Product Usage Instructions

Getting Started:

Software Installation:

Install the ADALM2000 driver and Scopy software from the provided resources.
Refer to the Wiki Tools for the quick start procedure and troubleshooting tips.

Hardware Integration:

Connect the ADALM2000 to your computer using a micro-USB cable.
Open the Scopy software on your computer.
In Scopy, click on Preferences icon and reset to default settings.
Click on the ADALM2000 icon, then click Connect to establish a connection.
Align and connect the EVAL-KW4502Z board with the ADALM2000 following the pinout guide.

Jumper Settings:
The jumper configuration on EVAL-KW4502Z can be adjusted for different output settings:

Jumper Cap – Analyzer (Default)
Jumper Cap – Zero-Drift
Jumper Cap – Low Noise
Jumper Cap – Low Power

General Description

The EVAL-KW4502Z is a demonstration board for evaluating the low-frequency noise of three general operational amplifiers (op amp): (1) low-power op amp, (2) low-noise, bipolar op amp, and (3) low-noise, zero-drift op amp.
The EVAL-KW4502Z uses ADA4510-2, which is a high precision, low offset voltage, low-noise, rail-to-rail input and output operational amplifier, as it can operate in low voltage supplies like ±5V that can be provided by the ADALM2000 Active Learning Module.
The EVAL-KW4502Z accommodates LT1782, ADA4077, and ADA4522 in a thin small outline transistor (TSOT), standard small outline package (SOIC), and mini small outline package (MSOP), respectively.
Full specifications on the LT1782, ADA4077, and ADA4522 are available on the Analog Devices, Inc. website.

Features

Enables Quick Measurement of Low-Frequency Noise (0.1Hz to 10Hz)
Evaluates Low-Power, Low-Noise, and Zero-Drift Amplifiers
Accommodates 5-Lead TSOT, 8-Lead SOIC, and 8-Lead MSOP Packages
Easy plugin into ADALM2000 Active Learning Module

Getting Started

Software Installation

The ADALM2000 driver and Scopy software are necessary to use the ADALM2000 device and control it through the computer.
The quick start procedure for starting the ADALM2000 can be found on the Wiki Tools. It also includes some common troubleshooting tips.

Hardware Integration

Plug in a micro-USB cable to the connectivity port as shown in Figure 3, connecting the laptop/computer to the ADALM2000.
Open the Scopy software to establish a connection between the laptop/computer and the ADALM2000.
As shown in Figure 4, click the Preferences icon and “Reset Scopy” to its default configuration.
As shown in Figure 5, click the ADALM2000 icon, then click the Connect button to begin connecting. The device is successfully connected when the Connect button is replaced with the Disconnect button.
Connect the EVAL-KW4502Z top side with the top side of the ADALM2000 aligning their pinouts as shown in Figure 6.

Jumper Settings
The EVAL-KW4502Z output is reconfigurable based on jumper configuration. By default, the jumper cap (see Figure 7) is set in the analyzer, but it can be set either to zero-drift or low noise or low power to measure their low- frequency noise.

Output
The ADALM2000 is a multifunction device that includes an oscilloscope among its capabilities. The oscilloscope is used to visualize and analyze the 0.1Hz to 10Hz of the chosen amplifier based on the jumper configuration. In the Oscilloscope tab, configure Channel 1 to set the time per division to 625ms/div and volts per division to 200mV/div. Click the Run button in the upper right to start the sweep of the oscilloscope and wait for the output to settle to a stable value. The filter requires approximately 1 minute to settle.
