AD5114BCPZ10-1-RL7 is a monolithic integrated high-precision digital potentiometer. It is designed for applications that require precise control of multiple adjustable resistance paths. This integrated device is a perfect combination of a digitally controlled operational amplifier and power transmitter and receiver, which can be used to provide constant current or voltage output signals to control resistances of different order.Data acquisition - digital potentiometers commonly use resistor divider networks (RDs) to control variable resistance. The RD network contains a variable resistor with an enabling resistor in series, and the connection of these two resistors controls the output resistance. The digital potentiometer replaces the variable resistor in the network, and its wiper position is controlled by a digital protocol, such as SPI or I2C.The AD5114BCPZ10-1-RL7 is a 4-bit digital potentiometer. It has a wiper resistance of 64 mΩ and a maximum resolution of 16 steps. The integrated device contains two separate power supplies, a 6.25 V logic supply and a 5 V supply, allowing the device to operate from two different power sources and achieve a wide direction of adjustment range. The AD5114BCPZ10-1-RL7 also provides a wide temperature range of –40°C to +85°C and an ultra-high temperature stability of 0.01%/°C. In addition, the AD5114BCPZ10-1-RL7 can provide a wide control range, exceeding the resolution of many standard digital potentiometers, making it a good choice for applications which require precise resistance control. The working principle of the AD5114BCPZ10-1-RL7 is based on voltage sensing. A 2-bit register, one determined by the voltage regulator, sets the wiper position, while another 2-bit register determines the end of range values, providing finer control. The output resistance is monitored by the comparator, and the digital potentiometer adjusts the output resistor or resistance network according to the signal level received from the two-bit register. This allows precise adjustment of the resistor divider output resistance. The AD5114BCPZ10-1-RL7 is great for applications requiring low current, precise adjustable resistance control. It can be used for wide range of applications such as setting the gain of amplifiers, adjusting reference levels in power supplies, controlling feedback loops in audio systems and voltage control in automotive applications. Its high-resolution control, wide temperature range, low power consumption and low noise performance make the AD5114BCPZ10-1-RL7 an excellent choice for many applications.
