Voltage-to-Frequency Converter Features - 0.1 Hz to 250 k Hz dynamic range - 0.01% F.S. maximum nonlinearity error- 0.1Hz to 10 k Hz - 50 ppm/°C maximum gain temperature coefficient (external reference) - Few external ponents required Applications - - - - - - - - - - Precision voltage-to-frequency converters Serial transmission of analog information Pulse width modulators Frequency-to-voltage converters A/D converters and long term integrators Signal isolation FSK modulation/demodulation Frequency scaling Motor speed controls Phase lock loop stabilization Description The 4153 sets a new standard for ease of application and high frequency performance in monolithic voltage-tofrequency converters. This voltage-to-frequency converter requires only four passive external ponents 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 parable to many dual slop A/D converters 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. ..net PRODUCT SPECIFICATION Pin Assignments 4153 -VS 1 Gnd 2 2 VREF 3 VOUT 4 I IN 5 CO 6 Trig 7 IREF VREF 7.3V 14 VOS1 13 VOS2 12 -In 11 +In 10 +VS 9 FOUT Pin Descriptions Pin 1 2 3 4 5 6 7 8 9 10 11 12 13 14 -VS REF Gnd VREF Output VOUT (Op Amp) IIN (REF Input) CO (Pulse Width) Trigger Input Circuit Gnd Frequency Output (Open Collector) +VS (+) Op Amp Input (-) Op Amp Input VOS Trim VOS Trim Function One Shot 8 Gnd...
