Operation
(PCB) area in most applications. This device operates
from 2.5 V to 5.5 V, drawing only 1.7 mA of quiescent
– Fully Differential Design Reduces RF
supply current. The TPA6203A1 is available in the
Rectification
space-saving 2 mm x 2 mm MicroStar Junior™ BGA
– Improved CMRR Eliminates Two Input
package, and the space saving 3 mm x 3 mm QFN
Coupling Capacitors
(DRB) package.
– C(BYPASS) Is Optional Due to Fully Differential
Features like 85-dB PSRR from 90 Hz to 5 kHz,
Design and High PSRR
improved RF-rectification immunity, and small PCB
Avaliable in a 2 mm x 2 mm MicroStar
area makes the TPA6203A1 ideal for wireless
