Pin Description

N/A I Internal Digital Power. Internal digital power supply, typically

+1.8 V.

N/A I Analog Power. Power supply for the internal analog section.

N/A I Charge Pump Supply. Provides charge pump voltage to the

headphone Class H analog output circuit.

N/A I Battery supply. Provides voltage to the headphone Class H

circuit.

Internal Digital I/O Digital I/O

Connection Driver Receiver

Ground

GNDD

N/A I Digital and I/O Ground. Ground for the I/O and core logic. GNDA,

GNDCP, and GNDD must be connected to a common ground area

under the chip.

GNDA

N/A I Analog Ground. Ground reference for the internal analog section.

GNDA, GNDCP, and GNDD must be connected to a common

ground area under the chip.

GNDCP 19

N/A I Charge Pump Ground. Ground reference for the charge pump

section. GNDA, GNDCP, and GNDD must be connected to a

common ground area under the chip.

Charge Pump

VCP_FILT+ 21

E2 VCP/ I/O Inverting Charge Pump Filter Connection. Power supply from

VCP_FILTâ 18

VP 1

the inverting charge pump that provides the positive/negative rail

for the analog output. When operating in external VCP_FILT

mode, these pins can directly take in supply voltage.

âVA

VA O VA Negative Charge Pump Output. Negative charge pump

output for DAC rail. It is derived from VA.

FLYP_VA 10

VA O âVA Charge Pump Cap Positive/Negative Node. Positive/

FLYN_VA 11

negative nodes for the DAC negative charge pumpâs flying

capacitor.

FLYP_VCP 24

E1 VCP/ O âVCP Charge Pump Cap Positive Node. Positive node for the

VP 1

analog output negative charge pumpâs flying capacitor.

FLYC_VCP 23

F1 VCP/ O âVCP Charge Pump Cap Center Node. Center node for the

VP 1

analog output negative charge pumpâs flying capacitor.

FLYN_VCP 20

G1 VCP_ O âVCP Charge Pump Cap Negative Node. Negative node for the

FILTÂ±

analog output negative charge pumpâs flying capacitor.

1.The power supply is determined by ADPT_PWR setting (see Section 4.3.1). VP is used if ADPT_PWR = 001 (VP_LDO Mode) or when necessary for

ADPTPWR = 111 (Adapt-to-Signal Mode).
