The AD1974 is a high performance, single-chip ADC that provides four analog-to-digital converters (ADCs) with differential inputs using the Analog Devices, Inc. patented multibit sigma-delta (Σ-Δ) architecture. An SPI port is included, allowing a microcontroller to enable mutes and adjust many other parameters. The AD1974 operates from 3.3 V digital and analog supplies. The AD1974 is available in a single-ended output 48-lead LQFP.The AD1974 is designed for low EMI. This consideration is apparent in both the system and circuit design architectures. By using the on-board phase-locked loop (PLL) to derive the master clock from the LR clock or from an external crystal, the AD1974 eliminates the need for a separate high frequency master clock and can also be used with a suppressed bit clock. The ADCs are designed using the latest continuous time architectures from Analog Devices to further minimize EMI. By using 3.3 V supplies, power consumption is minimized, further reducing emissions.APPLICATIONS Automotive audio systems Home Theater Systems Set-top boxes Digital audio effects processors

The AD5231 is a nonvolatile memory, digitally controlled potentiometer with 1024-step resolution. The device performs the same electronic adjustment function as a mechanical potentiometer with enhanced resolution, solid state reliability, and remote controllability. The AD5231 has versatile programming that uses a standard 3-wire serial interface for 16 modes of operation and adjustment, including scratchpad programming, memory storing and restoring, increment/decrement, ±6 dB/step log taper adjustment, wiper setting readback, and extra EEMEM for user-defined information, such as memory data for other components, look-up table, or system identification information.In scratchpad programming mode, a specific setting can be programmed directly to the RDAC register that sets the resistance between Terminals W–A and Terminals W–B. This setting can be stored into the EEMEM and is transferred automatically to the RDAC register during system power-on.The EEMEM content can be restored dynamically or through external PR strobing, and a WP function protects EEMEM contents. To simplify the programming, the linear-step increment or decrement commands can be used to move the RDAC wiper up or down, one step at a time. The ±6 dB step commands can be used to double or half the RDAC wiper setting.The AD5231 is available in a 16-lead TSSOP. The part is guaranteed to operate over the extended industrial temperature range of −40°C to +85°C.APPLICATIONS Mechanical potentiometer replacement Instrumentation: gain, offset adjustment Programmable voltage to current conversion Programmable filters, delays, time constants Programmable power supply Low resolution DAC replacement Sensor calibration
