Description
This document describes the TSSOP−16 package Op
Amp evaluation board. It should be used in conjunction with
the appropriate data sheet which contains full technical
details on the device specification and operation. This
evaluation board is offered as a convenience for the
customers interested in performing their own engineering
characterization and performance assessment. The
evaluation board provides a 50 W controlled impedance
environment. The evaluation board is designed to facilitate
a quick evaluation of the device. The populated evaluation
board will have a gain of two in a non−inverting op amp
configuration.

Board Lay−up
The TSSOP−16 evaluation boards are implemented in
two layers (Figure 1, Evaluation Board Lay−up). The first
layer is the 1.0 oz copper ground plane, where a portion of
the ground plane is cut out to mount the device. The FR4
dielectric material is placed between the first and second
layer. The second layer contains the rest of the components
and primary signal traces.

Board Design (NCS2530DTBEVB/NCS2535DTBEVB)
The evaluation board was designed for non−inverting op
amp configuration (See Figure 2). The input contains
termination resistor (usually 50 W). The input can also be
monitored through J1, J4, and J7. The evaluation board has
versatile loading options for the op amp, depending on the
user’s preference, it can be configured as capacitive load,
series resistance load, parallel resistance load, etc.
