•Button Press DetectionIntegrated Power Supplies:– Negative Charge Pump for Capless HeadphoneDriver– Two Low Dropout Voltage Regulators (LDOs)for High Power Supply Rejection Ratio (PSRR)I2C Control
•
• Thermal Protection:– Host Interrupt
• Power Supplies:– Analog: 2.1 V– Digital I/O: 1.8 V– Battery: 2.3 to 5.5 V
• Package 6-mm × 6-mm 120-Pin PBGA
• Handheld DevicesThe TWL6040 device is an audio coder/decoder (codec) with a high level of integration providing analogaudio codec functions for portable applications, as shown in Figure 1-1. The device contains multipleaudio analog inputs and outputs, as well as microphone biases and accessory detection. The device isconnected to the OMAP™ 4 host processorthrough a proprietary PDM interface for audio datacommunication enabling partitioning with optimized power consumption and performance. Multichannelaudio data is multiplexed to a single wire for downlink (PDML) and uplink (PDMUL).The OMAP4 device provides the TWL6040 device with five PDM audio-input channels (DL0–DL4).Channels DL0–DL3 are connected to four parallel DAC channels multiplexed to stereo headphone (HSL,HSR), stereo speaker (HFL, HFR), and earpiece (EAR) or stereo line outputs (AUXL, AUXR).The stereo headphone path has a low-power (LP) mode operating from a 32-kHz sleep clock to enablemore than 100 hours of MP3 playback time. Very-high dynamic range of 104 dBA is achieved when usingthe system clock input and DAC path high-performance (HP) mode. Class-AB headphone drivers providea 1-Vrms capability output and are ground centered for capless connection to a headphone, thus enablingsystem size and cost reduction. The earpiece driver is a differential class-AB driver with 2 Vrms capabilityto a typical 32-Ω load or 1.4 Vrms to a typical 16-Ω load.
