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 converters both in conversion time and accuracy, while retaining the benefits of voltage-to-frequency conversion, i.

, 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.
