SSM2315 Overview
Key Specifications
Package: BGA
Mount Type: Surface Mount
Pins: 9
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 continues to provide high efficiency even at low output power
- It operates with 93% efficiency at 1.4 W into 8 Ω or 85% efficiency at 3 W into 3 Ω from a 5.0 V supply and has an SNR of >103 dB
- Spread-spectrum pulse density modulation is used to provide lower EMI-radiated emissions compared with other Class-D architectures
- The SSM2315 has a micropower shutdown mode with a typical shutdown current of 20 nA
