The TC7106 3-1/2 digit direct display drive Analog-to-Digital Converters allow existing TC7106 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 based systems may be upgraded without changing external passive component values. The TC7106 low-power drain and 9V battery operation make it suitable for portable applications. The TC7106 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 1012O 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 autozero cycle ensures a zero display reading with a zero volts input.
