DESCRIPTION:
The CS454000 Programmable Light-to-Frequency Converter
combines a configurable silicon photodiode and a
current-to-frequency converter on single monolithic CMOS
integrated circuits. The output can be either a pulse train
or a square wave (50% duty cycle) with frequency directly
proportional to light intensity. Device sensitivity is
selectable in three ranges, providing two decades of
adjustment. The full-scale output frequency can be scaled by
one of four preset values. An output enable (OE) is provided
that places the output in the high-impedance state for
multiple-unit sharing of a C StampTM
microcontroller input line. The devices have an
absolute-output-frequency tolerances of ±20%. They have been
temperature compensated for the ultraviolet-to-visible light
range of 320 nm to 700 nm and respond over the light range
of 320 nm to 1050 nm. The devices are characterized over the
temperature range of −25°C to 70°C. All inputs and the
output are compatible with the C Stamp microcomputer’s
supplies and signal levels, allowing direct two-way
communication with the microcontroller for programming and
output interface. Communicating with the device is made easy
with A-WIT's supplied software commands STPIND and PULSIN.
This simple two commands interface is all that is required
to setup the device, and acquire frequency readings from it.
All items are new, fully
tested, factory direct!
All software included at no
extra charge!
