Overview
TC7106/A/TC7107/A 3-1/2 Digit Analog-to-Digital Converters Features: • Internal Reference with Low Temperature Drift: - TC7106/TC7107: 80 ppm/°C (Typical) - TC7106A/TC7107A: 20 ppm/°C (Typical) • Drives LCD (TC7106) or LED (TC7107) Display Directly • Zero Reading with Zero Input • Low Noise for Stable Display • Auto-Zero Cycle Eliminates Need for Zero Adjustment • True Polarity Indication for Precision Null Applications • Convenient 9V Battery Operation (TC7106A) • High-Impedance CMOS Differential Inputs: 1012Ω • Differential Reference Inputs Simplify Ratiometric Measurements • Low-Power Operation: 10 mW Applications: • Thermometry • Bridge Readouts: Strain Gauges, Load Cells, Null Detectors • Digital Meters: Voltage/Current/Ohms/Power, pH • Digital Scales, Process Monitors • Portable Instrumentation General Description: The TC7106A and TC7107A 3-1/2 digit direct display drive Analog-to-Digital Converters allow existing TC7106/TC7107 based systems to be upgraded.
Each device has a precision reference with a 20 ppm/°C maximum temperature coefficient.
This represents a 4 to 7 times improvement over similar 3-1/2 digit converters.
Existing TC7106 and TC7107 based systems may be upgraded without changing external passive component values.
The TC7107A drives common anode light emitting diode (LED) displays directly with 8 mA per segment.
A low cost, high resolution indicating meter requires only a display, four resistors, and four capacitors.
The TC7106A low-power drain and 9V battery operation make it suitable for portable applications.
The TC7106A/TC7107A reduces linearity error to less than 1 count.
Rollover error – the difference in readings for equal magnitude, but opposite polarity input signals, is below ±1 count.
High-impedance differential inputs offer 1 pA leakage current and a 1012Ω input impedance.
The differential reference input allows ratiometric measurements for ohms or bridge transducer measurements.
The 15 µVP–P noise performance ensures a “rock soli...
