Product details
Overview
AD5751ACPZ-REEL7 from Analog Devices is a single-channel, precision industrial voltage/current output driver with software- or hardware-programmable ranges. It delivers ±0.03% FSR typical total unadjusted error (TUE) for current outputs and ±0.02% FSR for voltage outputs, operates from 10.8 V to 55 V AVDD, and supports −40°C to +105°C ambient temperature-enabling use in PLC analog output modules driving 4–20 mA loops and 0–10 V actuators.
For engineers reviewing the AD5751ACPZ-REEL7 datasheet, AD5751ACPZ-REEL7 pinout, AD5751ACPZ-REEL7 application, or AD5751ACPZ-REEL7 equivalent, key selection criteria include programmable I/V range flexibility, on-chip fault detection (open-circuit, short-circuit, overtemperature), SPI/MICROWIRE interface with optional CRC-8 PEC, and 32-lead 5 mm × 5 mm LFCSP package with AVDD loop compliance to AVDD − 2.75 V.
Technical Context
The AD5751ACPZ-REEL7 integrates dual-output architecture: a current output stage (0 mA to 20 mA, 0 mA to 24 mA, or 4 mA to 20 mA) and a separate buffered voltage output (0 V to 5 V, 0 V to 10 V, or 0 V to 40 V), each with independent overrange capability. Its internal RSET option or external 15 kΩ resistor configuration enables optimized temperature drift performance (±5 ppm/°C typical current drift, ±3 ppm/°C voltage drift).
Control is implemented via SPI-compatible 3-wire serial interface (SCLK/OUTEN, SDIN/R0, SYNC/RSET) supporting both software mode (register-based configuration) and hardware mode (pin-strapped range selection). Fault monitoring includes dedicated open-drain outputs for VFAULT, FAULT/TEMP, and NC/IFAULT, with asynchronous CLEAR and power-on reset ensuring deterministic startup behavior.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SDO/VFAULT) | Serial Data Output / Voltage Short-Circuit Alert | In software mode: reads back register data; in hardware mode: asserts low on VOUT short - enables diagnostics without MCU intervention |
| 3 (CLEAR) | Asynchronous Clear Input | Active-high signal forcing zero-scale/midscale output - critical for safe shutdown in emergency stop circuits |
| 6 (SYNC/RSET) | Register Latch / External RSET Select | Rising edge loads input shift register; logic level selects internal/external current sense resistor - determines drift performance path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar industrial I/V output driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5422ACPZ-REEL7 | Integrated 16-bit DAC + current/voltage output; higher resolution but no VSENSE+; larger 40-lead LFCSP | Best for new designs requiring DAC integration and higher resolution; less suitable for retrofit where AD5751 footprint is fixed | Select AD5422 when system-level DAC integration reduces board area and cost outweighs need for remote sense |
| XTR300PWR | 4–20 mA only (no voltage output); integrated HART modem; 24-pin TSSOP; lower TUE (±0.015% FSR) | Targeted at HART-enabled field instruments; lacks dual-output flexibility and voltage capability of AD5751 | Choose XTR300 for HART-compliant 4–20 mA transmitters where voltage output is unnecessary |
Compared with AD5751ACPZ-REEL7, AD5422 offers higher integration (on-chip DAC) but sacrifices remote sensing and increases package size, while XTR300 provides superior current accuracy and HART support but eliminates voltage output entirely-making AD5751 the optimal choice for dual-mode, remotely sensed, non-HART industrial I/O.

FAQ
What output ranges does the AD5751ACPZ-REEL7 support?
The AD5751ACPZ-REEL7 supports three current output ranges: 0 mA to 20 mA, 0 mA to 24 mA, and 4 mA to 20 mA; and three voltage output ranges: 0 V to 5 V, 0 V to 10 V, and 0 V to 40 V. Each range includes programmable overrange capability (e.g., 0–12 V on 0–10 V range). The AD5751ACPZ-REEL7 implements these via internal register settings in software mode or hardware pin strapping in hardware mode.
How does the AD5751ACPZ-REEL7 handle fault conditions?
The AD5751ACPZ-REEL7 provides comprehensive on-chip fault detection: open-circuit (IOUT), short-circuit (VOUT), overtemperature, and PEC interface errors. These trigger dedicated open-drain outputs - FAULT/TEMP and SDO/VFAULT - which assert low and can be monitored by an external microcontroller or PLC input. The AD5751ACPZ-REEL7 also features automatic output disable during fault events to protect downstream circuitry.
Can the AD5751ACPZ-REEL7 drive inductive or capacitive loads directly?
Yes, the AD5751ACPZ-REEL7 is designed to drive real-world industrial loads: it remains stable with inductive loads up to 0.1 H and capacitive loads up to 1 μF without external compensation. For larger capacitive loads, optional compensation capacitors can be connected between COMP1 and COMP2 pins. This capability allows direct connection to solenoids, valves, and analog displays without additional buffer stages.
What is the role of the VSENSE+ pin on the AD5751ACPZ-REEL7?
The VSENSE+ pin on the AD5751ACPZ-REEL7 enables remote voltage sensing at the load to compensate for voltage drop across long wiring runs. When enabled, the AD5751ACPZ-REEL7 adjusts its VOUT drive to maintain the commanded voltage precisely at the remote terminal - critical for maintaining accuracy in distributed control systems with 100+ meter cable runs. It is not used in current-output mode.
Does the AD5751ACPZ-REEL7 require external components for basic operation?
The AD5751ACPZ-REEL7 operates with minimal external components: only decoupling capacitors on AVDD and DVCC, and optionally a 15 kΩ external RSET resistor between REXT1 and REXT2 to improve current-output temperature drift. No external op-amps, transistors, or precision resistors are needed for standard 4–20 mA or 0–10 V operation - simplifying BOM and layout for AD5751ACPZ-REEL7-based designs.
