ADZS-AD2428MINI is a low-cost, mini break-out board which can interface with EV-SOMCRR-EZKIT (via a 100-pin connector) or any custom board (via a 32 pin 0.1" header). It supports main and subordinate node capability as well as bus and local power configurations. An Automotive Audio Bus (A2B®) system consists of a single main node and at least one subordinate node, where the transceiver at the host controller is the main node. The main transceiver generates clock, synchronization, and framing for all subordinate nodes and is programmable over a control bus (I2C) for configuration and readback. An extension of this control bus is embedded in the A2B data stream, which enables the host to directly access subordinate transceiver registers and any I2C-connected peripherals on subordinate nodes. Transceivers can connect directly to PDM microphones and to numerous peripherals via I2C and a multichannel I2S/TDM interface. Finally, the transceiver also supports an A2B bus powering feature, where the main node supplies voltage and current to the subordinate nodes over the same daisy-chained, twisted pair wire cable as used for the communication link, thus eliminating the need for a power supply on bus-powered subordinate nodes. Due to the numerous configurations that are possible for a given A2B system, there are several evaluation platforms that can be used in combination to verify system operation, as summarized in the table below.

The LTC1066-1 is an 8th order elliptic lowpass filter which simultaneously provides clock-tunability and DC accuracy. The unique and proprietary architecture of the filter allows 14 bits of DC gain linearity and a maximum of 1.5mV DC offset. An external RC is required for DC accurate operation. With ?7.5V supplies, a 20k resistor and a 1?F capacitor, the cutoff frequency can be tuned from 800Hz to 100kHz. A clock-tunable 10Hz to 100kHz operation can also be achieved (see Typical Application section).The filter does not require any external active components such as input/output buffers. The input/output impedance is 500M?/0.1? and the output of the filter can source or sink 40mA. When pin 8 is connected to V+ , the clock-to-cutoff frequency ratio is 50:1 and the input signal is sampled twice per clock cycle to lower the risk of aliasing. For frequencies up to 0.75fCUTOFF , the passband ripple is ?0.15dB. The gain at fCUTOFF is -1dB and the filter?s stopband attenuation is 80dB at 2.3fCUTOFF . Linear phase operation is also available with a clock-to-cutoff frequency ratio of 100:1 when pin 8 is connected to ground.The LTC1066-1 is available in an 18-pin SO Wide package..Applications Instrumentation Data Acquisition Systems Anti-Aliasing Filters Smoothing Filters Audio Signal Processing

The LT1372/LT1377 are monolithic high frequency switching regulators. They can be operated in all standard switching configurations including boost, buck, flyback, forward, inverting and 'Cuk.' A 1.5A high efficiency switch is included on the die, along with all oscillator, control and protection circuitry. All functions of the LT1372/LT1377 are integrated into 8-pin SO/PDIP packages.The LT1372/LT1377 typically consumes only 4mA quiescent current and has higher efficiency than previous parts. High frequency switching allows for very small inductors to be used. All surface mount components consume less than 0.5 square inch of board space.New design techniques increase flexibility and maintain ease of use. Switching is easily synchronized to an external logic level source. A logic low on the shutdown pin reduces supply current to 12?A. Unique error amplifier circuitry can regulate positive or negative output voltage while maintaining simple frequency compensation techniques. Nonlinear error amplifier transconductance reduces output overshoot on start-up or overload recovery. Oscillator frequency shifting protects external components during overload conditions.Applications Boost Regulators CCFL Backlight Driver Laptop Computer Supplies Multiple Output Flyback Supplies Inverting Supplies

The LTC1174 is a simple current mode DC/DC converter ideally suited for 9V to 5V, 5V to 3.3V or 5V to ?5V operation. With an internal 0.9? switch (at a supply voltage of 9V), the LTC1174 requires only four external components to construct a complete high efficiency DC/DC converter.Under a no load condition the LTC1174 draws only 130?A. In shutdown, it draws a mere 1?A making this converter ideal for current sensitive applications. In dropout, the internal P-channel MOSFET switch is turned on continuously allowing the user to maximize the life of the battery source.The maximum inductor current of the LTC1174 family is pin selectable to either 340mA or 600mA, optimizing efficiency for a wide range of applications. Operation up to 200kHz permits the use of small surface mount inductors and capacitors.For applications requiring higher output current or ultrahigh efficiency, see the LTC1148 data sheet.Applications Distributed Power Systems Step-Down Converters Inverting Converters Memory Backup Supply Portable Instruments Battery-Powered Equipment
