Product details
Overview
AD5750-1ACPZ from Analog Devices is a single-channel, precision industrial current/voltage output driver with software-programmable ranges. It supports five current ranges (including 4 mA to 20 mA and ±20 mA) and four voltage ranges (including 0 V to 10 V and ±10 V), delivers ±0.03% FSR total unadjusted error, ±5 ppm/°C current drift, and operates from −40°C to +105°C in process control loop interfaces.
For engineers reviewing the AD5750-1ACPZ datasheet, AD5750-1ACPZ pinout, AD5750-1ACPZ application, or AD5750-1ACPZ equivalent, this page provides verified functional identity, confirmed SPI/MICROWIRE interface behavior, validated 32-lead LFCSP package mapping, real-world fault detection implementation details, and precise range-programming constraints for PLC analog output module design.
Technical Context
The AD5750-1ACPZ implements dual-path analog output architecture: a current output stage with internal/external RSET selection and a separate buffered voltage output stage with programmable overrange up to 20%. Its input accepts 0 V to 2.5 V analog signals (confirmed for AD5750-1 variant), conditioned internally to drive compliant loads up to AVDD − 2.75 V.
It features hardware/software mode selection via HW SELECT pin, SPI-compatible 3-wire serial interface with optional CRC-8 packet error checking (PEC), asynchronous CLEAR for zero/midscale reset, and integrated open-circuit, short-circuit, and overtemperature fault detection routed to dedicated open-drain alert pins (VFAULT, FAULT/TEMP, NC/IFAULT).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Output Ranges | 4 mA to 20 mA, 0 mA to 20 mA, 0 mA to 24 mA, ±20 mA, ±24 mA - enables universal 4–20 mA loop, zero-based actuator control, and bipolar sensor simulation |

Pinout & Package
AD5750-1ACPZ uses a 32-lead, 5 mm × 5 mm LFCSP package with exposed thermal paddle connected to AVSS. Pin functions are validated per Analog Devices Rev. F datasheet (Page 11–12), distinguishing software-mode (default) operation where pins like SDO/VFAULT, FAULT/TEMP, and NC/IFAULT serve digital interface and fault reporting roles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SDO/VFAULT (Pin 1) | Serial Data Output / Voltage Short-Circuit Alert | In software mode: CMOS SDO for readback; asserted low on VOUT short-circuit - enables real-time loop integrity monitoring without additional comparators |
| CLEAR (Pin 3) | Asynchronous Reset Input | Active-high signal forcing zero-scale (unipolar) or midscale (bipolar) output - critical for safe startup and emergency shutdown in safety-critical actuators |
| VIN (Pin 15) | Analog Input | 0 V to 2.5 V buffered input (AD5750-1 specific) - interfaces directly with low-voltage DACs or microcontroller DAC outputs without level-shifting |
| IOUT (Pin 18) | Current Output Driver | High-side current source/sink capable of driving 300 Ω load at full scale - delivers industry-standard 4–20 mA into field transmitters or valve positioners |
| VOUT (Pin 23) | Voltage Output Buffer | Low-impedance buffered output supporting 2 kΩ || 220 pF load - drives PLC analog inputs, data acquisition front-ends, or calibration references |
| HW SELECT (Pin 29) | Mode Configuration Input | Pull-to-GND selects software mode (SPI control); pull-to-DVCC selects hardware mode (pin-strapped ranges) - defines system-level configuration strategy |
| FAULT/TEMP (Pin 31) | General Fault Alert / Overtemperature Indicator | In software mode: open-drain active-low alert for open-circuit, short-circuit, overtemp, or PEC errors - consolidates multiple failure modes into one interrupt line |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Current Ranges | Five discrete ranges including 4–20 mA and ±24 mA - eliminates need for external range-switching relays or op-amp reconfiguration in multi-sensor systems |
| Voltage Output Overrange | 20% programmable overrange (e.g., 0–12 V on 0–10 V setting) - accommodates sensor headroom, amplifier offsets, and margin requirements in closed-loop control |
| Integrated Fault Detection | Dedicated open-drain alerts for VOUT short, IOUT open, overtemperature, and PEC errors - reduces BOM count by replacing discrete fault-monitoring ICs |
| Flexible Power-Up State | Configurable to 0 V or tristate via CLEAR pin level at power-on - prevents spurious actuator movement during controller boot-up sequences |
| External RSET Support | REXT1/REXT2 pins accept 15 kΩ resistor to improve IOUT temperature drift - enables <±2 ppm/°C current stability when paired with precision metal-film resistors |
Applications

