EVAL-ADA4522-2ARMZ, Primary Side 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 lowpass 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 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 F 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 EVALADA4522-2ARMZ. PLEASE SEE THE LAST PAGE FOR AN IMPORTANT WARNING AND LEGAL TERMS AND CONDITIONS. Rev. 0 | Page 1 of 6 23126-002 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. Figure 2.

Both channels of the ADA4522-2 are set up with the same configuration, but for this section, only Channel A is discussed. When the procedure in the Initial Board Configuration section is completed, implement the following procedures and verify the expected output: POWER SUPPLY CONSIDERATION 2. 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 F and 0.1 F. 1. 3. 4. INITIAL BOARD CONFIGURATION 5. The following steps test the basic functionality of the preinstalled circuit (noninverting amplifier, with a gain of 101) of the EVAL-ADA4522-2ARMZ: 6. 1. 2. 3. 4. 5. Before connecting anything to the evaluation board, first ensure that the power supply and signal generator are powered down. 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. 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+. Using another SMA to BNC male cable, connect the SMA output of the channel labeled OUTA to the oscilloscope. For testing Channel B, repeat Step 3 and Step 4 and utilize the SMA labeled INB+ and OUTB. Rev. 0 | Page 3 of 6 Set the power levels to +15 V for the positive supply rail, and -15 V for the negative supply rail. 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. Set the input or the termination of the oscilloscope at 1 M. The parameters on the oscilloscope that must be measured or observed are frequency and peak-to-peak voltage. 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. 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. 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.
