LM4916
1.5V, Mono 85mW BTL Output, 14mW Stereo Headphone
Audio Amplifier
General Description
The unity gain stable LM4916 is both a mono differential
output (for bridge-tied loads or BTL) audio power amplifier
and a Single Ended (SE) stereo headphone amplifier. Oper-
ating on a single 1.5V supply, the mono BTL mode delivers
85mW into an 8
load at 1% THD+N. In Single Ended stereo
headphone mode, the amplifier delivers 14mW per channel
into a 16
load at 1% THD+N.
With the LM4916 packaged in the MM and LLP packages,
the customer benefits include low profile and small size.
These packages minimize PCB area and maximizes output
power.
The LM4916 features circuitry that reduces output transients
("clicks" and "pops") during device turn-on and turn-off, an
externally controlled, low-power consumption, active-low
shutdown mode, and thermal shutdown. Boomer audio
power amplifiers are designed specifically to use few exter-
nal components and provide high quality output power in a
surface mount package.
