Stereo 1.2W Audio Sub-System with 3D Enhancement
LM4844 datasheet
Description
The LM4844 is an integrated audio sub-system designed for stereo cell phone applications. Operating on a 3.3V supply, it combines a stereo speaker amplifier delivering 495mW per channel into an 8Ω load and a stereo OCL headphone amplifier delivering 33mW per channel into a 32Ω load.
It integrates the audio amplifiers, volume control, mixer, power management control, and National 3D enhancement all into a single package. In addition, the LM4844 routes and mixes the stereo and mono inputs into 10 distinct output modes. The LM4844 is controlled through an I 2C compatible interface.
Boomer audio power amplifiers are designed specifically to provide high quality output power with a minimal amount of external components.
The LM4844 is available in a very small 2.5mm x 2.9mm 30-bump micro SMD (TL) package.

DARLINGTON TRANSISTOR ARRAY
The ULN2003 is a monolithic high voltage and high current
Darlington transistor arrays. It consists of seven NPN darlington
pairs that features high-voltage outputs with common-cathode
clamp diode for switching inductive loads. The collector-current
rating of a single darlington pair is 500mA. The darlington pairs
may be parrlleled for higher current capability. Applications include
relay drivers,hammer drivers, lampdrivers,display drivers(LED gas
discharge),line drivers, and logic buffers.

IR2110 DATASHEET
ir2110 datasheet
HIGH AND LOW SIDE DRIVER
IR2110(-1-2)(S)PbF/IR2113(-1-2)(S)PbF
• Floating channel designed for bootstrap operation
Fully operational to +500V or +600V
Tolerant to negative transient voltage
dV/dt immune
• Gate drive supply range from 10 to 20V
• Undervoltage lockout for both channels
• 3.3V logic compatible
Separate logic supply range from 3.3V to 20V
Logic and power ground ±5V offset
• CMOS Schmitt-triggered inputs with pull-down
• Cycle by cycle edge-triggered shutdown logic
• Matched propagation delay for both channels
• Outputs in phase with inputs
Description
The IR2110/IR2113 are high voltage, high speed power MOSFET and
IGBT drivers with independent high and low side referenced output chan-
nels. Proprietary HVIC and latch immune CMOS technologies enable
ruggedized monolithic construction. Logic inputs are compatible with
standard CMOS or LSTTL output, down to 3.3V logic. The output
drivers feature a high pulse current buffer stage designed for minimum
driver cross-conduction. Propagation delays are matched to simplify use in high frequency applications. The
floating channel can be used to drive an N-channel power MOSFET or IGBT in the high side configuration which
operates up to 500 or 600 volts
