SSM2306: This high efficiency, Class-D stereo audio amplifier is designed to maximize performance for portable stereo amplifier applications and is capable of delivering 2 W of continuous output power with less than 1% THD+N, driving a 4-Ω load from a 5.0-V supply. The SSM2306 has a micro-power shutdown mode with a typical shutdown current of 20 nA. The fully differential input of the SSM2306 provides excellent rejection of common-mode noise on the input. It has built-in thermal shutdown and output short-circuit protection and is available in a 16-lead, 3 mm × 3 mm lead frame chip scale package (LFCSP).

SSM2304: The SSM2304 Class-D stereo audio amplifier features a high efficiency, low noise modulation scheme designed to maximize performance of portable applications. It operates with 85% efficiency at 1.4 W into 8 Ω from a 5.0 V supply and has a signal-to-noise ratio (SNR) that is better than 98 dB. Also, PDM modulation is used to provide lower EMI-radiated emissions compared with other Class-D architectures.  Additionally, the architecture of the device allows it to achieve a very low level of pop and click minimizing voltage glitches at the output during turn-on and turn-off, thus reducing audible noise on activation and deactivation.

SSM2302: The SSM2302 is a fully integrated, high efficiency, Class-D stereo audio amplifier designed to maximize performance for mobile phone applications. The fully differential input provides excellent rejection of common-mode noise on the input and the architecture of the device allows it to achieve a very low level of pop and click. The typical application circuit requires a minimum of external components and operates from a single 2.5 V to 5.0 V supply. It is capable of delivering 1.4 W of continuous output power with less than 1% THD + N driving an 8 Ω load from a 5.0 V supply.

SSM2301: This fully integrated, high efficiency, Class-D audio amplifier is designed to maximize performance for mobile phone applications. The typical application circuit requires a minimum of external components and operates from a single 2.5 V to 5.0 V supply. It is capable of delivering 1.4 W of continuous output power with less than 1% THD + N driving an 8 Ω load from a 5.0 V supply with an 85% efficiency.

Analog Devices Low Noise Amplifiers available from Digi-Key

Designing a system to meet very low noise requirements can be very challenging.  To ensure system noise remains within the overall noise budget, it is crucial to reduce the preamp noise which is propagated and further amplified as the signal progresses through the system.  Additionally, reducing preamp noise increases signal-to-noise ratios and allows the conditioning of very low level signals for better signal integrity.

Digi-Key offers a broad range of low noise amplifiers from Analog Devices that will aid in meeting the challenges of the latest design requirements.  Choose from the wide variety of high-speed, precision, differential, instrumentation, and variable gain amplifiers to meet any system specification.
