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.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• Internal Timing – No External Clock Required• Choice of Low Speed (4Hz) or High Speed (96Hz) Conversion Rate• “Hold” Inhibits Conversion but Maintains Delay• Over range Indication – “EEE” for Reading Greater than 999mV, “-” for Reading More Negative than -99mV When Used With CA3161Specification of CA3161 IC:-ParametersSpecificationDC V SUPPLY 7.0 VInput Voltage 5.5 VOutput VoltageOutput “Off” 7 VOutput “On” 10 VSpecification of CA3162 IC:-ParametersSpecificationDC V SUPPLY 7.0 VInput Voltage 15 VTemperature Range0 to 75ca3161-ic-datasheetca3162-ic-datasheet* product image for illustration purposes only. actual product may vary.
