Evaluating the ADA4350, a FET Input Analog Front End With ADC Driver

FEATURES

Enables quick breadboarding/prototyping
User defined circuit configuration
Edge mounted SMA connector provisions
Easy connection to test equipment and other circuits
Guard ring to minimize leakage currents

GENERAL DESCRIPTION

The
EVAL-ADA4350RUZ-P
help users evaluate the
ADA4350
6.4 mm thin shrink small outline package (TSSOP). The eval-
uation board is a populated board that enables users to quickly
prototype the best configuration of the analog front end for
their systems. Figure 1 shows the component side of the bare
evaluation board, and Figure 2 shows the solder side of the bare
evaluation board.

EVAL-ADA4350RUZ-P User Guide
The evaluation board is a 6-layer printed circuit board (PCB)
designed to minimize leakage currents with its guard ring
features. It accepts SMA edge mounted connectors on the
inputs and outputs for efficient connection to test equipment or
other circuitry.
The evaluation board components are primarily SMT 0603 case
size, with the exception of the electrolytic bypass capacitors (C9,
C10, and C13), which are 1206 case size.
Figure 10 shows the
amplifier with multiple gains when a dual supply is used.
Figure 3 and Figure 4 show the signal gain/noise gain of the
board when configured as Figure 10. Figure 7 to Figure 9 show
the guard ring details. Figure 11 shows the assembly drawing
and Figure 12 shows the 6-layer stackup along with the
dimensions for each layer. The bill of materials is listed in
Table 2.
