简  介:Low Noise, Low Power, 32 Taps X9316 E2POT Nonvolatile Digital Potentiometer FEATURES Low Micropower CMOS —VCC = 3V to 5.5V —Active Current, 50A (Increment) Max —Standby Current, 400 A (Store) Max Low Noise 31 Resistive Elements —Temperature Compensated — ± 20% End to End Resistance Range —–5V to +5V 32 Wiper Tap Points —Wiper Positioned via Three-Wire Interface —Similar to TTL Up/Down Counter —Wiper Position Stored in Nonvolatile Memory and Recalled on Power-Up 100 Year Wiper Position Data Retention X9316Z = 1K X9316W = 10K Packages —14-Lead PDIP —14-Lead SOIC FUNCTIONAL DIAGRAM DESCRIPTION The Xicor X9316 is a solid state “micropower” nonvolatile potentiometer and is ideal for digitally controlled resistance trimming in battery-powered systems. The X9316 is a resistor array composed of 31 resistive elements. Between each element and at either end are tap points accessible to the wiper element. The position of the wiper element is controlled by the CS, U/D, and INC inputs. The position of the wiper can be stored in nonvolatile memory and then be recalled upon a subsequent power-up operation. The resolution of the X9316 is equal to the maximum resistance value divided by 31. As an example, for the X9316W (10K) each tap point represents 323. All Xicor nonvolatile memories are designed and tested for applications requiring extended endurance and data retention.
