Texas Instruments PCM1863DBT
- Part Number:
- PCM1863DBT
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3018259-PCM1863DBT
- Description:
- IC ADC 2CH 110DB I2C/SPI 30TSSOP
- Datasheet:
- PCM1863DBT
Description
The PCM186x family of audio front-end devices integrates many system-level functions that assist or replace some DSP functions. All these features are available using a single 3.3V power supply. An integrated bandgap voltage reference provides excellent PSRR, so that a dedicated analog 3.3V rail may not be required.
Features
Universal Analog Mic Input, 2.1VAMS Full Scale
8 Analog Inputs with MUX and PGA
Analog pre-mix function before PGA/MUX
Single Ended, Pseudo-Differential or Differential Inputs with Mic Bias
4x Digital Microphone Inputs
Up to 4 Mono ADC channels (PCM1865)
Hardware Control (PCM1861)
I²C or SPI Control (PCM1863/5)
H/W Programmable Gain Amplifier
Fixed Mic Pregain select: 20, 32dB (Analog)
S/W Programmable Gain Amplifier
Integrated High Performance Audio PLL
Single 3.3V Supply for Analog and Digital
Additional 1.8V Core and Interface for lower power consumption
Power Dissipation at 3.3V: <85mW (PCM1861/3), <145mW (PCM1865)
'Energysense' Audio Content Detector for auto system wakeup and sleep
Master or Slave Audio Interface
Mixer functionality:
Digital Mixer to mix ADC outputs and I²S synchronous inputs
Zero Crossing PGA Gain changes
Automatic PGA Clipping Suppression control
PCB-footprint compatibility across all 3 devices
Applications
Home Theater and TV
Automotive Head Units
Bluetooth Speaker
Microphone Array Processors
