Chapter 1 Introduction and Description This chapter provides a description of the THS3062EVM dual high-speed operational amplifier along with a schematic diagram. 1.1 Evaluation Schematic As delivered, the EVM has a fully functional example circuit, requiring added power supplies, a signal source, and a monitoring instrument. The default schematic diagram is provided in Figure 1-1.

Evaluation Schematic The noninverting gain of the EVM channel 1 amplifier, when using the default configuration, is affected by the same slight gain error plus the gain error im- posed by the inverting input termination resistor, R2. The following equation shows the gain for this situation: R4 ø...

Chapter 2 Using the THS3062EVM This chapter shows how to connect the THS3062EVM to test equipment. It is recommended that the user connect the EVM as described in this chapter to avoid damage to the EVM or the THS3062 installed on the board. Figure 2.1 shows how to connect power supplies, a 50-Ω...
Chapter 3 THS3062EVM Applications Example applications are presented in this chapter. These applications demonstrate the most popular circuits to the user, but many other circuits can be constructed. The user is encouraged to experiment with different circuits, exploring new and creative design techniques.
Noninverting Gain Stage 3.2 Noninverting Gain Stage For a noninverting stage in EVM channel 1, the EVM can be modified to eliminate the gain error imposed by R2 by replacing R2 with a 0-Ω resistor. This is shown in Figure 3-2. R4 has been removed as shown in the inverting gain stage example above.
Chapter 4 EVM Hardware Description This chapter describes the EVM hardware. It includes the EVM parts list, component placement diagram, and printed-circuit board layout. Table 4-1.
