TDA9935

TDA9935 Rev. 04 — 17 September 2007 www.DataSheet4U.com Dual 14-bit, up to 160 Msample/s, 2 × interpolating Digital-to-Analog Converter (DAC) Product data sheet 1. General description The TDA9935 is optimized to reduce architecture complexity and overall system cost. Thanks to its direct IF conversion capabilities, it leads dynamic performance in multi-carrier support. With an internal sampling rate up to 160 Msample/s, TDA9935 is an extremely competitive solution for WCDMA, CDMA2000 and GSM/EDGE transmitters, as well as high data rate radio services like WLL, LMDS and BWA. 2.