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 |
|---|---|---|---|
| AD5751 | Single-supply operation (up to +55 V AVDD), no AVSS rail required; identical software-programmable ranges and fault detection | Better suited for battery-powered or single-rail industrial gateways; lacks bipolar current capability (±20/±24 mA) | Select AD5751 when board space or supply complexity limits dual-rail implementation, but verify bipolar range requirements are not needed. |
| AD5420 | 16-bit DAC + current source in one chip; fixed 4–20 mA output only; no voltage output or programmable ranges | Targeted at cost-sensitive, fixed-range applications; requires external op-amp for voltage output | Choose AD5420 only if 4–20 mA-only functionality suffices and integrated DAC resolution is prioritized over flexibility. |
Compared with AD5750-1ACPZ, AD5751 simplifies power design but sacrifices bipolar current output, while AD5420 reduces component count for fixed-range use but eliminates voltage output and range configurability - making AD5750-1ACPZ the optimal choice for flexible, dual-output, dual-rail industrial modules.

FAQ
What is the analog input voltage range supported by the AD5750-1ACPZ?
The AD5750-1ACPZ accepts a 0 V to 2.5 V buffered analog input on the VIN pin (Pin 15), as explicitly specified for the AD5750-1 variant in the Rev. F datasheet Table 2. This differs from the AD5750 (0–4.096 V) and AD5750-2 (0–2.5 V with different reference). Using a 2.5 V full-scale input ensures optimal accuracy alignment with its internal scaling architecture.
Does the AD5750-1ACPZ support both current and voltage outputs simultaneously?
No, the AD5750-1ACPZ does not support simultaneous current and voltage output. It provides independent IOUT (Pin 18) and VOUT (Pin 23) terminals, but the device is configured to drive one output type at a time per channel. The internal architecture routes the same VIN signal through separate conditioning paths - users must select either current or voltage mode in system firmware.
How is output fault detection implemented on the AD5750-1ACPZ?
The AD5750-1ACPZ implements three dedicated fault detection channels: VOUT short-circuit (reported on SDO/VFAULT), IOUT open-circuit (reported on NC/IFAULT in hardware mode or FAULT/TEMP in software mode), and overtemperature (reported on FAULT/TEMP). All alerts are open-drain and require external pull-up resistors, enabling direct connection to MCU GPIO interrupt pins for real-time diagnostics.
What is the purpose of the REXT1 and REXT2 pins on the AD5750-1ACPZ?
The REXT1 (Pin 12) and REXT2 (Pin 13) pins accept an external 15 kΩ precision resistor to replace the internal current sense resistor. Per the Rev. F datasheet (Page 12), this improves IOUT temperature drift performance - achieving <±2 ppm/°C versus ±5 ppm/°C with internal RSET - critical for high-stability applications like calibration equipment or metrology-grade controllers.
Can the AD5750-1ACPZ operate with a single positive supply?
No, the AD5750-1ACPZ requires dual analog supplies: AVDD (+12 V to +24 V) and AVSS (−12 V to −24 V), as stated in the Absolute Maximum Ratings (Table 4) and Power Requirements (Page 7). It cannot operate with a single positive supply; attempting to do so violates absolute maximum ratings and will result in nonfunctional or damaged output stages.
