Most common type of amplifier. Class G Amplifiers Designed to operate at low supply voltages for the majority of audio-signal levels, but are able to increase dynamic range temporarily when high signal levels are received. Class D Amplifiers A switching or PWM amplifier, the switches are either fully on or fully off, significantly reducing the power losses in the output devices. Efficiencies of 90-95% are possible. 2 April 2014 • 1623 Buckeye Dr. Milpitas, CA 95035 • 408 969 6600 • [email protected] • www.issi.com Class AB Audio Amplifiers IS31AP4833 All-in-one stereo amp with built-in headphone drivers Features Independent volume control for two channels Treble, bass and mute control Stereo input MUX I2C control for tone, volume, 3D and mux input selection • Software controlled shutdown • Auto detect headphone plug-in with click-and-pop suppression • 3D surround sound and tone control Output Level (dB) • • • • 36 Pin QFN Package 4x4 mm Frequency (Hz) Bass and Treble Response vs. Frequency April 2014 • 1623 Buckeye Dr. Milpitas, CA 95035 • 408 969 6600 • [email protected] • www.issi.com 3 Headphone Audio Amplifiers IS31AP4913 High quality stereo headphone driver with 3D & Bass Enhancement Features •No output DC-blocking capacitors •3D Surround and Bass enhancement digitally enabled •Pulse Count Control serial interface •Ultra-low 8μV output noise •High SNR (102db) •Click-and-pop suppression •Built-in Charge pump converter for low power ISAP2031 Output Voltage (V) 20 Pin QFN Package 3x3mm Frequency (Hz) Low Output Noise 4 April 2014 • 1623 Buckeye Dr. Milpitas, CA 95035 • 408 969 6600 • [email protected] • www.issi.com Class G Audio Amplifiers IS31AP2031 High Power, Ultra-low EMI Class-G Amplifier with AGC Features •2.0W into an 8Ώ load from a 4.2V supply (10% THD+N) •Fully differential amplifier for noise cancellation •Highly efficient Class G with integrated charge pump •Cost, space and power efficient than boost converter alternatives •The operating mode and AGC function are controlled by Pulse Count ISAP2031 Control (PCC wire) serial interface •4 gain levels: 12dB, 16dB, 24dB, 27.5dB THD+N(%) 20 Pin QFN Package 3x3mm Extended Battery Life!
