8.2 Typical Application

The low power consumption, noise, and distortion of the OPA169x family of audio operational amplifiers make the family a viable option for a number of analog audio circuits. Figure 60 shows one circuit example, which shows a preamplifier circuit that is designed for high-performance electret microphones that use a 3-wire interface.
