The S510067 consists of an input Linear AGC amplifier and a
video/AGC amplifier. The amplifiers are designed to interface
directly with saw filters and A/D converters The AGC is delayed
between the two blocks for optimal NF and IM3 performance
across the full AGC range. The final stage is capable of
providing 2 V
PP
into a 500Ω load. The part is offered in the
QFN28 & 20 TSSOP package and is RoHS compliant.

TYPICAL APPLICATION CIRCUIT
Input Amplifier
This amplifier provides a maximum gain of 39 dB. The gain
is controlled by applying a DC voltage (from 0 to 3 V) to the AGC
pin, providing 27 dB of range. The output stage current can
be set between 10 mA (R = 20) and 30 mA (R = 0) by
connecting an external resistor from pin 1 to ground.
Video Amplifier
This amplifier provides a maximum gain of 47 dB. The gain
is controlled by applying a DC voltage (from 0 to 3 V) to the AGC
pin, providing 27 dB of range. The outputs of the video amp
are both open drain and require pull-up inductors to V
DD.
Up
to 2 V
PP
can be delivered into a 500
Ω
load.
The input amplifier and video amplifier are controlled by a
single AGC so the overall dynamic range is the sum of the
input amplifier range and the video amplifier range.
