Each device has a preci- sion reference with a 20ppm/ °C max temperature coeffi- cient. 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 pas- sive 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 1012 Ω input impedance. The differential reference input allows ratiometric measurements for ohms or bridge transducer measurements. The 15 µVP–P noise performance guarantees a “rock solid” read- ing. The auto-zero cycle guarantees a zero display read- ing with a zero-volts input.
