INPUT VOLUME CONTROL
AUDIO TAPER GAIN VALUES
SLOS607 – APRIL 2009 ..................................................................................................................................................................................................... www.ti.com
The TPA2054D4 has three independent volume controls: one for the Mono differential input, 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 –66 dB to +24 dB.
Total input-to-output gain is input gain plus the headphone or Class-D amplifier gain. The Class-D amplifier gain
is fixed at +6 dB. The headphone gain is programmable at +6 dB (default), 0 dB, –6 dB, and –14 dB. Headphone
gain is set via the I2C interface.
The Mono Input volume control byte is located at Register 4, Bits 4 – 0. 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 TPA2054D4 decreases as channel gain increases. See the Operating
Characteristics section for specifications. Values listed in Audio Taper Gain Values table are nominal values.
