11 / 21 page X9409 – Preliminary Information Characteristics subject to change without notice. 11 of 21 REV 1.6 1/30/03 www.xicor.com ABSOLUTE MAXIMUM RATINGS Temperature under bias ....................–65°C to +135°C Storage temperature .........................–65°C to +150°C Voltage on SDA, SCL or any address input with respect to VSS.........................–1V to +7V ∆ V = |VH – VL |........................................................ 5V Lead temperature (soldering, 10 seconds).........300°C COMMENT Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only; functional operation of the device (at these or any other conditions above those listed in the operational sections of this specification) is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. RECOMMENDED OPERATING CONDITIONS Temperature Min. Max. Commercial 0 °C +70 °C Industrial –40 °C +85 °C Device Supply Voltage (VCC) Limits X9409 5V ±10% X9409-2.7 2.7V to 5.5V ANALOG CHARACTERISTICS (Over recommended operating conditions unless otherwise stated.)

Unit End to end resistance tolerance ±20 % Power rating 15 mW 25°C, each pot @5V, 2.5K IW Wiper current -3 +3 mA RW Wiper resistance 50 150 Ω IW = ± 3mA, VCC = 3V to 5V VTERM Voltage on any VH/RH or VL/RL pin VSS VCC VVSS = 0V Noise -120 dBV Ref: 1kHz Resolution (4) 1.6 % Absolute linearity (1) -1 +1 MI(3) Vw(n)(actual)—Vw(n)(expected) Relative linearity (2) -0.2 +0.2 MI(3) Vw(n + 1)—[Vw(n) + MI] Temperature coefficient of RTOTAL ±300 ppm/°C Ratiometric temp. coefficient 20 ppm/°C CH/CL/CW Potentiometer capacitances 10/10/25 pF See Macro Model IAL RH, RL, RW leakage current 0.1 10 µA VIN = VSS to VCC. Device is in stand-by mode. Notes: (1) Absolute Linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a potentiometer. (2) Relative Linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a potenti- ometer. It is a measure of the error in step size. (3) MI = RTOT/63 or (VH—VL)/63, single pot |
