This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
DESCRIPTION (CONTINUED)
Combined with the advanced PowerTune technology, the device can cover operations from 8kHz mono voice
playback to stereo 192kHz DAC playback, making it ideal for portable battery-powered audio and telephony
applications.
The record path of the TLV320AIC3253 consists of a stereo digital microphone PDM interface (not available
when using SPI control interface) typically used at 64Fs or 128Fs.
The playback path offers signal processing blocks for filtering and effects, true differential output signal, flexible
mixing of DAC and analog input signals as well as programmable volume controls. The TLV320AIC3253
contains two high-power output drivers which can be configured in multiple ways, including stereo, and mono
BTL. The integrated PowerTune technology allows the device to be tuned to just the right power-performance
trade-off. Mobile applications frequently have multiple use cases requiring very low-power operation while being
used in a mobile environment. When used in a docked environment power consumption typically is less of a
concern while lowest possible noise is important. With PowerTune the TLV320AIC3253 can address both cases.
The voltage supply range for the TLV320AIC3253 for analog is 1.5V–1.95V, and for digital it is 1.26V–1.95V. To
ease system-level design, a low-dropout regulator (LDO) is integrated to generate the appropriate analog supply
from input voltages ranging from 1.8V to 3.6V. Digital I/O voltages are supported in the range of 1.1V–3.6V.
The required internal clock of the TLV320AIC3253 can be derived from multiple sources, including the MCLK pin,
the BCLK pin, the GPIO pin or the output of the internal PLL, where the input to the PLL again can be derived
from the MCLK pin, the BCLK or GPIO pins. Although using the internal, fractional PLL ensures the availability of
a suitable clock signal, it is not recommended for the lowest power settings. The PLL is highly programmable and
can accept available input clocks in the range of 512kHz to 50MHz.
The device is available in the 2.7mm × 2.7mm WCSP or the 4mm × 4mm QFN package.
