MSP430F149-JTAG
The Texas Instruments MSP430 ultra-low power microcontroller family consists of several devices with different peripheral sets targeted for various applications. Combined with five low power modes, the architecture is optimized to achieve longer battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and fixed generators attributed to maximum code efficiency. The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 6 µs.
The MSP430x13x and MSP430x14x(1) series are microcontroller configurations that include two internal 16-bit timers, a fast 12-bit A/D converter (not implemented in the MSP430F14x1 devices), one or two universal serial synchronous/asynchronous communication interfaces (USART), and 48 I/O pins.

DAC Circuit CS8416 CS4398
Digital audio applications have not done anything but CS8416 (192 kHz Digital Audio Receiver) and CS4398 (CS4398: 120 dB, 24-Bit, 192 kHz Stereo D / A Converter) integrated carried out with the DAC module circuitry of the person concerned may be useful to PCB drawing is so much quality
What is the DAC?
DAC, DAC or D-to-A (Digital to Analog Converter) that can be translated into our language as digital-to-analog converter is a special identification. Especially since the emergence of the CD, the media having the recorded data due to digital data converted into analog has been used for the purpose. Mounted into the chassis of a CD player, although as will be used as a separate device. In particular, appears in separate use professional equipment. The purpose of the CD reading mechanisms of mechanical vibrations and other electronic components inside the device during the digital to analog conversion is to minimize interaction. With different technologies, though, CD, SACD, DVD-like digital recording platforms all used to do
