1.1 Evaluation Schematic
As delivered, the EVM has a fully functional example circuit—just add power
supplies, a signal source, and monitoring instrument. See Figure 1-1 for a
complete schematic diagram. EVM features include:
- Wide operating supply voltage range: ±5 V to ±15 V operation (see the
device data sheet)
- Inverting and noninverting gain configurations supported
- Single supply capability—R5 through R7 to provide internal or external
reference to the noninverting input
- Z1 through Z3 for ac coupling
- Nominal 50-Ω input impedance (R2 or R1). Termination can be configured
according to the application requirement.
- 1-kΩ load resistor R8. 1-kΩ is the standard data sheet load impedance.
- Footprints for a series resistor (Z3) or an A/D compensation network (Z3
and Z9)
- T-network in the feedback path can also be used to implement
transimpedance networks
- Power supply ripple rejection capacitors (C3 and C6)
- Decoupling capacitors (C4, C5, C7, C8, C9, C10)
- Test point for connection of a high impedance scope probe to op amp
output (TP3)
- Convenient GND test points (TP1 and TP2)
- PowerPAD heatsinking capability
- A good example of high-speed amplifier PCB design and layout
