The TC7107 is a high-performance analog-to-digital converter (ADC) designed for digital voltmeter applications. It is capable of displaying voltage readings in a 3-digit format, utilizing either common cathode or common anode configurations to control the display segments effectively.
The device operates by multiplexing the output signals to drive a 3-digit display, allowing for efficient use of the display resources while minimizing power consumption. The thumb switch integrated into the design serves as a user interface for selecting between BCD (Binary-Coded Decimal) and hexadecimal output modes. This feature enhances the versatility of the voltmeter, making it suitable for various applications in electronic measurement.
In terms of circuit design, the TC7107 requires a reference voltage for accurate measurements, typically derived from a stable power supply. The display is driven by a series of transistors or driver ICs that are controlled by the multiplexing logic of the TC7107. The common pin configuration simplifies the wiring and reduces the number of required connections, facilitating easier assembly and maintenance.
The overall design should also include appropriate filtering capacitors to stabilize the power supply and minimize noise in the readings. Additionally, protection diodes may be included to safeguard the circuit against reverse polarity and overvoltage conditions, ensuring the longevity and reliability of the voltmeter.hi here is new models 3 digit cc and ca dispaly multiplexed 3 didgit voltmeter chip TC7107(ICL7107) Thumb switch with commom pin bcd and hex regards.. 🔗 External reference
