GENERAL DESCRIPTION

The EVAL-ADA4522-2ARMZ allows the evaluation of the

ADA4522-2, 8-lead, dual-channel, mini small outline package

(MSOP) operational amplifier (op amp). Both channels of the

ADA4522-2 in this evaluation board are configured in a

noninverting amplifier with a gain of 101. The output has a low-

pass filter with a cutoff frequency of approximately 117 kHz

that minimizes the artifacts introduced by the 800 kHz

chopping frequency of the ADA4522-2.

The flexible design of the evaluation board allows the user to

create a multitude of configurations such as inverting and

noninverting amplifier, difference amplifier, and second-order

Sallen-Key filters. In addition, a combination of test points and

edge mounted Subminiature Version A (SMA) connectors are

used for the inputs and outputs for ease of use.

The evaluation board mainly consists of 0805 sized resistors

and capacitors to ensure easy installation by the user, besides

the bypass capacitors, C1 and C4. The 10 µF bypass capacitors

(C1 and C4) have a package size of 2220 to accommodate a

higher voltage rating because the ADA4522-2 has a maximum

supply of 55 V.

For full details on the ADA4522-2, see the ADA4522-1/

ADA4522-2/ADA4522-4 data sheet, which must be consulted

in conjunction with this user guide when using the EVAL-

ADA4522-2ARMZ.

EVALUATION BOARD QUICK START PROCEDURE

OVERVIEW

The following sections outline the basic prepopulated config-

uration of the EVAL-ADA4522-2ARMZ required to test

the basic functionality of the ADA4522-2. Both channels of the

ADA4522-2 are set up with the same configuration, but for this

section, only Channel A is discussed.

POWER SUPPLY CONSIDERATION

The terminal turrets labeled VS+, VS−, and GND are used to

power up the EVAL-ADA4522-2ARMZ. Make sure to always

connect the proper polarity to the evaluation board. A Zener diode

is installed to protect the evaluation board in case of power supply

reversal. Proper supply levels must be strictly followed, with a

range of 5 V to 55 V for single-supply operation and ±2.5 V to

±27.5 V for dual-supply operation. The evaluation board also

comes with a preinstalled decoupling capacitor with a value of

10 µF and 0.1 µF.

INITIAL BOARD CONFIGURATION

The following steps test the basic functionality of the preinstalled

circuit (noninverting amplifier, with a gain of 101) of the

EVAL-ADA4522-2ARMZ:

1. Before connecting anything to the evaluation board, first

ensure that the power supply and signal generator are

powered down.

2. Use the three banana jack to grabber cables to connect the

terminal turrets labeled VS−, GND, and VS+ to the

negative, ground, and positive supply, respectively.

3. Using an SMA to Bayonet Neill-Concelman (BNC) male

cable, connect the output of the signal generator to the

SMA on the evaluation board labeled INA+.

4. Using another SMA to BNC male cable, connect the SMA

output of the channel labeled OUTA to the oscilloscope.

5. For testing Channel B, repeat Step 3 and Step 4 and utilize

the SMA labeled INB+ and OUTB.

USING THE EVALUATION BOARD FOR TESTING

When the procedure in the Initial Board Configuration section

is completed, implement the following procedures and verify

the expected output:

1. Set the power levels to +15 V for the positive supply rail,

and −15 V for the negative supply rail.

2. Select a sine wave output for the signal generator. The

frequency is 1 kHz with a magnitude of 40 mV p-p. The

offset is at 0 V. Use a high-Z configuration for the output

of the signal generator.

3. Set the input or the termination of the oscilloscope at

1 MΩ. The parameters on the oscilloscope that must be

measured or observed are frequency and peak-to-peak

voltage.

4. After setting up all the equipment, turn on the power

supply first. Ensure that the current consumption is

between 1 mA and 3 mA and must not exceed 5 mA.

5. After turning on the supply and verifying the voltage and

current levels, turn on the signal generator. Ensure that the

signal generator is displaying the correct output.

6. The oscilloscope displays the output waveform. Because

the evaluation board is configured in a noninverting

amplifier with a gain of 101, the output is a sine wave with

a frequency of 1 kHz and a peak-to-peak voltage of

approximately 4.04 V.
