PERFORMANCE SPECIFICATIONS

(Full-Scale Output Sine Wave, 997 Hz, MCLK = 12.288 MHz, Measurement Bandwidth 10 Hz to 20 kHz, unless

otherwise specified; Fs for Single-Speed Mode = 48 kHz, SCLK = 3.072 MHz; Fs for Double-Speed Mode =

96 kHz, SCLK = 6.144 MHz. Test load RL= 16

Ω, CL = 10 pF. Performance results are measured in production

using a 4700

µF capacitor on the VA_HPx pins. Results will be degraded if smaller value capacitors are used.)
