Q67007-A9335 Datasheet 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 preci- sion reference with a 20ppm/IC max temperature coeffi- cient. This represents a 4 t0 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 l 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 10121 input impedance. The differential reference input allows ratiometric measurements for ohms or bridge transducer measurements. The 15ccVP_P noise performance guarantees a "rock solid" read- ing. The auto-zero cycle guarantees a zero display read- ing with a zero-volts input. Q67007-A9335 Price 32 segment drivers ..
