It integrates, into an extremely compact flip-chip package, an audio amplifier, a speaker driver, and a headset driver. s b O t c u d o r P e The Audio Power Amplifier can deliver 1.1 W (typ.) of continuous RMS output power into an 8 Ω speaker with a 1% THD+N value. To the headset driver, the amplifier can deliver 85 mW (typ.) per channel of continuous average power into stereo 32 Ω bridged-tied load with 0.5% THD+N @ 5 V. Pin Out (top view) t e l o s b O This device features a 32-step digital volume control and 8 different output selections. The digital volume and output modes are controlled through a three-digit SPI interface bus.

It blocks the DC voltage at, and couples the input signal to the amplifier’s input terminals. Cin also creates a highpass filter with the internal input impedance Zin at Fc = 1 / (2π x Zin x Cin). Cs This is the Supply Bypass capacitor. It provides power supply filtering. CB This is the Bypass pin capacitor. It provides half-supply filtering. SPI Bus Interface 2 TS4855 SPI BUS INTERFACE 2.1 Pin Descriptions Pin Functional Description DATA This is the serial data input pin CLK This is the clock input pin ENB This is the SPI enable pin active at high level 2.2 SPI Operation Description The serial data bits are organized into a field containing 8 bits of data as shown in Table 1. The DATA 0 to DATA 2 bits determine the output mode of the TS4855 as shown in Table 2. The DATA 3 to DATA 7 bits determine the gain level setting as illustrated by Table 3. For each SPI transfer, the data bits are written to the DATA pin with the least significant bit (LSB) first. All serial data are sampled at the rising edge of the CLK signal. Once all the data bits have been sampled, ENB transitions from logic-high to logic low to complete the SPI sequence. All 8 bits must be received before any data latch can occur. Any excess CLK and DATA transitions will be ignored after the height rising clock edge has occurred. For any data sequence longer than 8 bits, only the Output Mode # DATA u d o r P e LSB DATA 0 MSB Mode 1 DATA 1 Mode 2 DATA 2 Mode 3 DATA 3 gain 1 DATA 4 gain 2 DATA 5 gain 3 DATA 6 gain 4 DATA 7 gain 5 t e l o bs MODES Table 2: Output Mode Selection DATA 1 DATA 0 SPKRout Rout Lout 0 0 0 SD SD SD 0 0 1 +12dBxPIHF SD SD 2 0 1 0 MUTE G1xPHS G1xPHS 3 0 1 1 +12dBxPIHF G1xPHS G1xPHS 4 1 0 0 MUTE G2xRin G2xLin 5 1 0 1 +12dBxPIHF G2xRin G2xLin 6 1 1 0 MUTE G1xPHS+ G2xRin G1xPHS+ G2xLin 7 1 1 1 +12dBxPIHF G1xPHS+ G2xRin G1xPHS+ G2xLin t e l o 0 bs 1 O P e ro ) s ( ct Table 1: Bit Allocation O ) t(s c u d first 8 bits will get loaded into the shift register and the rest of the bits will be disregarded.
