11 Layout

11.1 Layout Guidelines

The OPA835DBV, OPA836DBV EVM (SLOU314) must be used as a reference when designing the circuit board. Follow the EVM layout of the external components near to the amplifier, ground plane construction, and power routing as closely as possible. General guidelines are:

  1. Signal routing must be direct and as short as possible into an out of the operational amplifier.
  2. The feedback path must be short and direct avoiding vias if possible especially with G = +1.
  3. Ground or power planes must be removed from directly under the negative input and output pins of the amplifier.
  4. A series output resistor is recommended to be placed as near to the output pin as possible. See Figure 17 for recommended values given expected capacitive load of design.
  5. A 2.2-µF power-supply decoupling capacitor must be placed within 2 inches of the device and can be shared with other operational amplifiers. For spit supply, a capacitor is required for both supplies.
  6. A 0.1-µF power-supply decoupling capacitor must be placed as near to the power supply pins as possible. Preferably within 0.1 inch. For split supply, a capacitor is required for both supplies.
