description
The TPA0211 is a 2-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 4-Ω
impedance. The device is ideal for use in small wireless communicators, notebook PCs, PDAs, anyplace a
mono speaker and stereo head phones are required. From a 5-V supply , the TPA021 1 can delivery 2-W of power
into a 4-Ω speaker.
The gain of the input stage is set by the user-selected input resistor and a 50-kΩ internal feedback resistor
(A
= – RF/ RI). The power stage is internally configured with a gain of –1.25 V/V in SE mode, and –2.5 V/V in
V
BTL mode. Thus, the overall gain of the amplifier is 62.5 kΩ/ R
in SE mode and 125 kΩ/ RI in BTL mode. The
I
input terminals are high-impedance CMOS inputs, and can be used as summing nodes.
The TP A0211 is available in the 8-pin thermally-enhanced MSOP package (DGN) and operates over an ambient
temperature range of –40°C to 85°C.
