The TPA6020A2 is a 2.8-W stereo bridge-tied load
THD = 10% (Typical)
(BTL) amplifier designed to drive stereo speakers
with at least 3-
impedance. The device operates
Very Low Crosstalk:
from 2.5 V to 5.5 V, drawing only 8 mA of quiescent
– -100 dB Typical at 5 V, 3
supply current. The feedback resistors are internal,
2.5-V to 5.5-V Operating Range
allowing the gain to be set with only two input
resistors per channel. The amplifier's fully differential
Low Supply Current:
architecture performs with -80 dB of power supply
– 8 mA Typical at 5 V
rejection from 20 Hz to 2 kHz, improved RF rectifi-
– Shutdown Current: 80-nA Typical
cation immunity, small PCB area, and a fast startup
time with minimal pop, making the TPA6020A2 ideal
Fast Startup (27 ms) With Minimal Pop
for notebook PC applications.
