The RC4153 has the following features including 0.1 Hz to 250 kHz dynamic range;0.01% F.S. maximum nonlinearity error-O.1Hz to 10 kHz;50 ppm/0C maximum gain temperature coefficient(external reference);Few external components required.
The RC4153 sell 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 frcqucncy makcs it comparablc to many dual slop A/D converlers both in conversion lime 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."Absolute maximum ratings" are those beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the RC4153 should be operated at these limits. If the device is subjected to the limits in the absolute maximum ratings for extended periods, its reliability may be impaired. The tables of Electrical Characteristics provide conditions for actual device operation.
Once your system is running, RC4153 may be calibrated as follows:apply a mcasurcd full scalc input voltagc and adjust RAN until the scale factor is correct. For precise applications, trimming by soldering metal film resistors in parallel is recommended instcad of trimpots, which havc bad tcmpco's and arc casily taken out of adjustment by mechanical shock. After the scale factor is calibrated, apply a known small input voltage(approximatcly 10 mV) and adjust the op amp offsct until the output frequency equals the input multiplied by the scale Factor.Capacitive coupling between the trigger input and the timing capacitor pin may occur if the input waveform is a square-wave or the input has a short period. This can cause gross nonlinearity due to changes in the one-shot timing waveform (See Figure 7). This problem can be avoided by keeping the value of Cp small, and thereby keeping the timing period less than the input waveform period.
