STEVAL-CCA037V1

STEVAL-CCA037V1 Amplifier based on the TS4990IQT Data brief Features Operating from V = 2.2 V to 5.5 V CC Active low standby mode 1.2 W output power V = 5 V, THD = 1%, CC F = 1 kHz, with 8 load Ultra low power consumption in standby mode (10 nA) 62dB PSRR 217 Hz in grounded mode (A = 2 V/V) v Near zero pop and click Ultra low distortion (0.1%) Module gain set at 2 V/V Thermal and short-circuit protection RoHS compliant Description The STEVAL-CCA037V1 demonstration board is designed to evaluate the TS4990IQT low power audio amplifier. The micro package DFN8 (dual flat non-leaded 8 pins) allows space saving and good thermal dissipation. The BTL gain is set at 2 V/V and can be adapted if necessary with a modification of two (R1 or R2) resistor values. It is possible to modify the input configuration from single ended to differential of the STEVAL- CCA037V1 demonstration board. More information regarding component calculations is available in the TS4990 datasheet.
