PERFORMANCE VARIATIONS
The LME49724 has excellent performance with little variation
across different supply voltages, load impedances, and input
configuration (single-ended or differential). Inspection of the
THD+N vs Frequency and THD+N vs Output Voltage perfor-
mance graphs reveals only minimal differences with different
load values. Figures 7 and 8 below show the performance
across different supply voltages with the same output signal
level and load. Figure 7 has plots at ±5V, ±12V, ±15V, and
±18V with a 3V
±15V, and ±18V with a 10V
600Ω load. The performance for each different supply voltage
under the same conditions is so similar it is nearly impossible
to discern the different plots lines.

Whether the input configuration is single-ended or differential
has only a minimal affect on THD+N performance at higher
audio frequencies or higher signal levels. For easy compari-
son, Figures 9 and 10 are a combination of the performance
graphs found in the Typical Performance Characteristics sec-
tion above.
