This Product Selection Guide contains information to help select products in the Op Amp Evaluation Boards category on DigiKey.com
Op Amp Evaluation boards are circuit boards populated with components and used to provide a working example of a specific op amp or device. The channels per IC can be single, dual, triple, quad, or octal, with amplifier types of audio, buffer, differential, instrumentation, and power to name a few.
SelectionCharacteristics
Channels per IC: Indicates the number of parallel instances of a similar function that are implemented within the focus device of an evaluation/development board.
Amplifier Type: Characterizes the intended function or defining design feature of the amplifier device features on an evaluation board.
Output Type: Indicates which output characteristics the focus device offers.
Slew Rate: Characterizes the maximum rate at which an amplifier can change its output voltage in response to a change in input. Measured under manufacturer-defined test conditions.
-3db Bandwidth: Characterizes the upper limit of an amplifier’s useful frequency response, indicating the frequency at which its gain has fallen by 3dB under specified test conditions. Commonly used instead of gain-bandwidth product for characterizing the speed of current-feedback amplifiers.
Current - Output / Channel: Typically this indicates the maximum current an output channel can provide.
Current - Supply (Main IC): This represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.
Voltage - Supply, Single/Dual (±): Indicates the permissible supply voltage range for a device. Devices listed with a range that doesn’t include a +/- term are “single supply” capable, which typically implies a common-mode input range that includes the most-negative supply rail.
Board Type: Indicates the extent to which a board has been populated.
Supplied Contents: Indicates items included with purchase.
Utilized IC / Part: Indicates the central integrated circuit the device is designed around.
