The TLC320AD50C/I and TLC320AD52 analog interface circuits (AICs) provide high-resolution A/D and D/A signal conversion using oversampling sigma-delta techniques. These 16-bit AICs can be used as an analog front end in modem applications, and also provide an ideal solution for business audio or motherboard audio applications. Additional applications include reduced-function modems for PDAs, point-of-sale terminals, and general DSP or MCU interface applications.

One of the main features of the ’AD50C/I is its master/slave capability with support for up to three slaves. The TLC320AD52 provides identical functionality to the ’AD50C, but supports only one slave in master/slave mode.
Other features of the ’AD50/52 AICs include internal 64X oversampling on the ADC and 256X oversampling on the DAC, as well as differential outputs that can drive a 600- differential load. Options for all the devices include selectable conversion rate, reset, power down, communications protocol, serial clock rate, gain control and system test mode.
The ’AD50I is available in 28-pin SOIC (DW) package and the ’AD50C/52 is available in 28-pin SOIC (DW) and 48-pin TQFP (PT) packages.
