1.1 Evaluation Modue Features
The THS6182EVM provides a platform for developing high-speed operational
amplifier application circuits. It contains the THS6182 high-speed dual
operational amplifier, a number of passive components, and various features
and footprints that enable the user to experiment with, test, and verify various
operational amplifier circuit implementations. The PC board measures 4.0 by
2.8 inches. THS6182 high-speed operational amplifier EVM features include:
- Active termination capability (R3 and R12)
- Snubber circuit (R1 and C1), for use with active termination
- Hooks for a recieve path signal (TP1 through TP4)
- Noninverting gain configuration for DSL
- High-pass filter (HPF) function for ADSL (C2 and R23)
- Short-loop length for the power supply differential high-frequency path
(C9)

1.3 EVM Default Configuration
As delivered, the EVM has a fully functional example circuit, requiring added
power supplies, a signal source, and monitoring instrument. See Figure 1−1
for the complete EVM schematic.
The default configuration has a differential gain of 2.22, as determined by R2,
R23, and R11 in combination with series matching resistors R6, R7, R15, and
R16, and a 50-Ω load on the outputs at J1 and J3.
Some components such as R20, R21, R24–R29, C3–C11, FB1, FB2, JP1,
JP2, J5–J7, and TP8–TP10, etc., are omitted on the application schematics
of Chapter 3 for clarity.
