The AD652KP is a monolithic integrated circuit that provides three functions in one package. It is a precision Programmable Voltage-to-Frequency Converter, a precision Frequency-to-Voltage Converter, and a Voltage-on-Delay Circuit. It is suitable for applications such as portable or embedded controller systems that use pulse frequency or pulse width modulation techniques for digital controls or data conversion. The device contains high accuracy Voltage-to-Frequency and Frequency-to-Voltage converters with easily programmable frequency models via a single software-controlled programmable comparator reference. It also contains a built-in high accuracy precision Voltage-on-Delay circuit.
The Programmable Voltage-to-Frequency Converter (VFC) is designed to be controlled directly by an external analog voltage. It features a linear conversion of input voltage to output frequency. The voltage-frequency efficiency of operation is adjustable via the reference control, hence the frequency range of output can be tailored to the required application. As such, the output frequency can be modulated as a function of the external input voltage. A voltage bypass set by the reference control helps reduce errors due to noise on the input line.
The Frequency-to-Voltage Converter (FVC) is designed to be controlled by an external frequency source. It features an accurate sampled-data frequency to voltage ratios easily adjustable via the reference control. This allows it to accurately track the input frequency and convert it to an output voltage for further data acquisition and processing. The Linearity of this feature is quoted as ±0.3%. Further accuracy improvement may be obtained using external gain buffers.
Also included in the package is the Voltage-on-Delay circuit. This feature is designed to provide a voltage trigger at a programmable delayed time after the input voltage reaches its Trip Point Voltage (TPV). The amount of delay time is programmable via the reference control. It is adjustable in a range between a few milliseconds up to several seconds.
The AD652KP is a monolithic integrated circuit suitable for use in applications such as voltage/frequency monitoring, data acquisition, and digital controllers. The low power operation and precision internal control logic make it especially suitable for battery powered and portable applications. The tiny 6-lead SOT23 package helps to minimize the PCB area required and its miniature size facilitates system miniaturization.
