FAN3852UC16X Description

Short technical summary and product information.

The FAN3852UC16X from ON Semiconductor is an integrated microphone pre-amplifier featuring a digital Pulse Density Modulation (PDM) output. It is optimized for mobile handset and notebook PC microphone applications, accepting input from Electret Condenser Microphones (ECM).

 

This device operates within a supply voltage range of 1.64V to 3.63V and functions across an industrial temperature range of -40°C to 85°C. Key electrical specifications include a typical supply current of 420µA, a low power sleep mode current of 1.5µA, and a power-down mode current below 20µA. It offers a signal-to-noise ratio (SNR) of 62 dB at 16 dB gain and a total harmonic distortion of 0.02%.

 

The FAN3852UC16X supports an input clock frequency range of 1 MHz to 4 MHz and features a standard 5-wire digital interface. It includes an integrated Low Drop-Out (LDO) regulator. The component is housed in a compact 6-ball, 0.400 mm pitch WLCSP package measuring 1.242 mm x 0.842 mm, suitable for surface mounting.

 

ESD protection is provided with 1.5 kV HBM on the MIC input and 8 kV HBM on other pins. Typical applications include mobile handsets, headset accessories, and personal computers requiring digital audio output from ECMs.
