X9428WP-2.7

The X9428WP-2.7 is one member of the X9428 family which is designed as the single digitally controlled potentiometer that can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of applications including control, parameter adjustments, and signal processing. This device is implemented using 63 resistive elements in a series array.

Features of the X9428WP-2.7 are:(1)SOIC and TSSOP packages;(2)Resolution: 64 taps each potentiometer;(3)10 K Ohm resistor array;(4)4-bytes of nonvolatile memory;(5)High reliability: Endurance100,000 Data Changes per Bit per Register and Register Data Retention100 years;(6)Solid state potentiometer;(7)2-wire serial interface;(8)Register oriented format: Direct Read/Write/Transfer Wiper Position and Store as many as Four Positions per Potentiometer;(9)Low power CMOS: Standby current < 1A and Ideal for Battery Operated Applications.

The absolute maximum ratings of the X9428WP-2.7 can be summarized as:(1)Temperature under bias:65°C to +135°C;(2)Storage temperature:65°C to +150°C;(3)Voltage on SDA, SCL or any address input with respect to Vss: -1 V to +7 V;(4)Voltage on V+ (referenced to VSS): 10 V;(5)Voltage on V- (referenced to Vss): -10 V;(6)(V+) - (V-): 12 V;(7)Any VH/RH: V+;(8)Any VL/RL: V-;(9)Lead temperature (soldering, 10 seconds): 300°C;(10)IW (10 seconds): ±12 mA.
