Analog Devices Inc. EVAL-ADFS5758SDZ

Overview

EVAL-ADFS5758SDZ from Analog Devices is a functional safety–certified evaluation board for the ADFS5758 single-channel, 16-bit current/voltage output DAC. It integrates an on-board ADR4525 2.5 V reference, ADP1031-1 isolated power management unit with SPI signal isolation, and supports unipolar current output mode per IEC 61508 SIL 2 requirements.

For engineers reviewing the EVAL-ADFS5758SDZ datasheet, EVAL-ADFS5758SDZ pinout, EVAL-ADFS5758SDZ application, or EVAL-ADFS5758SDZ equivalent, this board enables rapid validation of ADFS5758 performance in industrial process control loops, functional safety–compliant analog output modules, and HART-enabled field instrumentation - with ACE software-based register-level control, diagnostic monitoring, and DC-DC converter configuration.

Technical Context

The EVAL-ADFS5758SDZ interfaces exclusively with the EVAL-SDP-CS1Z system demonstration platform via SPI, using SDP-S to drive RESET, LDAC, and monitor FAULT. It relies on the ADP1031-1 PMU to generate AVDD1 (+26.7 V), AVDD2 (+5.15 V), and AVSS (−15.4 V), while VLOGIC is supplied either from SDP-S (3.3 V) or the ADFS5758's VLDO output.

Reference selection is configurable between the internal ADFS5758 reference and the external ADR4525 via JP5; address pins AD0/AD1 are set via JP7/J8; and dynamic power control (DPC) operation is enabled or bypassed using JP6. All link options-including JP1–JP13 and P10-are documented in UG-1688 with default positions and functional impact.

FAQ

What equipment is required to operate the EVAL-ADFS5758SDZ?

The EVAL-ADFS5758SDZ requires the EVAL-SDP-CS1Z system demonstration platform for USB-to-SPI communication, a benchtop power supply capable of delivering −33 V to +33 V across AVSS and AVDD1 rails (max 60 V differential), and connector cables. The ACE software must be installed separately, and the ADFS5758 plugin loaded to enable full register control and diagnostics on the EVAL-ADFS5758SDZ.

Does the EVAL-ADFS5758SDZ support both voltage and current output modes of the ADFS5758?

Yes, the EVAL-ADFS5758SDZ fully supports both voltage and current output configurations of the ADFS5758. Its hardware includes jumper-selectable reference paths (JP5), configurable address pins (JP7/J8), and link options (JP1, JP6, JP12) that enable evaluation of unipolar current output (4–20 mA), bipolar voltage output (±10 V), and HART-enabled operation - all verified in UG-1688 Rev. 0.

How is functional safety validation performed using the EVAL-ADFS5758SDZ?

The EVAL-ADFS5758SDZ enables functional safety validation by exposing the ADFS5758's built-in diagnostics - including digital diagnostic results (via R/W to DIG_DIAG_STATUS), analog diagnostic results (ANALOG_DIAG_STATUS), watchdog timer configuration, and fault pin monitoring - through the ACE software interface. Diagnostic flags are cleared and updated via dedicated buttons in the GUI, and all safety-related register behavior aligns with IEC 61508 SIL 2 requirements as stated in the ADFS5758 data sheet.

Can the EVAL-ADFS5758SDZ operate without the EVAL-SDP-CS1Z board?

No - the EVAL-ADFS5758SDZ is not standalone. It requires the EVAL-SDP-CS1Z for SPI communication, RESET/LDAC control, and FAULT monitoring. However, P10 jumpers allow disconnection from the SDP-S board to drive digital signals externally; doing so requires replicating SDP-S timing, voltage levels, and sequencing - which is unsupported in standard operation and not validated in UG-1688.

What is the role of the ADP1031-1 on the EVAL-ADFS5758SDZ?

The ADP1031-1 serves as an isolated power management unit on the EVAL-ADFS5758SDZ, generating three critical supplies for the ADFS5758: AVDD1 (+26.7 V), AVDD2 (+5.15 V), and AVSS (−15.4 V). It also provides SPI signal isolation, power-good indication (PWRGD), and supports dynamic power control (DPC) circuitry. Its outputs are configurable via JP13 (AVDD1), JP12 (AVDD2), and JP1 (AVSS), per Table 1 in UG-1688.
