Description
General part information
PCM1841-Q1 Series
The PCM1841-Q1 is a high-performance, Burr-Brown™ audio analog-to-digital converter (ADC) that supports simultaneous sampling of up to four analog channels. The device supports differential line and microphone inputs with a 2VRMS full-scale signal. The device integrates microphone bias voltage, a phase-locked loop (PLL), a DC removal high-pass filter (HPF), and supports sample rates up to 192kHz. The device supports time-division multiplexing (TDM), I2S, or left-justified (LJ) audio formats, selectable with the hardware pin level. Additionally, the PCM1841-Q1 supports controller and target mode selection for the audio bus interface operation. These integrated high-performance features, along with the ability to be powered from a single supply of 3.3V, make the device an excellent choice for cost-sensitive, space-constrained audio systems in far-field microphone recording applications.
The PCM1841-Q1 is specified from –40°C to +125°C and is offered in a 24-pin VQFN package.
