CA3162A中文资料A/D Converters for 3-Digit Display数据手册Renesas规格书

描述 Description

The CA3162E and CA3162AE are I2L monolithic A/D converters that provide a 3 digit multiplexed BCD output. They are used with the CA3161E BCD-to-Seven-Segment Decoder/Driver and a minimum of external parts to implement a complete 3-digit display. The CA3162AE is identical
to the CA3162E except for an extended operating temperature range.
