AD5245BRJZ100-R2, Энергозависимый цифровой потенциометр, 100 кОм, Одиночный, 2-проводной, I2C, Последовательный

Полупроводники - Микросхемы\Цифровые Потенциометры\Энергозависимые Цифровые Потенциометры AD5245 is a 256-position I²C-compatible digital potentiometer. This potentiometer perform the same electronic adjustment function as mechanical potentiometers or variable resistors, with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance. The wiper settings are controllable through an I²C-compatible digital interface, which can also be used to read back the wiper register content. AD0 can be used to place two devices on the same bus. Command bits are available to reset the wiper position to midscale or to shut down the device into a state of zero power consumption. It is widely used in application such as mechanical potentiometer replacement in new designs, LCD panel VCOM adjustment, LCD panel brightness and contrast control, transducer adjustment of pressure, temperature, position, chemical, and optical sensors, RF amplifier biasing, automotive electronics adjustment, gain control and offset adjustment etc. • Fast settling time is tS = 5µs typ on power-up • Power-on preset to midscale, end-to-end resistance is 100Kohm • Computer software replaces microcontroller in factory programming applications • Single supply voltage range is 2.7V to 5.5V • Low temperature coefficient is 45ppm/°C • Low power IDD is 8µA maximum, bandwidth -3dB is 40kHz at RAB = 100Kohm, code = midscale • Resistor noise voltage density is 9nV/√Hz at (RWB = 5Kohm, RS = 0) • Total harmonic distortion is 0.1% at (VA = 1Vrms, VB = 0V, f = 1kHz, RAB = 10Kohm) • Operating temperature range is -40°C to +125°C • Packaging style is 8-lead SOT-23
