3 Description
The PCM6120-Q1 is a Burr-Brown™ highperformance,
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. 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 farfield
microphone recording applications.
The PCM6120-Q1 is specified from –40°C to +125°C,
and is offered in a 20-pin WQFN package.
