7 Application and Implementation

implementation to confirm system functionality.

7.1 Typical Application

Some applications require differential signals. Figure 7-1 shows a simple circuit to convert a single-ended input

of 2V to 10V into differential output of ±8V on a single 15V supply. The output range is intentionally limited

to maximize linearity. The circuit is composed of two amplifiers. One amplifier acts as a buffer and creates a

voltage, VOUT+. The second amplifier inverts the input and adds a reference voltage to generate VOUT–. Both

VOUT+ and VOUT– range from 2V to 10V. The difference, VDIFF, is the difference between VOUT+ and VOUT–.
