AN-1606 551012875, 551012922 Universal Op Amp
Evaluation Boards (SOT-23 and SC-70)

Overview
The 551012875 and 551012922 Universal Evaluation Boards are designed to aid in the evaluation and
testing of Texas Instruments low voltage/low power and some precision operational amplifiers. These
boards will accommodate op amps that are assembled in a 6-Pin or 5-Pin SOT-23 and SC-70 package,
regardless of the pin orientation.
testing of Texas Instruments low voltage/low power and some precision operational amplifiers. These
boards will accommodate op amps that are assembled in a 6-Pin or 5-Pin SOT-23 and SC-70 package,
regardless of the pin orientation.
This board is designed to use one or two amplifiers. Many different circuits can be made such as inverting,
non-inverting, and differential-IN-differential-OUT amplifiers and low-pass, high-pass, band-pass, band-
reject, or notch second-order filters. The amplifiers can be powered with single or dual supplies. These
circuits can be configured without any modifications to the board; all that is necessary is to select the
correct resistors and capacitors. The other optional components can be left open or shorted depending on
the configuration desired.

These universal evaluation boards are designed as two-layer boards; the top side of each is designed for
op amps with a pinout as shown in

The bottom side of each board is designed for op amps with the pinout shown in
. The board has
been manufactured with vias connecting the equivalent pins of the top and bottom amplifiers. For
example, Pin 1 of IC
example, Pin 1 of IC
1A
is connected to Pin 3 of IC
2A
. Similarly all other equivalent pins of the top and
bottom amplifiers are connected. This allows for an efficient use of one board to test two amplifiers of
different package types while keeping the same components on the board; just make sure that only one
amplifier is soldered to the same pads.

Circuit performance of this evaluation board will be comparable to final production designs. Use this
evaluation board as a guide for general layout and a tool to aid in device testing and characterization.
