Symbol
Description
1
I
IN_R
Negative input of the second amplifier. It receives the audio input signal. Connected to the input
capicator Cin (NCP2809A) or the external Rin (NCP2809B).
2
I
SHUTDOWN
The device enters in shutdown mode when a a low level is applied on this pin.
3
I
BYPASS
Bypass capacitor pin which provides the common mode voltage (VP/2).
4
O
REF_I
Virtual ground amplifier feed back. This pin sets the stereo headset ground. In order to improve
crosstalk, this pin must be connected as close as possible to the ground connection of the headset
(ideally at the ground pin of the headset connector). When one uses bypassing capacitors, this pin
must be left unconnected.
5
I
IN_L
Negative input of the first amplifier. It receives the audio input signal. Connected to the input
capacitor Cin (NCP2809A) or the external Rin (NCP2809B).
6
O
OUT_L
Stereo headset amplifier analog output left. This pin will output the amplified analog signal and,
depending on the application, must be coupled with a capacitor or directly connected to the left
loudspeaker of the headset. This output is able to drive a 16 W load in a singleended configuration.
7
I
VP
Positive analog supply of the cell. Range: 2.2 V – 5.5 V
8
O
OUT_I
Virtual ground for stereo Headset common connection. This pin is directly connected to the
common connection of the headset when use of bypassing capacitor is not required. When one
uses bypassing capacitors, this pin must be left unconnected.
9
I
VM
Analog Ground
10
O
OUT_R
Stereo headset amplifier analog output right. This pin will output the amplified analog signal and,
depending on the application, must be coupled with a capacitor or directly connected to the right
loudspeaker of the headset. This output is able to drive a 16 W load in a singleended configuration.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Human Body Model, 100 pF discharged through a 1.5 kW resistor following specification JESD22/A114 8.0 kV can be applied on OUT_L,
OUT_R, REF_I and OUT_I outputs. For other pins, 2.0 kV is the specified voltage.
2. Machine Model, 200 pF discharged through all pins following specification JESD22/A115.
3. Maximum ratings per JEDEC standard JESD78.
*This device contains 752 active transistors and 1740 MOS gates.
