The AD1937 is a high performance, single-chip codec that provides four analog-to-digital converters (ADCs) with differential input and eight digital-to-analog converters (DACs) with differential output, using the Analog Devices, Inc., patented multibit sigma-delta (?-?) architecture. An I2C? port is included, allowing a microcontroller to adjust volume and many other parameters. The AD1937 operates from 3.3 V digital and analog supplies. The AD1937 is available in a 64-lead (differential output) LQFP.The AD1937 is designed for low EMI. This consideration is apparent in both the system and circuit design architectures. By using the on-board PLL to derive the master clock from the LR (frame) clock or from an external crystal, the AD1937 eliminates the need for a separate high frequency master clock and can also be used with a suppressed bit clock. The DACs and ADCs are designed using the latest Analog Devices continuous time architecture to further minimize EMI. By using 3.3 V supplies, power consumption is minimized and further reduces emissions.ApplicationsAutomotive audio systems Home theater systemsSet-top boxesDigital audio effects processorsData Sheet, Rev. 0, 9/08

The short and long term reliability of National Semiconductor's interface circuits like any integrated circuit is very dependent on its environmental condition. Beyond the mechanical/environmental factors nothing has a greater influence on this reliability than the electrical and thermal stress seen by the integrated circuit. Both of these stress issues are specifically addressed on every inter

DC2985A is a multi-output power management solution demonstration circuit, featuring the LT3380. It contains two 2.5A, two 1.5A synchronous step-down DC/DC regulators and three 300mA LDO regulators. All regulators can be enabled with external enable pins. After the first regulator is enabled, the remaining enable pins use a precision threshold to allow hardwire-programmed Power-Up Sequence. A micro-USB communication interface is integrated on board to allow software GUI to write or read the registers in LT3380 via its I2C serial port. This GUI can control regulator enables, power-down sequencing, output voltage levels, dynamic voltage scaling, operation modes, status reporting and other special functions. Refer to LT3380 data sheet for more details on the electrical specifications and the setting of its command registers.

This design is a digitally controlled: bridgeless: 300W: power factor correction (PFC) converter. The distinguishing characteristic of a bridgeless PFC converter is that it eliminates the need for a diode bridge at the input. This reduces power losses that normally occur in a diode bridge and: as a result: improves overall system efficiency. For this design: a C2000™ Piccolo™ TMS320F28035 microcontroller (MCU) is the digital controller for the PFC converter: controlling the two boost power stages that comprise the bridgeless PFC converter. By operating the stages alternatively during the positive and negative half cycles of the AC mains voltage: the Piccolo MCU implements both the AC-to-DC rectification as well as power factor control. This design achieves full load efficiency greater than 93% and power factor of greater than 0.98 at 50% or greater load.
