CA3161 IC + CA3162 IC Pair A/D Converter for 3 Digit Display DIP-16 Package

The CA3161 is a monolithic integrated circuit that performs the BCD to seven segment decoding function and features constant current segment drivers. When used with the CA3162 A/D Converter the CA3161 provides a complete digital readout system with a minimum number of external parts. The CA3162 and CA3162 are I2L monolithic A/D converters that provide a 3 digit multiplexed BCD output. They are used with the CA3161 BCD-to-Seven-Segment Decoder/Driver and a minimum of external parts to implement a complete 3-digit display. The CA3162 is identical to the CA3162 except for an extended operating temperature range .
