TC7106/A/TC7107/A
3-1/2 Digit Analog-to-Digital Converters
Features: General Description: Internal Reference with Low Temperature Drift:
-TC7106/TC7107: 80 ppm/В°C (Typical)
-TC7106A/TC7107A: 20 ppm/В°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: 1012О© Differential Reference Inputs Simplify Ratiometric
Measurements Low-Power Operation: 10 mW 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/В°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. Applications: Thermometry Bridge Readouts: Strain Gauges, Load Cells, Null
Detectors Digital Meters: Voltage/Current/Ohms/Power, pH Digital Scales, Process Monitors Portable Instrumentation В© 2008 Microchip Technology Inc. The TC7106A/TC7107A reduces linearity error to less …
