Specifications
- TypeParameter
- Factory Lead Time18 Weeks
- Mounting Type
The "Mounting Type" in electronic components refers to the method used to attach or connect a component to a circuit board or other substrate, such as through-hole, surface-mount, or panel mount.
Surface Mount - Package / Case
refers to the protective housing that encases an electronic component, providing mechanical support, electrical connections, and thermal management.
16-TSSOP (0.173, 4.40mm Width) - Operating Temperature
The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.
-40°C~125°C - Packaging
Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.
Tape & Reel (TR) - Part Status
Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.
Active - Moisture Sensitivity Level (MSL)
Moisture Sensitivity Level (MSL) is a standardized rating that indicates the susceptibility of electronic components, particularly semiconductors, to moisture-induced damage during storage and the soldering process, defining the allowable exposure time to ambient conditions before they require special handling or baking to prevent failures
1 (Unlimited) - Configuration
The parameter "Configuration" in electronic components refers to the specific arrangement or setup of the components within a circuit or system. It encompasses how individual elements are interconnected and their physical layout. Configuration can affect the functionality, performance, and efficiency of the electronic system, and may influence factors such as signal flow, impedance, and power distribution. Understanding the configuration is essential for design, troubleshooting, and optimizing electronic devices.
MUX-S/H-ADC - Number of Bits12
- Input Type
Input type in electronic components refers to the classification of the signal or data that a component can accept for processing or conversion. It indicates whether the input is analog, digital, or a specific format such as TTL or CMOS. Understanding input type is crucial for ensuring compatibility between different electronic devices and circuits, as it determines how signals are interpreted and interacted with.
Single Ended - Architecture
In electronic components, the parameter "Architecture" refers to the overall design and structure of the component. It encompasses the arrangement of internal components, the layout of circuitry, and the physical form of the component. The architecture of an electronic component plays a crucial role in determining its functionality, performance, and compatibility with other components in a system. Different architectures can result in variations in power consumption, speed, size, and other key characteristics of the component. Designers often consider the architecture of electronic components carefully to ensure optimal performance and integration within a larger system.
SAR - Number of Inputs8
- Data Interface
A Data Interface in EDQ is a template of a set of attributes representing a given entity, used to create processes that read from, or write to, interfaces rather than directly from or to sources or targets of data.
SPI - Voltage - Supply, Analog
Voltage - Supply, Analog is a parameter in electronic components that specifies the range of voltage levels required to power the analog circuitry within the component. This parameter indicates the minimum and maximum voltage levels that the component can accept for proper operation of its analog functions. It is crucial to ensure that the voltage supplied to the component falls within this specified range to prevent damage and ensure optimal performance. Understanding and adhering to the "Voltage - Supply, Analog" parameter is essential for the proper functioning of analog circuits in electronic components.
2.7V~3.6V - Voltage - Supply, Digital
Voltage - Supply, Digital is a parameter that specifies the voltage level required to power the digital circuitry within an electronic component, such as an integrated circuit or a microcontroller. This parameter is crucial for ensuring proper operation of the digital components, as supplying the correct voltage level is essential for reliable performance. The specified voltage range typically includes both minimum and maximum values within which the component can operate safely and efficiently. It is important to adhere to the recommended voltage supply range to prevent damage to the component and to maintain the integrity of the digital signals being processed.
2.7V~3.6V - Sampling Rate (Per Second)
The sampling rate (per second) in electronic components refers to the frequency at which an analog signal is measured or sampled to convert it into a digital signal. It is typically expressed in Hertz (Hz) and indicates how many times per second the analog signal is sampled. A higher sampling rate allows for better representation of the original signal, capturing more detail and reducing distortion during the conversion process. In audio applications, for example, common sampling rates include 44.1 kHz for CD-quality audio and 48 kHz for video production.
1M - Number of A/D Converters1
- Ratio - S/H:ADC
The parameter "Ratio - S/H:ADC" in electronic components refers to the ratio between the sample and hold (S/H) circuit and the analog-to-digital converter (ADC) in a system. The sample and hold circuit is responsible for capturing and holding the input signal at a specific moment in time, while the ADC converts this analog signal into a digital format for processing. The ratio between the S/H and ADC components is important as it determines the accuracy and speed of the analog-to-digital conversion process. A higher ratio typically indicates a more precise and efficient conversion process, leading to better overall performance of the electronic system. Engineers often consider this parameter when designing and optimizing electronic circuits to ensure reliable and high-quality signal processing.
