STEVAL-CCA003V1 数据手册
STEVAL-CCA003V1 Low-voltage stereo audio power amplifier based on the TS4984 Data Brief Features ■ Operates from VCC=2.2 V to 5.5 V ■ 1 W output power per channel @ VCC=5 V, THD+N=1%, RL= 8 Ω ■ 10 nA standby current ■ 62 dB PSRR @ 217 Hz with grounded inputs ■ High SNR: 100 dB (A-weighted filter) typ. ■ Near-zero pop and click ■ Available in the QFN16 4x4 mm, 0.5 mm pitch, lead-free package ) s ( ct u d o r P e t e l o Description This evaluation board is designed for the TS4984 stereo audio power amplifier. The micro-package QFN16 (quad, flat, non-leaded, 16-pin) combines space-saving with good thermal dissipation. The BTL gain is set at 2 V for both channels and can be adapted if necessary with a modification of R1/ R8 or R2/R6 values for the left/right channels. The R3/R6 and C3/C5 component locations are empty on the board to allow changes to both input configurations from single-ended to differential. For use in differential mode, R4/R7 must be modified. The C1/C6 component locations are also left empty so that, if required, a low-pass filter can be added. ) (s s b O t c u STEVAL-CCA003V1 d o r P e t e l o s b O January 2008 Rev 1 For further information contact your local STMicroelectronics sales office. 1/4 www.st.com 4 Circuit schematic 1 STEVAL-CCA003V1 Circuit schematic Figure 1.
