TLC7135CDW 

4.5-bit, 0.003kSPS ADC, hybrid BCD output, true differential input, single channel

illustrate   The ICL7135C and TLC7135C converter are made by Texas Instruments with high-efficiency CMOS technology. These 4 1/2-digit, dual-slope integrated, analog-to-digital converter (ADC) design interfaces provide both a microprocessor and a visual display. The digital driver outputs to D4 and multiplexed binary-encoded decimal outputs B1, B2, B4, D1 and B8 provide an LED or LCD decoder/driver and microprocessor interface. TLC7135C provides a ICL7135C and a resolution of 50 ppm (one in the 20,000 part), with a maximum linear error. Low input current (less than 10 Pa) with zero error of less than 10 μV and zero drift of less than 0.5 μV/°C source impedance error minimized.   characteristic   Zero reading is 0 - V input Precision detection and True polarity at zero point 1 - Typical input current for PA True differential input Multiplexed binary-encoded decimal (BCD) output Low flip error: ± 1 count maximum The control signal can be via the interface of the UART or microprocessor Automatic adjustment capability with overvoltage and main range signals TTL-compatible output The second source is Teledyne TSC7135, Intersil ICL7135, Maxim ICL7135, Si7135 and Siliconix CMOS technology
