14-BIT, 1/3/8 MSPS DSP COMPATIBLE ANALOG-TO-DIGITAL CONVERTERS
WITH INTERNAL REFERENCE AND PGA
SLAS248 – DECEMBER 1999
description
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 µP
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.
