X9317 Low Noise, Low Power, 100 Taps Digitally Controlled Potentiometer (XDCP™) The Intersil X9317 is a digitally controlled potentiometer (XDCP). The device consists of a resistor array, wiper switches, a control section, and nonvolatile memory. The wiper position is controlled by a 3-wire interface. The potentiometer is implemented by a resistor array composed of 99 resistive elements and a wiper switching network. Between each element and at either end are tap points accessible to the wiper terminal. 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 device can be used as a three-terminal potentiometer for voltage control or as a two-terminal variable resistor for current control in a wide variety of applications. Features • Solid-State Potentiometer • 3-Wire Serial Up/Down Interface • 100 Wiper Tap Points - Wiper position stored in nonvolatile memory and recalled on power-up • 99 Resistive Elements - Temperature compensated - End to end resistance range ±20% • Low Power CMOS -VCC = 2.7V to 5.5V, and 5V ±10% - Standby current < 1µA • High Reliability - Endurance, 100,000 data changes per bit - Register data retention, 100 years •RTOTAL Values = 1kΩ, 10kΩ, 50kΩ, 100kΩ • Packages - 8 Ld SOIC, DIP, TSSOP, and MSOP • Pb-Free Plus Anneal Available (RoHS Compliant) Applications • LCD Bias Control • DC Bias Adjustment • Gain and Offset Trim • Laser Diode Bias Control • Voltage Regulator Output Control Pinouts X9317 (8 LD TSSOP) TOP VIEW X9317 (8 LD DIP, 8 LD SOIC, 8 LD MSOP) TOP VIEW INC RL/VL CS VCC 1 2 3 4 8 7 6 5 X9317 U/D RW/VW VSS RH/VH RH VCC INC U/D 1 2 3 4 8 7 6 5 X9317 VSS CS RL RW Data Sheet September 9, 2005 |
