This Product Selection Guide contains information to help select products in the Digital to Analog Converters (DAC) category on DigiKey.com
Digital-to-analog converters (DAC, D/A, D2A, or D-to-A) convert a digital signal into an analog buffered or unbuffered voltage or current. The suitability of a DACs architecture for a particular application is determined by resolution and sampling frequency. DACs are commonly used in music players to convert digital data streams into analog audio signals. They are also used in televisions and mobile phones to convert digital video data into analog video signals which connect to the screen drivers to display monochrome or color images.
SelectionCharacteristics
DigiKey Programmable: For verified products, DigiKey can program/flash your compiled code or configuration variables prior to shipping. For unverified products, please inquire with ProgCent.Techs@digikey.com.
Number of Bits: Indicates data converter resolution; the width of the digital word used by a device to represent an analog quantity.
Number of D/A Converters: Number of conversion devices inside the body of the item.
Settling Time: Characterizes the delay between a change in digital input code and the analog output approaching its final resulting value. Subject to manufacturer-defined test conditions.
Output Type: Describes how the device outputs the analog signal from the conversion.
Differential Output: Indicates if device outputs are presented as a difference between two output signals, as opposed to a single signal relative to a common reference.
Data Interface: Describes the format of how the device is communicated to.
Reference Type: Indicates the source of the analog reference voltage used by a device for performing data conversion.
Voltage - Supply, Analog: Describes the permitted operating range of the supply voltage required for powering the analog portion of a mixed-signal device.
Voltage - Supply, Digital: Describes the permitted operating range of the supply voltage required for powering the digital portion of a mixed-signal device.
INL/DNL (LSB): Integral/Differential NonLinearity: measures of deviation from an ideal straight-line transfer function over all input codes/between adjacent input codes.
Architecture: Indicates the basic technique used by a device for converting between analog and digital domains, which has general implications for device performance and application suitability.
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.
Package / Case: Describes the footprint and type of body the item has based on a general standard.
Supplier Device Package: Describes the footprint and type of body the item has based on what the manufacturer names it.
Mounting Type: Indicates how the device is attached.
