MAX5527/MAX5528/MAX5529 19-3665 Rev 1 7/09 One-Time Programmable, Linear-Taper Digital Potentiometers General Description Features Wiper Position Stored After One-Time Fuse The MAX5527/MAX5528/MAX5529 linear-taper digital Programming potentiometers perform the same function as mechanical potentiometers, replacing the mechanics with a simple 64 Tap Positions 2-wire up/down digital interface. These digital poten- Wiper Position Programmed Through Simple tiometers provide an optional one-time programmable 2-Wire Up/Down Interface feature that sets the power-on reset position of the wiper. 35ppm/C End-to-End Temperature Coefficient Once the wiper position is programmed, the 2-wire inter- face can be disabled to prevent unwanted adjustment. 5ppm/C Ratiometric Temperature Coefficient Ultra-Low 1.5A (max) Static Supply Current The MAX5527/MAX5528/MAX5529 provide an end-to-end resistance of 100k , 50k , and 10k , respectively. The +2.7V to +5.5V Single-Supply Operation devices feature low temperature coefficients of 35ppm/C 10k, 50k, and 100k End-to-End Resistances end-to-end and 5ppm/C ratiometric. All devices offer 64 Tiny, 3mm x 3mm, 8-Pin TDFN and 5mm x 3mm, wiper positions and operate from a single +2.7V to +5.5V 8-Pin MAX Packages supply. An ultra-low, 0.25A (typ) standby supply current saves power in battery-operated applications. Ordering Information The MAX5527/MAX5528/MAX5529 are available in 3mm x 3mm, 8-pin TDFN and 5mm x 3mm, 8-pin RESISTANCE TOP PART PIN-PACKAGE MAX packages. Each device is guaranteed over the (k ) MARK -40C to +105C temperature range.
