1 / 11 page Semiconductor Components Industries, LLC, 2013 July, 2013 − Rev. 8 1 Publication Order Number: CAT5120/D CAT5120, CAT5121, CAT5122 16‐tap Digital Potentiometers (POTs) with 2‐wire Interface Description CAT5120/5121/5122 linear-taper digital POTs perform the same function as a mechanical potentiometer or a variable resistor. These devices consist of a fixed resistor and a wiper contact with 16-tap points that are digitally controlled through a 2-wire up/down serial interface. The CAT5120 is configured as a potentiometer. The CAT5121 and CAT5122 are configured as variable resistors. See Pin Configurations for part functionality. Two resistance values are available: 10 k W and 50 kW. These are available in space-saving 5-pin and 6-pin SC−70 and SOT−23 packages. Features 0.3 mA Ultra-low Standby Current Single-supply Operation: 2.7 V to 5.5 V Glitchless Switching between Resistor Taps Power-on Reset to Midscale 2-wire Up/Down Serial Interface Resistance Values: 10 kW, 50 kW Available in SC−70 and SOT−23 Packages These Devices are Pb-Free, Halogen Free/BFR Free and are RoHS Compliant Applications LCD Screen Adjustment Volume Control Mechanical Potentiometer Replacement Gain Adjustment Line Impedance Matching http://onsemi.com SC−70 SD SUFFIX CASE 419AD PIN CONFIGURATIONS SOT−23 TB SUFFIX CASE 527AJ SC−70 SD SUFFIX CASE 419AC SOT−23 TB SUFFIX CASE 527AH GND H 2 CAT5122 16 1 5 34 2 3 4 W 5 CAT5120 SC−70 SOT−23 1 6 2 L 5 CAT5121 3 4 See detailed ordering and shipping information in the package dimensions section on page 7 of this data sheet.
