EVALUATION BOARD HARDWARE
The ADA4870ARR-EBZ evaluation board is a 6-layer board. All
signal routing is on the top layer; the bottom layer is an exposed
copper ground plane to facilitate the use of a heat sink. The heat
sink is needed for high power dissipation projects, such as driving
a 20 Ω load with the maximum output swing. The internal layers
(Layer 2 through Layer 5) consist of the GND, VCC, VMID, and
VEE planes.
POWER SUPPLIES AND DECOUPLING
The evaluation board can be powered using a single supply or
dual supplies. The total supply voltage (VCC − VEE) must be
between 10 V and 40 V. The board provides sufficient power
supply decoupling for high current, fast slewing signals with
22 μF and 10 μF tantalum capacitors installed at C1 and C2 where
the VCC supply voltage is applied to the board; 22 μF and 10 μF
tantalum capacitors are installed at C22 and C23 where the VEE
supply voltage is applied to the board. In addition, 0.1 μF ceramic
chip capacitors (C4 and C5) are placed in close proximity to the
VCC pins (Pin 1, Pin 18, Pin 19, and Pin 20). And 0.1 μF ceramic
chip capacitors (C25 and C26) are placed in close proximity to
the VEE pins (Pin 10, Pin 11, Pin 12, and Pin 13).
SYMMETRICAL SUPPLIES AND DC-COUPLED
INPUTS
Figure 3 shows the noninverting or inverting configuration
schematic when using dual, symmetrical supplies. When using
the factory default settings with noninverting input, the ground
reference is established through the 49.9 Ω termination resistors
(R17 and R18), and the gain can be calculated using R20/(R19 +
R18). The gain is +4.5 V/V for the factory default settings.
When using the factory default settings with inverting input,
the gain can be calculated using R20/R19. The gain is −4.0 V/V
for the factory default settings. In dual-supply operation when
installing R30 in either inverting or noninverting applications,
position the jumper at P4 to short VMID to GND.
INPUT AND OUTPUT
Figure 10 shows the evaluation board schematic for the factory
default settings when the board is shipped.
The evaluation board uses edge-mount SMA connectors on the
inputs and outputs for easy interfacing to signal sources and test
equipment. When evaluating high voltage output signals using
standard 50 Ω test equipment, R29 can be replaced with a
2.45 kΩ resistor that provides a signal division of 49.6 at the
DIV_OUT SMA connector. The board can accommodate a
capacitor load (C71) referenced to GND, and/or a power
resistor in the TO-220 package (R30) referenced to VMID.
When using input signals of 5 V and lower, the board is
equipped with 49.9 Ω, 0.25 W resistors at R17 and R18 that are
capable of handling the power when using the factory default
settings. The factory default configuration provides for
operation on dual symmetrical supplies in noninverting and
inverting gains of +4.5 V/V, and −4.0 V/V respectively. For
single-supply and asymmetrical supply operation, see the
Asymmetrical Supplies and Mid Supply Bias (VMID) section
and Table 1 for guidance on configuring the input terminations
and supply settings.

Figure 4 and Figure 5 show schematics when using a single
supply with ac-coupled input.
When ac coupling into the noninverting input (INP), the dc
operating point of the amplifier can be established by installing
a resistor at R9 connected to VMID and replacing R1 with an ac
coupling capacitor (C1), as shown in Figure 4. The ac coupling
capacitor (C1) combined with the VMID bias resistor (R9) form
a high-pass filter with the cutoff frequency at 1/(2 × π × R9 × C1).
The value of the ac coupling capacitor (C1) can be calculated
based on the desired cutoff frequency.
When ac coupling into the inverting input (INN), the dc
operating point of the amplifier can be established by shorting
R9 to VMID. Do not install R1.

