description

The TPA0243 is a 2-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 4-Ω

impedance. The mono signal is created by summing left and right inputs. The amplifier can be reconfigured

on-the-fly to drive two stereo single-ended (SE) signals into head phones. This makes the device ideal for use

in small notebook computers, PDAs, digital personal audio players, anyplace a mono speaker and stereo head

phones are required. From a 5-V supply, the TPA0243 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 = – R / R ). The power stage is internally configured with a gain of –1.25 V/V in SE mode, and –2.5 V/V in

BTL mode. Thus, the overall gain of the amplifier is 62.5 kΩ/ R in SE mode and 125 kΩ/ R in BTL mode. The

input terminals are high-impedance CMOS inputs, and can be used as summing nodes.

The TPA0243 is available in the 10-pin thermally-enhanced MSOP package (DGQ) and operates over an

ambient temperature range of –40°C to 85°C.
