Note 1. The internal circuit impedance at Pin11 is > 5k

Note 2. Closed–Loop voltage gain can be chosen between 32 and 56dB (BTL), and is determined

by external components.

Note 3. Without the bootstrap the 100

µF capacitor between Pin5 and Pin6 (Pin8 and Pin9) can be

omitted. Pin6, Pin8, and Pin10 have to be interconnected.

Note 4. Frequency response externally fixed.

Note 5. The input impedance in the test circuit is typically 100k

Ω.
