The 4-channel PCM6x40-Q1 (PCM6240-Q1, PCM6340-Q1) and 6-channel PCM6x60-Q1 (PCM6260-Q1, PCM6360-Q1) are high-performance, audio analog-to-digital converters (ADCs) that support analog input signals up to 10 VRMS. The PCM6x40-Q1 and PCM6x60-Q1 (PCM6xx0-Q1) support line and microphone inputs, and allows for both single-ended and differential input configurations. These devices offer an integrated high-voltage, programmable microphone bias, and input diagnostic circuitry that allow direct connection to microphone-based automotive systems with full fault diagnostic capability for direct-coupled inputs. The PCM62x0-Q1 integrate an efficient boost converter to generate a high voltage microphone bias using an external, low-voltage, 3.3-V supply, whereas the PCM63x0-Q1 directly uses an external high-voltage supply (HVDD), which is a readily available supply in the system to generate the high-voltage, programmable microphone bias. The PCM6xx0-Q1 integrate the programable channel gain, digital volume control, a low-jitter 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 PCM6xx0-Q1 support time-division multiplexing (TDM), I2S, or left-justified (LJ) audio formats, and can be controlled with either the I2C or SPI interface. These integrated high-performance features, along with a single, 3.3-V supply operation, make the PCM6xx0-Q1 family an excellent choice for space-constrained automotive systems.
