Voltage Divider
Voltage dividers are used to step down voltages for analog
processing. Applications are found in multi-meters, oscillo-
scopes, oscillator stage of voltage control oscillators, etc. The
application needs precise resistors to ensure that errors are not
added during the conversion process.

Data Conversion
Data converters are used to convert digital data to analog sig-
nals or vice versa. The precision of the high bit affects the over-
all precision of the data convertor. Thus, thick film resistors are
used in the lower bits while the thin film or bulk foil resistors are
used in the high order bits.
