Ω, 5 V, 1% THDN)
The TPA2037D1 is a 3.2 W high efficiency filter-free
+6 dB Fixed Gain
class-D audio power amplifier (class-D amp) with
Integrated Image Reject Filter for DAC Noise
6 dB of fixed gain in a 1.21 mm x 1.16 mm wafer chip
Reduction
scale package (WCSP). The device requires only one
external component.
Low Output Noise of 20 mV
Low Quiescent Current of 1.5 mA
Features like 95% efficiency, 1.5 mA quiescent
current, 0.1 mA shutdown current, 81-dB PSRR,
Differential Input Impedance of 300 k
20 mV output noise, and improved RF immunity make
Auto-Recovering Short-Circuit Protection
the TPA2037D1 class-D amplifier ideal for cellular
Thermal-Overload Protection
handsets. A start-up time of 4 ms with no audible pop
makes
the
TPA2037D1
ideal
for
PDA
and
Filter-Free Mono Class-D Amp
smart-phone applications.
