Description

The TC7106A and TC7107A 3-1/2 digit direct-display drive analog-to-digital converters allow existing 7106/7107 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 3-1/2 digit converters. Existing 7106 and 7107 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 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 1pA leakage current and a 10 12 Ω input impedance. The differential reference input allows ratiometric measurements for ohms or bridge transducer measurements. The 15VPP noise performance guarantees a "rock solid" reading. The auto-zero cycle guarantees a zero display reading with a zero-volts input.
