Cirrus Logic has introduced a new IC for smartphones and mobile applications: the CS42L73 smart audio codec focuses on lowering system power, improving battery life without compromising on audio performance!
The functionality and performance of the CS5484, CS5480 and the CS5490 energy measurement ICs can all be evaluated with the CDB5484-U, CDB5480-U and CDB5490-U demonstration boards. These CDBs expedite a preliminary performance assessment. Shunt resistors, current transformers or Rogowski coils can be connected to the analog inputs, while intuitive GUI software provides easy and full access to the on-board CS5484/80/90 devices and MCU.

The CS4354 is a 24-bit, 192 kHz stereo audio digital/analog converter (DAC) with an on-chip 2VRMS line driver working from a single 5 V power supply. This DAC is a step up version of the CS4352 that requires a 9 to 12V power supply.
The PA85 is a 450 V power operational amplifier with a very high 1,000 V/µs slew rate targeted for high voltage applications including instrumentation, piezoelectric transducers, and electrostatic transducers and deflection. 
This MOSFET power amplifier also features a very high 300 kHz of power bandwidth and is designed for output currents up to 200 mA.
The CS35L00/L01/L03 are a family of low power digital audio amplifiers with Cirrus Logic’s proprietary hybrid Class D architecture, designed specifically for today’s mobile applications: laptops, notebooks, tablets, smartphones.
