Product Summary
The C7135 is a converter with Texas Instruments highly efficient CMOS technology. These 4 1/2-digit, dual-slope-integrating, analog-to-digital converters (DACs) are designed to provide interfaces to both a microprocessor and a visual display. The digit-drive outputs D1 through D4 and multiplexed binary-coded-decimal outputs B1, B2, B4, and B8 provide an interface for LED or LCD decoder/drivers as well as microprocessors.
Parametrics
C7135 absolute maximum ratings: (1)supply voltage (vcc+ with respect to vcc–): 15 v; (2)analog input voltage (in– or in+: vcc– to vcc+; (3)reference voltage range: vcc– to vcc+; (4)clock input voltage range: 0 v to vcc+; (5)operating free-air temperature range, ta: 0°c to 70°c; (6)storage temperature range, tstg: –65°c to 150°c; (7)lead temperature 1,6 mm (1/16 inch)from case for 10 seconds: n package: 260°c.
Features
C7135 features: (1)zero reading for 0-v input; (2)precision null detection with true polarity at zero; (3)1-pa typical input current; (4)true differential input; (5)multiplexed binary-coded-decimal (bcd)output; (6)low rollover error: ±1 count max; (7)control signals allow interfacing with uarts or microprocessors; (8)autoranging capability with over-and under-range signals; (9)ttl-compatible outputs; (10)direct replacement for teledyne tsc7135, intersil icl7135, maxim icl7135, and siliconix si7135; (11)cmos technology.
