SSM2305 Overview
Key Specifications
Package: LFCSP EP
Mount Type: Surface Mount
Pins: 8
Max Voltage (typical range): 5.5 V
Key Features
- Filterless Class-D amplifier with Σ-Δ modulation No sync necessary when using multiple Class-D amplifiers from Analog Devices, Inc
- The modulation provides high efficiency even at low output power
- The SSM2305 operates with 90% efficiency at 1.3 W into 8 Ω or 83% efficiency at 2.2 W into 4 Ω from a 5.0 V supply and has an SNR of >98 dB
- Spread-spectrum pulse density modulation is used to provide lower EMI-radiated emissions compared with other Class-D architectures
- The SSM2305 has a micropower shutdown mode with a maximum shutdown current of 30 nA
