描述 Description

Description:
The NTE2055 is a high performance, low power, 3 1/2digit 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.Features:
