16-bit sigma delta AIC

The TLC320AD50 16-bit analog interface circuit (AIC) uses an oversampling sigma delta technique to provide high-resolution signal conversion for business audio and modem applications.

Master/slave capability allows use in multiple-AIC applications such as voice-enabled modems, industrial process control, and noise cancellation/suppression. A 3-V interface and low power dissipation of only 120 mW make the device suitable for battery-operated equipment.

The AD50 provides a glueless interface via serial port to TMS320 and other industry-standard DSPs. The device offers the following options: selectable conversion rate, reset, power-down, communications protocol, serial clock rate, gain control and system test mode (digital and analog loopback test mode).
