AUDIO APPLICATIONS
The OPA363 and OPA364 op amp family has linear offset voltage over the entire input common-mode range.
Combined with low-noise, this feature makes the OPA363 and OPA364 suitable for audio applications. Single
supply 1.8V operation allows the OPA2363 and OPA2364 to be optimal candidates for dual stereo-headphone
drivers and microphone pre-amplifiers in portable stereo equipment, see Figure 29 and Figure 30.
