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.
Features of CA3161 IC:-
• TTL Compatible Input Logic Levels
• 25mA (Typ) Constant Current Segment Outputs
• Eliminates Need for Output Current Limiting Resistors
• Pin Compatible with Other Industry Standard Decoders
• Low Standby Power Dissipation . . . . . . . .18mW (Typ)
Features of CA3162 IC:-
• Dual Slope A/D Conversion
• Multiplexed BCD Display
• Ultra Stable Internal Band Gap Voltage Reference
• Capable of Reading 99mV Below Ground with Single Supply
• Differential Input
