DESCRIPTION

The THS1401, THS1403, and THS1408 are 14-bit, 1/3/8

MSPS, single supply analog-to-digital converters (ADCs)

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 such as

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 also available in a PQFP-48 package in

automotive temperature range, and the THS1408 is

available in a PQFP-48 package in military temperature

range.
