X9315Z

The Xicor X9315Z is a solid state "micropower" nonvolatile potentiometer and is ideal for digitally controlled resistance trimming. The features of X9315Z can be summarized as (1)Low Power CMOS: VCC = 2.7V to 5.5V,Single Supply, Active Current,50A (Increment) max,Active Current,400A (Store) Max, Standby Current,1A Max; (2)Low Noise; (3)31 Resistive Elements: Temperature Compensated,±20% End to End Resistance Range,VSS to VCC Range; (4)32 Wiper Tap Points: Wiper Positioned via Three-Wire Interface: Wimilar to TTL Up/Down Counter, Wiper Position Stored in Nonvolatile Memory and Recalled on Power-Up; (5)100 Year Wiper Position Data Retention: 1K; (6)Packages: 8-Lead SOIC,8-Lead MSOP,8-Pin DIP.

The absolute maximum ratings of the X9315Z are: (1)Temperature under Bias:65°C to +135°C; (2)Storage Temperature:65°C to +150°C; (3)Voltage on CS, INC, U/DVH,VL and VCC with Respect to VSS:1V to +7V; (4)V = |VHVL|: 5V; (5)Lead Temperature: 300°C; (6)Wiper Current:±1mA.
