General Description

s BA6997FP/BA6997FM 405 Optical disc ICs BA6997FP/BA6997FM FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC = 8V, f = 1kHz, RL = 8Ω) 406 Optical disc ICs FApplication example BA6997FP/BA6997FM 407 Optical disc ICs FOperation notes (1) The BA6997FP and BA6997FM have an internal thermal shutdown circuit.

Output current is muted when the chip temperature exceeds 175_C (typically).

(2) The output current can be muted by opening the mute pin (pin 9) voltage or lowering it below 0.5V.
