Okay, here's a summary of the key electrical characteristics of the TS488/TS489 audio amplifier, based on the provided text. I'll focus on the consistent parameters across different supply voltages (2.5V, 5V), and the variations.

Key Electrical Characteristics (TS488/TS489)

️· Supply Voltage: Tested at 2.5V and 5V.
️· ICC (Supply Current): 1.8mA - 2.5mA (no signal, varies with supply voltage).
️· ISTBY (Standby Current): 10nA - 1000nA (very low, varies with supply voltage).
️· Pout (Output Power): Varies significantly with supply voltage and THD+N level.
- At 2.5V with 0.1% THD+N: ~19mW (into 32Ω)
- At 2.5V with 1% THD+N: ~18-20mW (into 32Ω)
- At 5V with 0.1% THD+N: Not explicitly stated, but likely higher.
- At 5V with 1% THD+N: Not explicitly stated, but likely higher.
️· THD+N (Total Harmonic Distortion + Noise): Tested at various output power levels. Performance is consistent across voltages.
- 0.3% is a typical value at specified output power levels (10mW at 2.5V, 16mW at 2.5V)
️· PSRR (Power Supply Rejection Ratio): 66dB - 68dB. Consistent performance across supply voltages and frequencies.
️· VO (Output Swing): Varies with supply voltage.
- At 2.5V: ~0.12V - 0.28V (into 32Ω)
- At 5V: Not explicitly stated, but likely higher.
️· SNR (Signal-to-Noise Ratio): 100dB to 100dB at specified conditions.
️· GBP (Gain Bandwidth Product): 1.1MHz.

️· Slew Rate (SR): 0.6V/us.
️· Input Offset Voltage (VIO): 1V-20V
️· Wake-up time (twu): 100ms

Additional Notes:

️· The document includes a significant number of graphs (open-loop frequency response, power derating, SNR vs. voltage, THD+N vs. frequency, etc.).
️· The performance is tested with different load resistances (RL) and capacitances (CL).
️· The text is incomplete as it contains a table index and some table structures are not fully provided.
