The TC7126A is a 3-1/2 digit CMOS analog-to-digital converter (ADC)containing all the active components necessary to construct a 0.05%resolution measurement system.Seven-segment decoders,digit and polarity drivers, voltage reference,and clock circuit are integrated on-chip. The TC7126A directly drives a liquid crystal display (LCD), and includes a backplane driver. A low-cost,high-resolution indicating meter requires only a display,four resistors,and four capacitors. The TC7126A's extremely low power drain and 9V battery operation make it ideal for portable applications. The TC7126A reduces linearity error to less than 1 count.Roll-over 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 10 12 ? input impedance.The 15 VP-P noise performance guarantees a "rock solid"reading,and the auto-zero cycle guarantees a zero display reading with a 0V input. The TC7126A features a precision, low-drift internal voltage reference an disfunctionally identical to the TC7126. A low-drift external reference is not normally required with the TC7126A.
