DESCRIPTION
The VFC101 voltage-to-frequency converter uses the
proven charge-balance technique with internal digital
logic to control the critical reference integration pe-
riod. Reference timing is derived from an external
clock signal which accurately sets the full-scale fre-
quency. This technique eliminates the errors and drift
from external timing components which are required
with other VFCs.
Internal resistors provide accurate full-scale input
ranges of 5V, 8V or 10V inputs without external
resistors or trimming. An accurate 5V reference volt-
age output is useful for bridge or sensor excitation.
With simple pin interconnections, it can provide half-
scale offset to allow bipolar input voltages.
The open-collector frequency output interfaces easily
to CMOS or TTL circuitry. Output one-shot circuitry
may be used to optimize the output pulse width for
optical couplers or transformers.
The VFC101 is packaged in a surface-mount 20-pin
PLCC (plastic leaded chip carrier) package.
