TC7107ACPL by Microchip Technology

3-1/2 Digit A/D, w/ LED Driver
Features
Internal Reference with Low Temperature Drift
20ppm/u00b0C Typical
Drives LED Display Directly
Guaranteed 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
High Impedance CMOS Differential Inputs: 1012 Ohm
Differential Reference Inputs Simplify Ratiometric Measurements
Low Power Operation: 10mW
Description
The TC7107A 3½ digit LED direct-display drive analog-to-digital converters allow existing TC7107 based systems to be upgraded. Each device has a precision reference with a 20ppm/°C max temperature coefficient. This represents a 4 to 7 times improvement over similar 3½ digit converters. Existing TC7107 based systems may be upgraded without changing external passive component values. The TC7107A drives common anode light emitting diode (LED) displays directly with 8mA per segment. A low-cost, high-resolution indicating meter requires only a display, four resistors, and four capacitors. The 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 1pA leakage current and a 1012 Ohm input impedance. The differential reference input allows ratiometric measurements for ohms or bridge transducer measurements. The 15µVp-p noise performance guarantees a great reading. The auto-zero cycle guarantees a zero display reading with a zero-volts input.

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 por- table 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 1012 Ω input impedance. The differential reference input allows ratiometric measurements for ohms or bridge transducer measurements. The 15 µVP–P noise performance ensures a “rock solid” reading. The auto- zero cycle ensures a zero display reading with a zero volts input. 3-1/2 Digit Analog-to-Digital Converters
