Special-purpose Analog-to-Digital Converters (ADCs) perform dedicated functions such as dual-slope conversion, voltage-to-frequency conversion, frequency-to-voltage conversion and 3½ digit Binary-Coded Decimal (BCD) and binary conversion. These devices may be combined with other functions such as driving Liquid Crystal Displays (LCDs) or Light Emitting Diodes (LEDs).
