PRODUCTION DATA.
The circuit requires an input capacitor to allow biasing of the amplifier put to the proper dc level. The input capacitor and the input impedance of the amplifier form a high-pass filter with a –3-dB corner frequency determined by the equation: f = 1 / (2πR(i)C(i)), where R(i) is the input impedance of the device based on the gain setting and C(i) is the input capacitor value. Table 10 lists largest recommended input capacitor values. Use a capacitor which matches the application need for the lowest frequency but does not exceed the values listed.
