PCM6xx0-Q1 Audio Analog-to-Digital Converters

Texas Instruments PCM6xx0-Q1 Audio Analog-to-Digital Converters (ADCs) are 4-channel (PCM6240-Q1, PCM6340-Q1) and 6-channel (PCM6260-Q1, PCM6360-Q1) high-performance audio analog-to-digital converters (ADCs). These devices support analog input signals up to 10VRMS. The PCM6xx0-Q1 support line and microphone inputs and allow for both single-ended and differential input configurations. These devices offer an integrated high-voltage, programmable microphone bias, and input diagnostic circuitry. This circuitry allows for direct connection to microphone-based automotive systems with full fault diagnostic capability for direct-coupled inputs. The PCM62x0-Q1 integrates an efficient boost converter to generate a high voltage microphone bias using an external, low-voltage, 3.3V supply. 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 integrates the programmable channel gain, digital volume control, a low-jitter phase-locked loop (PLL), and a programmable high-pass filter (HPF). These also include biquad filters, low-latency filter modes, and allows for sample rates up to 768kHz. The Texas Instruments PCM6xx0-Q1 supports 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, 3.3V supply operation, make the PCM6xx0-Q1 family an excellent choice for space-constrained automotive systems.
