The MAX9718AEUB+ is a 1.4W differential audio power amplifier in 10 pin μMAX package. This mono speaker amplifier feature a low power shutdown mode and industry-leading click and pop suppression and consist of high output current audio amplifier configured as BTL amplifier. The differential input structure improves noise rejection and provides common mode rejection. Bridge tied load (BTL) architecture minimizes external component count while providing high quality, power audio amplification. Device is available as an adjustable gain amplifier. It is used in mobile phones and PDAs.
Supply voltage range is 2.7V to 5.5V
Operating temperature range from -40°C to 85°C
Single channel amplifier, very high -93dB PSRR at 217Hz
Internal fixed gain to reduce component count, adjustable gain option
1.4W into 4ohm at 1% THD+N (per channel)
Differential input
