SLLS801A – JUNE 2008 – REVISED JUNE 2008 MIN TYP MAX UNIT Half-bridge supply, PVDD_X DC supply voltage 8 18 23 V VSS Supply for Protection and I/O Logic, VREG DC supply voltage 3 3.3 3.6 V RL (BTL) 6-8 Output filter: L = 10 µH, C = 470 nF. RL (SE) Load impedance Output AD modulation, switching 3-4 Ω frequency > 350 kHz RL (PBTL) 3-4 LO (BTL) 200 Minimum output inductance under LO (SE) Output-filter inductance 200 nH short-circuit condition LO (PBTL) 200 FPWM PWM frame rate 192 384 432 kHz TJ Junction temperature 0 125 °C PVDD_X = 18 V, BTL mode, RL = 8 Ω, ROC = 22 KΩ, CBST = 33-nF, audio frequency = 1 kHz, AES17 filter, FPWM = 384 kHz, ambient temperature = 25°C (unless otherwise noted). Audio performance is recorded as a chipset, using TAS5086 PWM processor with an effective modulation index limit of 96.1%. All performance is in accordance with recommended operating conditions, unless otherwise specified. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT PVDD = 18 V, 10% THD 20 PVDD = 18 V, 7% THD 18 PO Power output per channel W PVDD = 12 V, 10% THD 9 PVDD = 12 V, 7% THD 8 PVDD = 18V, Po =10 W (half-power) 0.15 THD+N Total harmonic distortion + noise PVDD = 12V, Po =4.5 W (half-power) 0.18 % 1 W 0.05 Vn Output integrated noise A-weighted 50 µV SNR Signal-to-noise ratio (1) A-weighted 94 105 dB A-weighted, input level = –60 dBFS using DNR Dynamic range 94 105 dB TAS5086 modulator PD Power dissipation due to idle losses (IPVDD_X) PO = 0 W, 4 channels switching (2) 0.6 W (1) SNR is calculated relative to 0-dBFS input level. (2) Actual system idle losses are affected by core losses of output inductors.
