DESCRIPTION

NO.

NAME

PDMDIN2_GPI2

Analog output/digital input

Digital Input 2. MICBIAS output or general-purpose digital input 2 (multipurpose functions

such as digital microphones data, MICBIAS, PLL input clock source, and so forth). If used

as MICBIAS output, then connect a 1 µF to analog ground (AVSS)

VSS

Ground supply

Device ground internally shorted to thermal pad. Short this package corner pin directly to

the board ground plane. See the package drawing at the end of this document for corner

pin dimensions.

Thermal Pad

(VSS)

Ground supply

Thermal pad is shorted to the internal device ground. Short the thermal pad directly to the

board ground plane.

(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress

ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under

Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device

reliability.

6.2 ESD Ratings

VALUE

UNIT

V(ESD)

Electrostatic discharge

Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1)

±2000

Charged-device model (CDM), per JEDEC specification JESD22-C101(2)

±500

(1)

JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

(2)

JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
