X9421WS-2.7

The X9421WS-2.7 is one member of the X9420 family which is designed as the single digitally controlled (XDCP) 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. Also this device is implemented using 63 resistive elements in a series array.

Features of the X9421WS-2.7 are:(1)single voltage potentiometer; (2)64 resistor taps; (3)SPI serial interface for write, read, and transfer operations of the potentiometer; (4)wiper resistance, 150 typical at 5V; (5)4 non-volatile data registers; (6)non-volatile storage of multiple wiper positions; (7)power on recall. loads saved wiper position on power up; (8)standby current < 5 uA max; (9)Vcc: 2.7V to 5.5V operation; (10)2.5K, 10K end to end resistance; (11)100 yr. data retention; (12)endurance: 100, 000 data changes per bit per register; (13)14-lead TSSOP, 16-lead SOIC; (14)low power CMOS.

The absolute maximum ratings of the X9421WS-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 SCK, SCL or any address input with respect to Vss:1 V to +7 V;(4)Lead temperature (soldering, 10 seconds): 300°C;(5)IW (10 seconds): ±6 mA.
