TC7126 General Description
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 ntegrated 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. 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 1012Ω input impedance.The 15µVP-P noise performance ensures a "rock solid" reading,and the auto-zero cycle ensures a zero display reading with a 0V input.
