Produktbeschreibung
AD5247BKSZ100-1RL7 is a 128-position I²C-compatible digital potentiometer. This device performs the same electronic adjustment function as a mechanical potentiometer or a variable resistor. The wiper settings are controllable through the I²C-compatible digital interface, which can also be used to read back the present wiper register control word. The resistance between the wiper and either end point of the fixed resistor varies linearly with respect to the digital code transferred into the RDAC latch. Note the terms digital potentiometer, VR (variable resistor), and RDAC are used interchangeably in this document. It is used in applications such as mechanical potentiometer replacement in new designs, transducer adjustment of pressure, temperature, position, chemical, and optical sensors, RF amplifier-biasing, LCD brightness and contrast adjustment, automotive electronics adjustment, gain control and offset adjustment.
- I²C-compatible interface, full read/write of wiper register, 100Kohm RAB
- Power-on preset to midscale, single-supply voltage range from 2.7V to 5.5V
- Rheostat mode temperature coefficient is 45ppm/°C typ at (VDD = 5V ± 10% or 3V ± 10%)
- Differential nonlinearity is ±0.1LSB typical at (VDD = 5V ± 10% or 3V ± 10%)
- Integral nonlinearity is ±0.2LSB typical at (VDD = 5V ± 10% or 3V ± 10%)
- Supply current is 3μA typical at (IDD VDD = 5.5V; VIH = VDD or VIL = GND)
- 1.2MHz typical -3dB bandwidth at (RAB = 5Kohm, code = 0x40)
- Total harmonic distortion is 0.05% typical at (VA = 1V rms, VB = 0V, f = 1KHz)
- Resistor noise voltage density is 6nV/√Hz typical at (eN-WB RWB = 2.5Kohm, RS = 0 ohm)
- Operating temperature range from -40°C to +125°C, 6-lead SC70 package
