4 Power-Supply Connections
The power-supply connections for the ALM2403Q1EVM are provided through connector J7 at the top of
the EVM. Table 3 summarizes the pin definition for supply connector J7, and the allowed voltage range for
each supply connection.
Table 3. ALM2403Q1EVM Supply-Range Specifications
Pin Number Supply Connection Voltage Range
J7.1 Input stage supply (VCC) 5 V to 24 V
J7.2 Ground 0 V
The ALM2403Q1 is configured to use a single supply connected through J7.1 (VCC) and J7.2 (GND). By
default, jumper J5 is set to shunt pins 2-3 placing a Schottky diode (D1) in series with the power supply
connection. The Schottky diode blocks any reverse current into the VCC_S supply during a fault condition
when the output of the amplifier is shorted to a higher potential than the VCC_S supply. Place J5 to shunt
pins 1-2 to bypass the optional diode (D1). Figure 3 shows the ALM2403Q1EVM voltage supply
connections.

6 Modifications
By default, the ALM2403Q1EVM is populated with both amplifiers set to the inverting configuration.
However, for flexibility, the PCB layout has additional unpopulated passive component footprints, and
additional input connections. These additional component footprints in the layout allow the user to change
the ALM2403Q1 circuit to other common configurations, such as the buffer and noninverting amplifier
configurations. For a full schematic of the ALM2403Q1EVM, see Figure 5.
7 Schematic, PCB Layout, and Bill of Materials
This section contains the schematic, bill of materials, and references for the ALM2403Q1EVM.
7.1 Schematic
Figure 5 illustrates the EVM schematic.
NOTE: DNP components are not populated.
Figure 5. ALM2403Q1EVM Schematic
7.2 PCB Layout
The ALM2403Q1EVM is a four-layer PCB design. Figure 6 to Figure 10 show the PCB layer illustrations.
The top layer consists of all signal path traces, and is poured with a solid ground plane. A symmetrical
board layout is used on amplifier 1 and amplifier 2 to keep good performance matching. Decoupling
capacitors C4, C5, and C10 are positioned on the top layer as close as possible to the power supply pins
of the device. The second internal layer is a dedicated solid GND plane. Independent vias are placed at
the ground connection of every component to provide a low-impedance path to ground. The third internal
layer and the bottom layer route the power-supply connections.
