INPUT VOLUME CONTROL
AUDIO TAPER GAIN VALUES
www.ti.com....................................................................................................................................................................................................... SLOS544 – JULY 2008
The TPA2050D4 has two independent volume controls: One for the STEREO1 input pair (LIN_1 and RIN_1), and
one for the STEREO2 input pair (LIN_2 and RIN_2). Each has 5-bit (32-step) resolution and are audio tapered;
gain step changes are smaller at higher gain settings. The volume control range is –60 dB to +12 dB.
The Stereo Input 1 volume control byte is located at Register 5, Bits 4–0. The Stereo Input 2 volume control byte
is at Register 6, Bits 4–0. Gain matching between the left and right channels for STEREO1 and STEREO2 is
within 0.1 dB. In differential input mode, the Stereo Input 1 byte (Register 5) controls left and right channel gain.
The input impedance to the TPA2050D4 decreases as channel gain increases. See the Operating
Characteristics section for specifications. Values listed in Audio Taper Gain Values table are nominal values.
