LM : Single Channel. The is a cost effective high power amplifier suited for automotive applications High current capability 3 5A enables the device to drive low impedance loads with low distortion The LM is current limited and thermally protected High voltage protection is available LMA which enables the amplifier to withstand 40V transients on its supply The LM The is a two-stage differential input differential output wide-band video amplifier The use of internal series-shunt feedback gives wide bandwidth with low phase distortion and high gain stability Emitter-follower outputs provide a high current drive low impedance capability Its MHz bandwidth and selectable gains 10 and without need for frequency. It regenerates 3D surround sound from only stereo input.

CMOS Technology? Low Power Consumption? Least External Components? Operating Voltage: 5 to 9 V o? High Channel Separation. I2C Bus Control Interface z? Selectable Address d?
AV Surround Audio Equipment? Car Audio. Mini Compo? Computer Multi-Media Speaker www? I Channel Input No. C I Channel Input No. Ch O Channel Output No. It should be noted that the pull-up resistors must be connected to the positive supply voltage. Please refer to the figure below. D ATA z. C The Stop Condition is activated when 1. Each byte must be followed by an Acknowledge Bit.
The MSB is transmitted first. PT V1. Please refer to the diagram below. The audio processor that has been addressed has to generate an Acknowledge after receiving each byte, otherwise, the SDA Line will remain at the High Level during the ninth 9th Clock Pulse. In this case, the master transmitter can generate the STOP Information in order to abort the transfer. P transmission may d be used. Wait one clock and do not check the slave acknowledge of this same clock then send the new a data.
If you use this approach, there are greater chances of faulty operation as well as decrease in noise immunity. A Start bit w? A Chip Address Byte? A Data byte w? If the waiting time period is less than ms, I2C Control may fail. The PT function register does not have any default settings. After clearing the register, an initial value must send in order to each register.
If a register does has not been set, it is possible that no sound will be output. When adjusting the volume of PT, it is necessary to send a multiple of 10dB followed by a 1dB code to the attenuator in sequence. If this sequence is not followed, or if only a 10dB or 1dB value is m sent, the IC may not operate normally. Please refer to the diagram below: o Volume setting dBj. Stop Stop in Warning!!
The following transmission method is not permitted. Input Voltage VCL. F - Max. F I2C Bus 10? F om 10? F www. Com 2. The Lead Free mark is put in front of the date code. Com PT V1. Mold flash or protrusions w shall not exceed 0. Pointed or rounded lead tips are preferred to ease insertion.
Dambar protrusions shall not exceed 0. Distance between leads including dambar protrusions to be 0. Datum plane -H- coincident with the bottom of lead, where lead exits body. Mold Flash, protrusion or gate burrs shall not exceed 0.
Interlead flash or protrusions shall not exceed 0. The chamfer on the body is optional. It is not present, a visual index feature must be located within the crosshatched area.

Although the global semiconductor industry since , growth has slowed, the growth rate affected the domestic industry also declined, but still much higher than the global average. In the "One Man fiscal ," under the guidance of the policy, if the price can get some control of the wafer, then the growth rate of the semiconductor industry may exceed expectations. They suggested that attention to the current listing of silicon wafer manufacturers have research unit, Central shares. MPCxM device based on Power Architecture TM technology, not only enhanced powertrain functionality, such as on-chip emissions control, but also to meet the engine and transmission business for the supply of cost constraints. These cost-effective devices are Freescales 90 nanometer technology based on the first production car MCU products; but also from January Freescale and STMicroelectronics launched a joint development project, the production of the first automotive products. Rivet said: "The Suzhou plant expansion is not only the development of the factory pre-and technical quality important manifestation of a high degree of identity, but also AMD outstanding technical talents in China and recognized the market potential.
