Maxim Integrated provides a recommended PCB layout in the DS1851E datasheet, which includes guidelines for component placement, routing, and thermal management. Additionally, it's recommended to follow general high-frequency PCB design practices, such as using a solid ground plane, minimizing trace lengths, and avoiding vias under the device.
The DS1851E-010+T&R is a digitally controlled potentiometer, and its output voltage can be programmed using the I2C interface. The device has a 7-bit wiper register that controls the output voltage, and the desired output voltage can be achieved by writing the appropriate value to this register. The datasheet provides a detailed explanation of the wiper register and the calculation for determining the desired output voltage.
The DS1851E-010+T&R has a maximum current rating of 1mA per terminal. This means that the total current drawn from the device should not exceed 3mA (1mA per terminal x 3 terminals). Exceeding this current rating can lead to device damage or degradation.
The DS1851E-010+T&R requires a power supply voltage (VCC) between 2.7V and 5.5V, and a logic supply voltage (VL) between 1.8V and 5.5V. The device also requires a bypass capacitor between VCC and GND to filter out noise and ensure stable operation. Additionally, the datasheet recommends using a pull-up resistor on the SCL and SDA lines to ensure proper I2C communication.
The DS1851E-010+T&R has a typical response time of 10μs to a digital input change. This means that when the device receives a new digital input, it takes approximately 10μs to settle to the new output voltage. This response time can vary depending on the specific application and operating conditions.
