LMV321IDCK Typical Application

Some applications require differential signals. Figure 8-1 shows a simple circuit to convert a single-ended input of 0.5 to 2 V into differential output of ±1.5 V on a single 2.7-V 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 0.5 to 2 V. The difference, VDIFF, is the difference between VOUT+ and VOUT-. The LMV358 was used to build this circuit.
