Description

The 4153 sets a new standard for ease of application and

high frequency performance in monolithic voltage-to-

frequency converters. This voltage-to-frequency converter

requires only four passive external components for precision

operation, making it ideal for many low cost applications

such as A/D conversion, frequency-to-voltage conversion,

and serial data transmission. The improved linearity at high

frequency makes it comparable to many dual slop A/D con-

verters both in conversion time and accuracy, while retaining

the benefits of voltage-to-frequency conversion, i.e., serial

output, cost and size. The speed accuracy and temperature

performance of the 4153 is achieved by incorporating high

speed ECL logic, a high gain, wide bandwidth op amp, and a

buried Zener reference on a single monolithic chip.
