1 Introduction to the PCM6260-Q1 Family

To accommodate the short- and long-term vision of OEMs and TIer1s in most cost-optimized and space-constrained manner, Texas Instruments developed a highly-integrated, package- and software-compatible, high-performance, multi-channel audio ADC family called PCM6260-Q1. These devices support microphone (analog and digital) and line inputs and integrate a programmable high-voltage microphone bias and input fault diagnostics. These devices provide a very flexible digital filtering scheme with linear phase, low latency and ultra-low latency filters, multiple programmable biquads per channel, and high-pass filters. The PCM6260-Q1 family supports a very flexible data output and control interface, allowing several devices to use the same output data and control interface bus. In addition, these devices have GPIOs, fine phase and gain calibration schemes, and a digital mixer and summer, to optimize the system performance to a whole new level. Figure 1-1 shows a functional block diagram of the PCM6260-Q1 device.

The PCM6260-Q1 device is one of the PCM6xx0-Q1 family that are available in two (PCM6020-Q1), four (PCM6240-Q1, PCM6340-Q1), six (PCM6260-Q1, PCM6360-Q1), and eight (PCM6480-Q1) channel package- and software-compatible options. Table 1-1 shows the different offerings of this audio ADC family.
