TLV320ADC6120

SBASA92A – DECEMBER 2020 – REVISED JUNE 2021

TLV320ADC6120 2-Channel, 768-kHz, Burr-Brown^TMAudio ADC

1 Features

3 Description

•

Multichannel high-performance ADC:

– 2-channel analog microphones or line-in

– 4-channel digital PDM microphones

– Up to 2 analog and up to 2 digital microphone

channels

ADC line and microphone differential input

performance:

– Dynamic range (DR):

The TLV320ADC6120 is

Burr-Brown^™high-

performance, audio analog-to-digital converter (ADC)

that supports simultaneous sampling of up to two

analog channels or four digital channels for the

pulse density modulation (PDM) microphone input.

The device supports line and microphone inputs, and

allows for both single-ended and differential input

configurations. The device integrates programmable

channel gain, digital volume control, a programmable

microphone bias voltage, a phase-locked loop (PLL),

a programmable high-pass filter (HPF), biquad filters,

low-latency filter modes, and allows for sample

rates up to 768 kHz, and allows for sample rates

up to 192 kHz. The device supports time-division

multiplexing (TDM), I²S, or left-justified (LJ) audio

formats, and can be controlled with the I²C interface.

These integrated high-performance features, along

with the ability to be powered from a single-supply

of 3.3 V or 1.8 V, make the device an excellent

choice for space-constrained audio systems in far-

field microphone recording applications.
