NOTES:
1. Compressor is tested in production with 50kΩ load.
2. Not tested in production.
3. Offset values are identical for both gain states of noise reduction circuit.
4. Operational down to V_CC = 2V.
AC ELECTRICAL CHARACTERISTICS
T_A = 25^oC, V_CC = +3.0V, 0dB level = 77.5mV_RMS. See test circuit, Figure 6.
