GENERAL DESCRIPTION
The TDA9901 is a wideband, low noise amplifier with
differential inputs and outputs. The TDA9901 incorporates
an AGC function with digital control. The TDA9901 is
optimized for fast switching between different gain
settings, preserving small phase and amplitude error.
The TDA9901 presents an excellent combination of low
noise and good linearity for a wide input frequency range.
The TDA9901 is optimized for processing IF signals in
GSM base stations. It is also suited for many other
applications as a general purpose digitally controlled
variable gain amplifier.
The TDA9901 is able to operate from 4.75 to 5.25 V
supply for the analog part and from 3.0 to 5.25 V for the
digital part.
APPLICATIONS
• Linear AGC systems
• IF amplifier in IF conversion systems (e.g. base stations
or satellite receivers)
• Instrumentation
• Multi-purpose amplifier
• Driver for differential ADCs (e.g. TDA8768).
