1 / 15 page Semiconductor Components Industries, LLC, 2013 July, 2013 − Rev. 11 1 Publication Order Number: CAT5419/D CAT5419 Dual Digital Potentiometer (POT) with 64 Taps and 2‐wire Interface Description The CAT5419 is two digital POTs integrated with control logic and 16 bytes of NVRAM memory. A separate 6-bit control register (WCR) independently controls the wiper tap position for each digital POT. Associated with each wiper control register are four 6-bit non-volatile memory data registers (DR) used for storing up to four wiper settings. Writing to the wiper control register or any of the non-volatile data registers is via a 2-wire serial bus (I2C-like). On power-up, the contents of the first data register (DR0) for each of the two potentiometers is automatically loaded into its respective wiper control registers (WCR). The Write Protection (WP) pin protects against inadvertent programming of the data register. The CAT5419 can be used as a potentiometer or as a two terminal, variable resistor. It is intended for circuit level or system level adjustments in a wide variety of applications. Features Two Linear-taper Digital Potentiometers 64 Resistor Taps per Potentiometer End to End Resistance 2.5 kW, 10 kW, 50 kW or 100 kW Potentiometer Control and Memory Access via 2-wire Interface (I2C like) Low Wiper Resistance, Typically 80 W Four Non-volatile Wiper Settings for Each Potentiometer Recall of Wiper Settings at Power Up 2.5 to 6.0 Volt Operation Standby Current less than 1 mA 1,000,000 Nonvolatile WRITE Cycles 100 Year Nonvolatile Memory Data Retention 24-lead SOIC and 24-lead TSSOP Write Protection for Data Register These Devices are Pb-Free, Halogen Free/BFR Free and are RoHS Compliant http://onsemi.com TSSOP24 Y SUFFIX CASE 948AR PIN CONNECTIONS SOIC−24 (W) (Top View) NC VCC RL0 RH0 1 RW0 A2 NC NC NC A0 SOIC−24 W SUFFIX CASE 751BK See detailed ordering and shipping information in the package dimensions section on page 13 of this data sheet.
