概述

Description

The TLV320AIC1110PBS is a low‑power stereo audio CODEC from TI’s TLV320AIC1x family. It integrates a stereo ADC and DAC, a built‑in headphone driver, and mic bias/power management in a compact package. It supports differential analog inputs (mic/line) and both line‑out and headphone outputs, with a flexible digital audio interface (I2S/PCM/left-justified) and an I2C control port for register configuration. The device offers 24‑bit data paths, configurable input/output gains, pop/noise suppression, and programmable digital processing features, making it suitable for portable devices. Typical applications include headsets, portable recorders, USB audio adapters, and other compact audio peripherals. The PBS suffix denotes the specific TI package variant. For exact electrical specs, pinout, and the full register map, see the TLV320AIC1110 datasheet and TI product page.

Features

Here are typical features of the TLV320AIC1110PBS:
- 2‑channel stereo ADC and DAC with 24‑bit data path
- Supports standard audio sample rates up to 96 kHz
- Flexible digital interface: I2S, left-justified, right-justified, and PCM formats
- Integrated headphone driver for direct headset output
- Analog front end: mic bias and preamplifier for electret mics; selectable analog inputs
- Programmable analog gain and digital volume control
- Digital features: mute, de-emphasis, and routing options
- Power management: low-power operation with sleep/standby modes
- Bias generation and protection circuitry (ESD protection)
- Small Pb‑free package (PBS) suitable for portable applications
Note: exact pinout, supply ranges, and performance figures vary by package variant; consult the datasheet for precise specifications.

Package

Plastic TSSOP-20 package (TLV320AIC1110PBS is in a TSSOP-20 package).

Pinout

Pin count: 28 pins (VSSOP-28 package).
Function: TLV320AIC1110PBS is a stereo audio analog-to-digital converter (codec front-end) with an integrated microphone bias and programmable gain; provides digital audio output via I2S/PCM and is controllable via I2C/SPI.

Manufacturer

The TLV320AIC1110PBS is manufactured by Texas Instruments (TI). TI is an American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits, including audio ICs, microcontrollers, DSPs, and related technologies.
