Texas Instruments THS1401, THS1403, THS1408 Data Sheet
Summary
The THS140x series offers high-performance 14-bit Analog-to-Digital Converters (ADCs) with internal reference and Programmable Gain Amplifiers (PGA). These single-supply, differential converters operate at 1/3 or 8 MSPS and are designed for compatibility with advanced DSPs like the TI TMS320C6000. Ideal for applications in industrial control, instrumentation, and xDSL front ends requiring high speed and high resolution, this manual provides comprehensive details on functionality, packaging options (TQFP-48), and electrical specifications.

Frequently Asked Questions
What is the typical DNL for this ADC?
The Differential Nonlinearity (DNL) is typically ±0.6 LSB.
Which DSPs are these converters compatible with?
They are highly suitable for high-performance DSPs like the TI TMS320C6000 series due to their parallel interface and timing compatibility.
What operating voltage range do these devices use?
These converters are designed for 3.3-V systems, requiring a single supply of 3.3-V.
Is an external clock capacitor required?
Yes, the CLK pin requires a 0.1-mF capacitor connected to AGND, and REF+ requires a 0.1-mF capacitor to AGND.
