Analog Front End (AFE)

This Product Selection Guide contains information to help select products in the Analog Front End (AFE) category on DigiKey.com

An Analog Front-End (AFE) is a semiconductor device that is used for signal conditioning and is comprised of analog amplifiers, op-amps, filters, and integrated circuits. This configurable functional block is used to interface with a variety of sensors. The available resolution ranges from 8 up to 42 bits, with the number of channels ranging from 1 to 256.


SelectionCharacteristics

Number of Bits: Indicates data converter resolution; the width of the digital word used by a device to represent an analog quantity.

Number of Channels: Indicates the number of separate channels able to be manipulated by the device.

Power (Watts): The maximum continuous output power a device is designed to produce.

Voltage - Supply, Analog: Describes the permitted operating range of the supply voltage required for powering the analog portion of a mixed-signal device. Voltages outside this range may damage the device and other system components.

Voltage - Supply, Digital: Describes the permitted operating range of the supply voltage required for powering the digital portion of a mixed-signal device. Voltages outside this range may damage the device and 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.
