NTE2055 Integrated Circuit
CMOS, 3 1/2 Digit A/D Converter
Description: The NTE2055 is a high performance, low power, 3 1/2 digit A/D converter combining both linear
CMOS and digital
CMOS circuits on a single monolithic IC. Available in a 24–Lead DIP type package, this device is designed to minimize use of external components. With two external resistors and two external
capacitors, the system forms a dual slope A/D converter with automatic zero correction and automatic polarity. The NTE2055 is ratiometric and may be used over a full–scale range from 1.999V to 199.9mV. Systems using this device may operate over a wide range of power supply
voltages for ease of use with batteries, or with standard 5V supplies. The output drive conforms with standard B–Series
CMOS specifications and can drive a low–power Schottky TTL load. The high impedance MOS inputs allow applications in current and resistance meters as well as voltmeters. In addition to DVM/DPM applications, the NTE2055 finds use in digital thermometers, digital scales, remote A/D, A/D control systems, and in MPU systems.
