The wide dynamic range of the LM allows easy control of the output pulse width in the Pulse Width Modulator of Fig- ure For generating I ABC over a range of 4 to 6 decades of cur- rent, the system of Figure 31 provides a logarithmic current out for a linear voltage in. The differential voltage between Q1 and Q2 is attenuated by the R1, R2 network so that A1 may be assumed to be oper- ating within its linear range.
From Equation 5the input volt- age to A1 is: The voltage on the base of Q1 is then The ratio of the Dagasheet and Q2 collector currents is defined by: Combining and solving for I ABC yields: This logarithmic current can be used to bias the circuit of Fig- ure 4 provide a temperature independent stereo attenuation characteristic.
