It can be used in instrumentation, industrial, and automation markets. This pin is routed to the mikroBUS™ CS pin and it is labeled as EN. This will activate the boost converter and provide the required power for the VFC32KU IC. To enable the conversion circuitry, the EN pin of the TPS65131 boost converter should be pulled to a HIGH logic level. Providing well-stabilized output with the plenty of power headroom, it is a perfect solution for the HZ to V 2 click, also. This DC/DC converter has already been used in Boost-INV 2 click, so it was tested 'on the field' for this purpose. It uses the TPS65131, a positive and negative output DC/DC Converter IC, also from Texas Instruments.

Therefore, this Click board™ utilizes another IC in order to provide the required voltages. The VFC32KU IC requires a dual power supply with ☑5V. It is recommended to correct the offset after longer time intervals, to compensate for the aging of the passive components on the Click board™. An offset trimming procedure should be executed before the first use of the Click board™, since even slight variations in the components tolerances could affect the value at the output. It can be calibrated by using the offset potentiometer, by introducing a signal of a known frequency to either FEXT input terminal or the PWM input pin. A DC voltage output ranging up to 3.3V is available both on the AN pin of the mikroBUS™ labeled as the VO, and the output terminal - labeled as the VOUT on this Click board™.Īn onboard high-precision OFFSET potentiometer is used to fine-tune the output of the Click board™. The signal input source can be selected by the onboard switch, labeled as INPUT SEL. This signal is AC coupled by a 1nF capacitor, meaning that no DC component will be affecting the connected source. The input signal within the specified frequency range can be applied to either the PWM pin of the mikroBUS™ labeled as FIN on this Click board™ or to the external signal input terminal labeled as FEXT. This makes the DC voltage output suitable for sampling, or further processing by the host MCU. The output DC voltage level is further scaled down by the voltage divider on the VFC32KU output, in order to achieve levels acceptable by the MCU. It accepts a signal with the frequency within a range between 200Hz and 120kHz on the input and generates DC voltage with the level corresponding to the input frequency, ranging from 0V to 10V, with a highly linear response. The main component of Hz to V 2 click is the VFC32KU, a voltage-to-frequency and frequency-to-voltage converter from Texas Instruments. This can be utilized to build an FM modulator/demodulator application, for example. Its function can be complemented by the V to Hz 2 click, which does the opposite type of conversion: DC voltage to frequency. It is well suited for use in A/D conversion, long-term integration, frequency to voltage conversion, RPM measurement, capacitance measurement, and similar applications which can benefit from an accurate and reliable frequency to voltage conversion. We've purchased the product and are waiting for it to arrive in our lab.These features allow HZ to V 2 click to be used in various frequency to voltage applications: in instrumentation, industrial, and automation markets. The product has arrived in our lab, and our testers will start evaluating it soon. Our testers have started testing this product. Measured the response times with a new overdrive setting.įixed an error about the built-in speakers. Added tests for Console Compatibility and macOS compatibility and made minor changes to other tests, which you can see in our Changelog. Updated to Test Bench 1.2, resulting in changes to the results and scores with the Response Time and Input Lag. We tested the monitor with the PS5's new variable refresh rate feature and confirmed that it's not compatible, since the PS5 only supports HDMI Forum VRR. Tested the monitor's compatibility with 1440p on the PS5, but it doesn't work. Fixed the BFI Input Lag result to match the input lag at the max refresh rate.Ĭorrected an error with the Input Lag measurement at the max refresh rate.Ĭlarified that the Input Lag is low at high refresh rates, but starts to increase at 85Hz and below.
