description
The TPA2000D1 is a 2-W mono bridge-tied-load
(BTL) class-D amplifier designed to drive a
speaker with at least 4-
impedance. The
amplifier uses TI’s third generation modulation
technique, which results in improved efficiency
and SNR. It also allows the device to be connected directly to the speaker without the use of the LC output filter
commonly associated with class-D amplifiers (this will result in EMI which must be shielded at the system level).
These features make the device ideal for use in devices where high-efficiency is needed to extend battery run
time.
The gain of the amplifier is controlled by two input terminals, GAIN1, and GAIN0. This allows the amplifier to
be configured for a gain of 6, 12, 18, and 23.5 dB. The differential input terminals are high-impedance CMOS
inputs, and can be used as summing nodes.
The class-D BTL amplifier includes depop circuitry to reduce the amount of turnon pop at power up, and when
cycling SHUTDOWN.
The TPA2000D1 is available in the 16-pin TSSOP package (PW) which is capable of driving 2-W continuous
output power level into a 4-
load. TPA2000D1 operates over an ambient temperature range of –40
°
C to 85
°
C.
