14-bit, 1/3/8 MSPS DSP compatible analog-to-digital converters with internal reference and PGA
The THS1401, THS1403, and THS1408 are 14-bit, 1/3/8 MSPS, single supply analog-to-digital converters featuring an internal reference, differential inputs, and a programmable input gain. Implemented with a CMOS process, these devices are designed for use with 3.3-V systems and high-speed LLP compatible parallel interfaces, making them suitable for high-performance DSPs like the TMS320C6000 series.
