CA3162 Dual Slope & Rate Analog/Digital Conv – Datasheet

The CA3162 is an I2L monolithic A/D converter that provides a 3 digit multiplexed BCD output. This is used with the CA3161E 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 CA3162AE except for an extended operating temperature range.
