3 Overview of PCM6260-Q1 Family

To accommodate the short- and long-term vision of OEMs and TIer1s in most cost-optimized and space-constrained manner, Texas Instrument’s developed a highly-integrated, package- and software- compatible multi-channel audio ADC family called PCM6xx0-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 and low-latency filters, multiple biquads per channel, and high-pass filters. PCM6xx0-Q1 family support 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. The different offerings of this audio ADC family are shown in Table 3-1.
