The signal routings are on Layer 1 (top) and Layer 4. The bottom layer is an exposed copper ground plane used for heat dissipation and heat sink attachment. Internal Layer 2 through Layer 5 are the VCC, VMID, signal, and VEE planes, respectively. The EVAL-ADHV4702-1CPZ evaluation board is divided into two sections as shown in Figure 3. The upper section is the test circuit for the ADHV4702-1, and the lower section is the optional on-board power management circuit comprising an LT8304-1 monolithic micropower isolated flyback converter. The connection of these two sections can be made via the P1, P4, and P5 connectors. Refer to the Initial Power-Up section for more information. test circuit via the P1, P4, and P5 connectors. For ±110 V dual supplies, jump VCC_TRANSFORMER to VCC, VEE_ TRANSFORMER to VEE, and GND_TRANSFORMER to AGND. The LT8304-1 on-board power management circuit can also provide a single supply of 220 V. The schematic for the on-board power management circuit is shown in Figure 5. For more information, refer to the LT8304-1 data sheet for different voltage output options. POWER SUPPLIES AND DECOUPLING The EVAL-ADHV4702-1CPZ evaluation board can be powered using a single supply or dual supplies. The total supply voltage (VCC − VEE) must be between 24 V and 220 V. When using a single supply or asymmetrical dual supplies, apply the appropriate reference voltage to the VMID pin of P2 using a low impedance source, such as a dc power supply. The recommended VMID reference voltage is (VCC + VEE)/2. ADHV4702-1 TEST CIRCUIT The EVAL-ADHV4702-1CPZ board provides sufficient power supply decoupling for fast slewing signals with 1.2 µF (C1, C2), 250 V ceramic chip capacitors where the supply voltage enters the board. Two 0.1 µF, 250 V ceramic chip capacitors (C3, C5) are placed in close proximity to VCC at Pin 7. Two capacitors (C4, C6) are placed in close proximity to VEE at Pin 4. LT8304-1 POWER MANAGEMENT CIRCUIT 17224-003 INPUT AND OUTPUT Figure 3. Evaluation Board Test and Power Management Circuits INITIAL POWER-UP The EVAL-ADHV4702-1CPZ evaluation board is shipped for use with dual symmetrical power supplies. Before applying power to the board, apply the jumper from the VMID node to the AGND node (see Figure 4) via P2, using the 2-pin header, to provide a dc operating point for the amplifier. The EVAL-ADHV4702-1CPZ evaluation board can be powered up using the external power supply or the on-board LT8304-1 power management circuit. To power up the board using an external power supply, apply the power at the PWR header or via the GND, VCC, and VEE test points. The quiescent supply current is approximately 3 mA. In addition to the quiescent current, there is an additional ~2.2 mA from the VCC supply to bias the D1 Zener diode clamp at the SDN connector. The LT8304-1 on-board power management circuit can be used to provide dual supplies of approximately ±110 V from a convenient 15 V dc input. Apply 15 V dc from an external power supply at the VIN_15V test point or by using a 15 V dc wall transformer type plugin at P6. Connect the outputs from the on-board power management circuit to the ADHV4702-1 Figure 4 and Figure 5 show the evaluation board schematics for the factory default settings. The evaluation board uses edge mount SMA connectors on the inputs and outputs for easy interfacing to signal sources and test equipment. In addition, the board accepts SMB connectors on the inputs for efficient connection to other circuitry such as the EVAL-AD5754REBZ DAC evaluation board. The EVAL-ADHV4702-1CPZ evaluation board is equipped with 49.9 Ω termination resistors at R1 and R2. The power rating of the termination resistors is 1 W, which are capable of handling the power when using the factory default settings. The termination resistance can be removed or replaced with a different value based on the output impedance of the selected input signal source. The EVAL-ADHV4702-1CPZ evaluation board accommodates a default 10 kΩ, 1210 resistor load (R25) to VMID, or a 1210 capacitor load referenced to AGND. The EVAL-ADHV4702-1CPZ evaluation board is in a default noninverting configuration with a gain of ~21 V/V and a feedback resistance of 39.2 kΩ. In this configuration, the amplifier delivers about 10 mA peak to the load at the maximum output swing. DIGITAL GROUND (DGND) The DGND pin sets a common signal ground for communication to a microprocessor or other low voltage logic circuit. The DGND pin voltage is also the reference for all the low voltage pins of the amplifier such as RADJ, TMP, and SD. DGND is connected to the 0 V AGND on the evaluation board. Rev. 0 | Page 3 of 10 UG-1444 EVAL-ADHV4702-1CPZ User Guide SHUTDOWN FEATURE (SDN CONNECTOR) The SD pin of the ADHV4702-1 can be jumped to logic high, logic low, or can be left floating via the SDN connector on the EVAL-ADHV4702-1CPZ evaluation board. The SD pin is left floating at the SDN connector as shipped from the factory, enabling the amplifier. Pulling the SD pin low to DGND places the amplifier in a power saving shutdown mode. When turning the amplifier back on from the shutdown state, float the SD pin or pull it high. INPUT CLAMPING DIODES To protect the amplifier from high dynamic power dissipation, the EVAL-ADHV4702-1CPZ evaluation board is configured by default with input clamping diodes (D6 and D7) that clamp the input differential voltage of the ADHV4702-1 at a two-diode forward bias voltage. This input clamping network limits the drive to the slew boosting circuit, which affects dynamic performance such as bandwidth and slew rate. The recommended part number for the input clamping diodes is SBAV199LT1G. Removing the input clamping diodes allows the slew boosting circuit to be fully biased, which maximizes slew rate and improves settling time significantly. The fully biased slew boosting circuit requires additional supply current and results in higher power dissipation during slewing. For reliable operation, always operate the amplifier within the safe operating area curve and provide additional heat sinking as required for the application. Refer to the ADHV4702-1 data sheet for more information. INPUT GUARD RING The EVAL-ADHV4702-1CPZ evaluation board employs an electrostatic guard ring on the top layer to reduce printed circuit board (PCB) surface leakage currents. The guard ring encircles the noninverting input and must be biased at the same voltage as the input. The guard ring can be biased using a voltage source at P3 or connected to the noninverting input by installing a 0 Ω resistor at R10. Remove the input clamping diodes (D6 and D7) to ensure the complete enclosure of the high impedance input node. THERMAL MONITOR/FLAG (TMP) AND THERMAL MANAGEMENT The TMP pin can be used to monitor relative changes in die temperature. The typical TMP pin voltage at room temperature is approximately 1.9 V and changes at approximately −4.5 mV/°C. More precise temperature readings can be achieved through a single-point (offset) ambient temperature calibration. This calibration can be accomplished by measuring the TMP pin to establish the precise voltage corresponding to ambient temperature. To avoid calibration error due to self heating, power up the device in shutdown mode (hold SD low at supply turn on) and maintain it in shutdown mode until the TMP pin voltage is measured. The TMP pin can be connected to the SD pin by installing a 0 Ω resistor at R8 to enable the overtemperature and short-circuit protection features. Install a resistor at RTEMP to set the thermal shutdown threshold temperature. Refer to the ADHV4702-1 data sheet for more information about the temperature monitor and short-circuit protection. The ADHV4702-1 evaluation board is designed with an exposed copper top layer for robust thermal management. Solder the exposed pad (EPAD) of the package to the copper layer to ensure optimal thermal dissipation. The top exposed copper area is connected to the exposed copper ground plane on the bottom by an array of five thermal vias. In addition, a heat sink can be attached to the bottom exposed ground plane to increase the power dissipation capability of the ADHV4702-1. RESISTOR ADJUSTABLE QUIESCENT CURRENT (RADJ) The EVAL-ADHV4702-1CPZ evaluation board is configured by default with a 0 Ω RADJ resistor that fully biases the amplifier and sets the supply current to 3 mA. Increasing the value of RADJ reduces the quiescent current, lowering the bandwidth and slew rate of the amplifier while also reducing quiescent power dissipation. Refer to the ADHV4702-1 data sheet for more information about RADJ. Rev. 0 | Page 4 of 10 VEE 22-12-2034 AGND Figure 4.
