Dual, 256-Tap, Nonvolatile, SPI-Interface,  
Linear-Taper Digital Potentiometers  
General Description  
Features  
The MAX5487/MAX5488/MAX5489 dual, linear-taper,  
digital potentiometers function as mechanical poten-  
tiometers with a simple 3-wire SPI™-compatible digital  
interface that programs the wipers to any one of 256  
tap positions. These digital potentiometers feature a  
nonvolatile memory (EEPROM) to return the wipers to  
their previously stored positions upon power-up.  
♦ Wiper Position Stored in Nonvolatile Memory  
(EEPROM) and Recalled Upon Power-Up or  
Recalled by an Interface Command  
♦ 3mm x 3mm x 0.8mm, 16-Pin Thin QFN or 14-Pin  
TSSOP Packages  
♦
1 ꢀSꢁ INꢀ, 0.ꢂ ꢀSꢁ BNꢀ (ꢃoltage-Bivider Mode)  
The MAX5487 has an end-to-end resistance of 10kΩ,  
while the MAX5488 and MAX5489 have resistances of  
50kΩ and 100kΩ, respectively. These devices have a  
low 35ppm/°C end-to-end temperature coefficient, and  
operate from a single +2.7V to +5.25V supply.  
♦ 2ꢂ6 Tap Positions  
♦ 3ꢂppm/°C End-to-End Resistance Temperature  
Coefficient  
♦ ꢂppm/°C Ratiometric Temperature Coefficient  
The MAX5487/MAX5488/MAX5489 are available in  
16-pin 3mm x 3mm x 0.8mm thin QFN or 14-pin TSSOP  
packages. Each device is guaranteed over the extend-  
ed -40°C to +85°C temperature range.
