The ADAU1328 is a high performance, single-chip codec that provides two analog-to-digital converters (ADCs) with differential input and eight digital-to-analog converters (DACs) with single-ended output using the Analog Devices, Inc. patented multibit sigma-delta (Σ-Δ) architecture. An SPI port is included, allowing a microcontroller to adjust volume and many other parameters. The ADAU1328 operates from 3.3 V digital and analog supplies. The ADAU1328 is available in a 48-lead (single-ended output) LQFP. Other members of this family include a differential DAC output version.The ADAU1328 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 clock or from an external crystal, the ADAU1328 eliminates the need for a separate high frequency master clock and can also be used with a suppressed bit clock. The digital-to-analog and analog-to-digital converters are designed using the latest ADI continuous time architectures to further minimize EMI. By using 3.3 V supplies, power consumption is minimized, further reducing emissions.APPLICATIONS Home theater systems Set-top boxes Digital audio effects processors

The ADF4002 frequency synthesizer is used to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters. It consists of a low-noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider and programmable N divider. The 14-bit reference counter (R counter), allows selectable REFIN frequencies at the PFD input.A complete phase-locked loop (PLL) can be implemented if the synthesizer is used with an external loop filter and voltage controlled oscillator (VCO). In addition, by programming R and N to 1, the device can be used as a standalone PFD and charge pump.The ADF4002-EP supports defense and aerospace applications (AQEC standard).

The ADG1206 and ADG1207 are monolithic iCMOS® analogmultiplexers comprising sixteen single channels and eightdifferential channels, respectively. The ADG1206 switches oneof sixteen inputs to a common output, as determined by the4-bit binary address lines A0, A1, A2, and A3. The ADG1207switches one of eight differential inputs to a common differentialoutput, as determined by the 3-bit binary address lines A0, A1,and A2. An EN input on both devices is used to enable or disablethe device. When disabled, all channels are switched off. Whenon, each channel conducts equally well in both directions andhas an input signal range that extends to the supplies.The industrial CMOS (iCMOS) modular manufacturingprocess combines high voltage complementary metal-oxide semiconductor (CMOS) and bipolar technologies.
