Optical disc ICs
1-channel BTL driver for CD players
BA6195FP-Y / BA6195
The BA6195FP-Y and BA6195 are ICs for CD players and have one internal BTL power driver circuit and one operational
amplifier circuit with a wide output dynamic range. The wide dynamic range and internal operational amplifier make these
ICs ideal for low voltage drive. The driver’s internal level shift circuit reduces the number of attached components need-
ed.
FApplications
CD players, CD-ROM drives and other optical disc devices
FFeatures
1) HSOP 25-pin power package allows for miniaturiza-
tion of applications (BA6195FP-Y).
2) Wide dynamic range. (typically 5.4V when VCC = 8V,
RL = 8Ω)
3) Internal thermal shutdown circuit with hysteresis.
4) Internal level shift circuit, for a minimal number of at-
tached components.
5) Internal operational amplifier with wide dynamic
range.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)

FOperation notes
1) The thermal shutdown circuit mutes the output cur-
rent when the chip temperature rises above 175_C (typi-
cally). Hysteresis width is set at 25_C (typically), and
muting is canceled when the chip temperature drops be-
low 150_C.
2) The output current can be muted by raising the ex-
ternal mute pin above 2.0V. Pin 14 should be pulled down
below 0.5V during normal operation.

3) Muting occurs during thermal shutdown and exter-
nal muting. In each case, only the drivers are muted. Dur-
ing muting, the output pins remain at the internal bias
voltage, roughly (VCC / 2).
4) Connect the IC to a 0.1µF bypass capacitor to the
power supply, at the base of the IC.
5) Connect the radiating fin to an external ground
(BA6195FP-Y).
