open-in-new Find other High-speed ADCs (>10MSPS)


The THS1401, THS1403, and THS1408 are 14-bit, 1/3/8 MSPS, single supply analog-to-digital converters with an internal reference, differential inputs, programmable input gain, and an on-chip sample and hold amplifier.

Implemented with a CMOS process, the device has outstanding price/performance and power/speed ratios. The THS1401, THS1403, and THS1408 are designed for use with 3.3-V systems, and with a high-speed uP compatible parallel interface, making them the first choice for solutions based on high-performance DSPs like the TI TMS320C6000 series.

The THS1401, THS1403, and THS1408 are available in a TQFP-48 package in standard commercial and industrial temperature ranges. The THS1401, THS1403, and THS1408 are available in a PQFP-48 package in automotive temperature range, and the THS1408 is available in a PQFP-48 package in military temperature range.
