Pin Description
TDFN PIN
NAME
FUNCTION
1
SDA
I2C Serial Data. Input/output for I2C data.
2
SCL
I2C Serial Clock. Input for I2C clock.
3, 4, 5
A0, A1, A2
Address-Select Inputs. Determines I2C address. Device address is 1010A2A1A0. (See the I2C Slave
Address and Address Pins section for more details.)
6WP
Write-Protect Input. Must be grounded to write to the registers. An internal pullup will lock the register
values if this pin is not connected.
7
GND
Ground Terminal
8, 11
L0, L1
Potentiometer Low Terminals. Voltages on these pins should remain between GND and VCC.
9, 12
V0, V1
Amplifier Outputs
10, 13
H0, H1
Potentiometer High Terminals. Voltages on these pins should remain between GND and VCC.
