High Efficiency, Ground-Referenced Class-G Headphone Amplifier
The SSM2932 incorporates a gain control pin that selects a gain of 0 dB or 6 dB. The ground-referenced output scheme eliminates the need for large dc blocking capacitors, reducing system cost and board area. The Class-G amplifier is fine-tuned to maximize battery life, a critical task in portable applications. The device maximizes battery life by modulating the amplifier power supply rail to match the output demand without consuming excessive supply current, thus reducing power dissipation during typical audio playback.
The SSM2932 is specified over the industrial temperature range of −40°C to +85°C. It has output short-circuit protection as well as ESD protection to 8 kV (human body model). The SSM2932 is available in a 16-ball, 1.64 mm × 1.64 mm wafer level chip scale package (WLCSP).
