1 For supply voltages less than ±18 V, the absolute maximum input voltage is

equal to the supply voltage. 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 indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Table 3.

ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

Rev. F | Page 13 of 16 PROGRAMMABLE STATE-VARIABLE FILTER The circuit shown in Figure 46 can be used to accurately program the Q, the cutoff frequency fC, and gain of a 2-pole state variable filter. OP482s have been used in this design because of their high bandwidths, low power, and low noise. This circuit takes only three packages to build because of the quad configuration of the op amps and DACs. The DACs shown are used in the voltage mode; therefore, many values are dependent on the accuracy of the DAC only and not on the absolute values of the DAC’s resistive ladders. This makes this circuit unusually accurate for a programmable filter. Adjusting DAC 1 changes the signal amplitude across R1; therefore, the DAC attenuation times R1 determines the amount of signal current that charges the integrating capacitor, C1. This cutoff frequency can now be expressed as ⎞⎜⎝ ⎛= 2562π 1 D1 R1C1fc where D1 is the digital code for the DAC. The gain of this circuit is set by adjusting D3. The gain equation is ⎞⎜⎝ ⎛= 256 R4Gain DAC 2 is used to set the Q of the circuit. Adjusting this DAC controls the amount of feedback from the band-pass node to the input summing node. Note that the digital value of the DAC is in the numerator; therefore, zero code is not a valid operating point. ⎞⎜⎝ ⎛= D2R3 R2Q 256 2kΩ1/4 OP482 VIN DAC8408 HIGH PASS 1000pF 2kΩ 2kΩ 2kΩ OP482 R1 2kΩ1/4 OP482 DAC8408 1/4 OP482 R1 2kΩ1/4 OP482 DAC8408 1/4 OP482 1000pF LOW PASS OP4821/4 OP482 DAC8408 BAND PASS 2kΩ 2kΩ 00301-048 Figure 46.
