概述

Description

PCM1863DBT is Texas Instruments’ two-channel, 24-bit delta-sigma analog-to-digital converter (ADC) with an integrated front-end for stereo audio capture. It converts two differential analog input signals into digital audio data over a standard digital interface.
Key features:
- Two differential analog inputs with an on-chip programmable gain amplifier (PGA)
- 24-bit delta-sigma ADC with a digital decimation filter
- Serial digital output formats (I2S, left-justified, PCM)
- Support for standard audio sample rates (typical up to 96 kHz)
- Low power, compact package (DBT variant)
Applications:
- USB/audio interfaces, portable recorders, conferencing systems, and embedded audio capture in consumer/professional devices
Note: DBT denotes a specific packaging variant of the PCM1863. It is an ADC (no DAC) intended for high-quality stereo audio capture with easy integration into embedded systems.

Package

PCM1863DBT is in a 16‑pin VSSOP package (VSSOP‑16), with the Tape‑and‑Reel option (suffix T).

Pinout

- Pin count: 28 pins (DBT package)
- Function: 24‑bit stereo analog-to-digital converter (A/D) with differential analog inputs and a digital audio interface (I2S/PCM).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is a global American semiconductor company that designs and manufactures analog and embedded processing integrated circuits used across consumer, automotive, industrial, and other markets.

Application

PCM1863DBT is a high-performance stereo ADC for portable and consumer audio. Common applications include voice/music capture in smartphones/tablets, handheld recorders, and USB audio interfaces; digital inputs to DACs in smart speakers, soundbars, and wireless headsets; conferencing equipment and telephony; and IoT audio devices, offering low-noise, high-resolution conversion in compact form factors.
