TC7106 Datasheet

TC7106 3-1/2 Digit Analog-to-Digital Converters

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 digi.

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 Ga.