The ADA4870 must be referenced to a dc operating point. When
using a single supply or asymmetrical dual supplies, apply the
appropriate reference voltage to the VMID pin of P4 using a low
impedance source, such as a dc supply. The recommended VMID
reference voltage is VEE + (VCC – VEE)/2.

the amplifier. Do not float the pin. When turning the amplifier
back on from the shutdown state, pull the SD pin high and then
pull the ON pin low. Following this sequence is required to turn
on the ADA4870. To enable the short-circuit protection, the
ON pin must float following the turn on sequence.
ON, INITIAL POWER-UP, AND SHORT CIRCUIT
The board is shipped with the ON pin pulled low to VEE at P1 to
ensure that the amplifier is enabled. Subsequently, floating the
ON pin enables the short-circuit protection feature while the
amplifier remains on. While ON is held low, the short-circuit
protection feature is disabled.
THERMAL MONITOR/SHORT-CIRCUIT FLAG (TFL)
The TFL pin can be used to monitor relative changes in die
temperature and to detect a short-circuit condition. During
normal operation, the TFL pin outputs a dc voltage that is
approximately 1.7 V (typical) above VEE and is related to the
die temperature. The TFL voltage changes at approximately
−3 mV/°C. When the die temperature exceeds approximately
140°C, the amplifier switches to an off state, dropping the
supply current to approximately 5 mA while TFL continues to
report a voltage indicative of the die temperature. When the
die temperature returns to an acceptable level, the amplifier
automatically resumes normal operation.
The ON pin turns on the amplifier after initial power-up and
after a short-circuit event. The pin is referenced to the negative
supply (VEE).
When a short-circuit condition is detected, the amplifier is
disabled, the supply current drops to approximately 5 mA, and
the TFL pin outputs a dc voltage of approximately 300 mV above
VEE. To turn the amplifier back on after a short-circuit event,
follow the previously described sequence for initial power-up.
Pulling the ON pin high disables the amplifier and causes the
supply current to drop to approximately 5 mA, as if a shortcircuit condition had been detected. Pin 3 of P2 uses a 5 V
Zener diode (CR1) to set the high level at 5 V above VEE.
THERMAL DESIGN AND HEAT SINK SELECTION
In some applications, the ADA4870 may be required to dissipate
as much as 10 W at elevated ambient temperatures of up to +85°C.
The evaluation board provides robust thermal management
under these conditions.
The impedance at ON is approximately 20 kΩ. The ON pin is
decoupled to VEE via C8 to shunt noise away from ON and to help
avoid false triggers.
SHUTDOWN (SD)
The top of the board has an exposed copper area to which the
ADA4870 PSOP package must be soldered. The exposed copper
area allocated to the attachment of the PSOP slug is connected
to the exposed copper ground plane on the bottom by an array
of 136 thermal vias. A single internal ground layer (Layer 2) is
also attached. Figure 6 shows a model of the ADA4870 package
mounted to the evaluation board with an applied heat sink.
The board factory default setting for the (P3) jumper pulls the
SD pin to the HI position, VEE + 5.2 V. Pulling the SD pin low
to VEE places the amplifier in a low power shutdown state,
reducing the quiescent current to approximately 750 μA. The
SD pin must be pulled low to a maximum of VEE + 0.9 V for
shutdown, or pulled high to a minimum of VEE + 1.1 V to enable

When necessary, a heat sink can be mounted to the bottom
exposed copper using the mounting holes and an applied
thermal interface material (TIM), such as the GC Electronics
10-8109. Refer to the manufacturer guidelines when applying
the TIM; the TIM thermal resistance (θTIM) must be no more
than 0.3°C/W. See Figure 7 for the dimensions of the heat sink
and mounting hole locations. The approximate thermal
resistance of the heat sink can be calculated from Equation 1,
where θJC equals 1.1°C/W and θCBOT is approximately equal to
1.0°C/W. A heat sink having a thermal resistance of 4.2°C/W
allows 10 W of power dissipation at an ambient temperature
of 85°C.

Figure 8 and Figure 9 show the die temperature vs. time while
the internal power dissipation is increased over several hours.
The ambient environment for Figure 8 is 25°C in still air; for
Figure 9, the ambient environment is 85°C in still air. Figure 8
shows the die temperature in two conditions: one without a heat
sink and the other with a heat sink rated at 5.4°C/W. Figure 9
shows the die temperature in three conditions: one without a
heat sink, the second with a heat sink rated at 5.4°C/W, and the
third with a heat sink rated at 4.2 °C/W. For both Figure 8 and
Figure 9, the board is positioned with the bottom side or heat
sink facing up to facilitate natural convection. Using ac power
dissipation and/or forced convection result in lower temperature.
