This Product Selection Guide contains information to help select products in the ADCs/DACs - Special Purpose category on DigiKey.com
Products in this family are used for the conversion of information between analog and digital representations and are adapted for specific use cases or integrate additional features or functionality not commonly encountered in general-purpose data converters. Examples include devices that integrate low-noise amplifiers and variable gain stages for ultrasound or automotive radar applications, audio and video-focused products, devices that integrate functionality to indicate measured values on segmented displays, devices integrating galvanic isolation between input and output, and others.
SelectionCharacteristics
Type: Indicates the style and configuration of the device.
Number of Channels: Indicates the number of separate channels able to be manipulated by the device.
Resolution (Bits): The length of the digital word used by a device to represent a continuously variable physical quantity.
Sampling Rate (Per Second): The number of measurements per second the device is able to take.
Data Interface: Indication of which interface(s) or protocol(s) are used by the device to communicate with other components in the system.
Voltage Supply Source: A general description of how the device is nominally powered.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and/or other system components.
Mounting Type: Indicates how the device is attached.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the supplier device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
