THS1408-EP
14-BIT, 3/8 MSPS DSP-COMPATIBLE ANALOG-TO-DIGITAL CONVERTER
WITH INTERNAL REFERENCE AND PGA
SGLS129B − JULY 2002 − REVISED FEBRUARY 2010
description
The THS1408 is a 14-bit, 3/8-MSPS single-supply analog-to-digital converter (ADC), 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
THS1408 is designed for use with 3.3-V systems, and with a high-speed μP-compatible parallel interface, making
it the first choice for solutions based on high-performance DSPs like the TI TMS320C6000 series.
