it can be directly linked
to the digital input of the next device. Logic inputs are
configured as Schmitt triggers and are TTL/CMOS-
compatible.
All the registers in the device are reset with low
voltage (power-down reset). All pins are protected
against ESD.
