CAT5241WI-10

The CAT5241WI-10 is one member of the CAT5241 family which is designed as the quad digitally programmable potentiometer that can be used as a potentiometer or as a two terminal, variable resistor. This device consists of a series of 63 resistive elements connected between two externally accessible end points, and is intended for circuit level or system level adjustments in a wide variety of applications.

Features of the CAT5241WI-10 are:(1)Automatic recall of saved wiper settings at power up; (2)2.5 to 6.0 volt operation; (3)Standby current less than 1A; (4)1,000,000 nonvolatile WRITE cycles; (5)100 year nonvolatile memory data retention; (6)20-lead SOIC and TSSOP packages; (7)Industrial temperature range; (8)Four linear-taper digitally programmable potentiometers; (9)64 resistor taps per potentiometer; (10)End to end resistance 2.5k, 10k, 50k or 100k; (11)Potentiometer control and memory access via 2-wire interface; (12)Low wiper resistance, typically 80; (13)Nonvolatile memory storage for up to four wiper settings for each potentiometer.

The absolute maximum ratings of the CAT5241WI-10 can be summarized as:(1)Temperature Under Bias: -55°C to +125°C;(2)Storage Temperature: -65°C to +150°C;(3)Voltage on any Pin with Respect to Vss: -2.0 V to +Vcc +2.0 V;(4)Vcc with Respect to Ground: -2.0 V to +7.0 V;(5)Package Power Dissipation Capability (TA = 25°C): 1.0 W;(6)Lead Soldering Temperature (10 secs): 300°C;(7)Wiper Current: +/- 12 mA.

The electrical characteristics of CAT5241WI-10 can be summarized as:(1)Power Supply Current: 1 mA;(2)Standby Current (VCC = 5.0V): 1 A;(3)Input Leakage Current: 10 A;(4)Output Leakage Current: 10 A;(5)Input Low Voltage: -1 to Vcc x 0.3 V;(6)Input High Voltage: Vcc x 0.7 Vcc + 1.0 V;(7)Output Low Voltage (Vcc = 3.0V): 0.4 V.
