Product Summary

The DS1669 DallastatTM is a digital rheostat or potentiometer. This device supports 64 possible uniformtap points over the entire resistive range. The standard resistive ranges are 10 kΩ, 50 kΩ, and 100 kΩ.The Dallastat can be controlled by either a switch contact closure input or a digital source input such as a CPU. Wiper position is maintained in the absence of power through the use of a EEPROM memory cellarray. The EEPROM cell array will withstand more than 50,000 writes.

Parametrics

The absolute maximum ratings of DS1669-10 are (1)Voltage on Any Pin Relative to -V:-V -0.5V + 8.0V; (2)Operating Temperature:-40°C to +85°C; (3)Storage Temperature:-55°C to +125°C; (4)Soldering Temperature:260°C for 15 seconds

Features
