Texas Instruments ADS1206 ADS1207 Data Sheet Manual
Summary
These high-performance, low-cost Synchronous Voltage-to-Frequency Converters (VFC) include models ADS1206 and ADS1207. Designed for medium-resolution measurements, these devices convert input voltage into stable, synchronous frequency signals using external clock references. The product specification manual details operational parameters, including robust power supply flexibility (3.0V to 5.5V), low power consumption, and high effective resolution up to 12 bits. Ideal for engineers developing industrial control systems, motor drives, instrumentation, and portable measurement equipment requiring reliable signal conversion.

Frequently Asked Questions
What is the operating temperature range for the ADS1206 and ADS1207?
Both devices operate within a temperature range of -40°C to +85°C.
How do I calculate resolution using the input clock frequency?
For ADS1206, 1MHz results in an effective 12-bit resolution over a 4ms period. For ADS1207, 4MHz results in the same result over a 2ms period.
What are the recommended supply voltage levels for these devices?
Low-voltage operation requires 3.0V to 3.6V, while high-voltage operation uses 4.5V to 5.5V.
Are there different packages available for purchasing?
The ADS1206 and ADS1207 are available in an 8-lead VSSOP package.
