MAX5394LATA+T by Analog Devices

Single, 256-Tap Volatile, SPI, Low-Voltage Linear Taper Digital Potentiometer


The MAX5394 single, 256-tap volatile, low-voltage linear taper digital potentiometer offers three end-to-end resistance values of 10kΩ, 50kΩ, and 100kΩ. Potentiometer terminals are independent of supply for voltages up to 5.25V with single-supply operation from 1.7V to 5.5V (charge pump enabled). User-controlled shutdown modes allow the H, W, or L terminal to be opened with the wiper position set to zero-code, midcode, full-code, or the value contained in the wiper register. Ultralow-quiescent supply current (< 1µA) can be achieved for supply voltages between 2.6V and 5.5V by disabling the internal charge pump and not allowing potentiometer terminals to exceed the supply voltage by more than 0.3V. The MAX5394 provides a low 50ppm/°C end-to-end temperature coefficient and features a SPI serial interface. The small package size, low operating supply voltage, low supply current, and automotive temperature range of the MAX5394 make the device uniquely suited for the portable consumer market and battery-backup industrial applications. The MAX5394 is available in a lead-free, 8-pin TDFN (2mm x 2mm) package. The device operates over the -40°C to +125°C automotive temperature range.
