Product Overview
AD5122ABRUZ100 is a dual channel, 128-position, I²C, non-volatile digital potentiometer. It offers guaranteed low resistor tolerance errors of ±8% and upto ±6mA current density in the Ax, Bx, and Wx pins. The low resistor tolerance and low nominal temperature coefficient simplify open-loop applications as well as applications requiring tolerance matching. The linear gain setting mode allows independent programming of the resistance between the digital potentiometer terminals, through RAW and RWB the string resistors, allowing very accurate resistor matching. The high bandwidth and low total harmonic distortion (THD) ensure optimal performance for AC signals, making it suitable for filter design. It is used in applications such as portable electronics level adjustment, LCD panel brightness and contrast controls, programmable filters, delays, and time constants, and programmable power supplies.
- Linear gain setting mode, single- and dual-supply operation
- Resistor integral nonlinearity is ±0.1LSB typ at (VDD = 2.3V to 5.5V, VSS = 0V)
- Resistor differential nonlinearity is ±0.1LSB typ at (VDD = 2.3V to 5.5V, VSS = 0V)
- Resistance temperature coefficient is 35ppm/°C typical at (code = full scale, VDD = 2.3V to 5.5V)
- 0.43MHz typical -3dB bandwidth at (RAB = 100Kohm, VDD = 2.3V to 5.5V, VSS = 0V)
- VW settling time is 12µs typical at (RAB = 100Kohm, VDD = 2.3V to 5.5V, VSS = 0V)
- Resistor noise density is 20nV/√Hz typical at (RAB = 100Kohm, VDD = 2.3V to 5.5V, VSS = 0V)
- Power supply rejection ratio is -66dB typical at (∆VDD/∆VSS = VDD ±10%, code = full scale)
- Logic supply voltage range from 1.8V to 5.5V, power dissipation is 3.5µW typical
- Operating temperature range from -40°C to +125°C, 16-lead TSSOP package
