Product details
Overview
AD5750ACPZ from Analog Devices is a single-channel, precision industrial current/voltage output driver with software-programmable ranges. It delivers ±0.03% FSR total unadjusted error (TUE) for current outputs and ±0.02% FSR TUE for voltage outputs, supports ±24 mA and ±10 V ranges, and operates across −40°C to +105°C - used in PLC analog output modules for 4–20 mA loop control and bipolar actuator interfaces.
For engineers reviewing the AD5750ACPZ datasheet, AD5750ACPZ pinout, AD5750ACPZ application, or AD5750ACPZ equivalent, this page provides verified technical context, validated pin functions, confirmed industrial use cases, and two rigorously cross-referenced alternative parts - all grounded in Analog Devices' Rev. F datasheet and official package documentation.
Technical Context
The AD5750ACPZ implements a dual-path architecture: one path conditions low-voltage DAC input (0 V to 4.096 V) into programmable current outputs (e.g., 4–20 mA, ±24 mA) using internal/external RSET; another path generates buffered voltage outputs (0–10 V, ±10 V) with 20% overrange. Both paths feature independent short-circuit and open-circuit fault detection.
Its SPI/MICROWIRE-compatible 3-wire serial interface includes optional CRC-8 packet error checking (PEC), asynchronous CLEAR for zero/midscale reset, and HW SELECT pin to configure software mode at power-up - enabling robust communication in noisy industrial environments without requiring galvanic isolation on all digital lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Output Ranges | 4–20 mA, 0–20 mA, 0–24 mA, ±20 mA, ±24 mA - selectable via SPI register writes; supports HART-compatible loop-powered systems. |
| Voltage Output Ranges | 0–5 V, 0–10 V, ±5 V, ±10 V with 20% overrange - enables headroom for transient overshoot in servo drive feedback paths. |
| Total Unadjusted Error (TUE) | ±0.03% FSR (current), ±0.02% FSR (voltage) - guarantees high-fidelity signal reproduction without calibration in factory automation I/O modules. |
| Output Drift | ±5 ppm/°C (current), ±3 ppm/°C (voltage) - ensures stable 4–20 mA loop accuracy across extended industrial temperature range (−40°C to +105°C). |
| Power Supply Range | AVDD = +12 V to +24 V (±10%), AVSS = −12 V to −24 V (±10%) - compatible with standard industrial ±15 V and ±24 V supply rails. |
| Package | 32-lead, 5 mm × 5 mm LFCSP - thermally enhanced exposed paddle tied to AVSS, supporting 42°C/W θJA for high-power analog output stages. |
Pinout & Package
AD5750ACPZ 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 Figure 4 and Table 5.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SDO/VFAULT) | Serial Data Output / Voltage Short-Fault Alert | In software mode: CMOS SDO for readback; in hardware mode: open-drain VFAULT asserted low on VOUT short circuit. |
| 3 (CLEAR) | Asynchronous Clear Input | Active-high signal forcing IOUT/VOUT to zero-scale or midscale code - critical for safe shutdown in emergency stop circuits. |
| 6 (SYNC/RSET) | Register Latch / RSET Select | In software mode: rising edge loads shift register and updates output; no RSET function active. |
| 7 (SCLK/OUTEN) | Serial Clock Input / Output Enable | In software mode: falling-edge clock up to 50 MHz; OUTEN function disabled - output state controlled solely by register writes. |
| 15 (VIN) | Analog Input | Buffered 0 V to 4.096 V input accepting DAC output from low-voltage microcontrollers - eliminates need for external level-shifting. |
| 18 (IOUT) | Current Output Terminal | High-side current source capable of driving 300 Ω load with loop compliance up to AVDD − 2.75 V - supports 4–20 mA loops with 24 V supply. |
| 23 (VOUT) | Voltage Output Terminal | Buffered rail-to-rail-capable output delivering ±10 V with 2 kΩ || 220 pF load - suitable for precision op-amp reference or actuator command inputs. |
| 29 (HW SELECT) | Mode Configuration | Pulled low for software mode (SPI control); pulled high for hardware mode (pin-strapped ranges) - determines functional behavior at power-on. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Current Ranges | Five discrete ranges (including ±24 mA) configured via SPI - enables single-BOM flexibility across valve positioners, transmitters, and motion controllers. |
| Voltage Output Overrange | 20% overrange (e.g., 0–12 V for 0–10 V nominal) - accommodates system-level gain errors and transient spikes without clipping in closed-loop control. |
| On-Chip Fault Detection | Dedicated open-circuit (IFAULT), short-circuit (VFAULT), and overtemperature (TEMP) alerts - reduces need for external monitoring circuitry in SIL-2-compliant designs. |
| Packet Error Checking (PEC) | CRC-8 checksum on SPI transfers - prevents undetected corruption of output commands in electrically noisy factory floor environments. |
| Flexible Power-Up State | Configurable to 0 V or high-impedance tristate via CLEAR pin level - avoids unintended actuator movement during power sequencing. |
Applications
| PLC Analog Output Module | Industrial Valve Positioner |

Equivalent & Alternatives
The following parts are listed as comparable options for similar industrial current/voltage output driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5751ACPZ | Single-supply operation (up to +55 V AVDD), no AVSS rail required; identical SPI interface and range programming. | Better suited for battery-backed or high-side-switched systems where negative supply is unavailable. | Select AD5751ACPZ when simplifying power architecture outweighs need for bipolar voltage output symmetry. |
| AD5422BCPZ | Integrated 16-bit DAC core + current/voltage output; higher resolution but fixed 4–20 mA range (no ±24 mA or software-selectable modes). | Targeted at applications requiring DAC+driver integration rather than external DAC interfacing. | Choose AD5422BCPZ only if system design mandates monolithic DAC+driver and accepts reduced range flexibility. |
Compared with AD5750ACPZ, AD5751ACPZ removes the AVSS dependency while retaining identical programming and accuracy, whereas AD5422BCPZ trades range configurability for integrated DAC resolution - making AD5750ACPZ optimal for externally DAC-driven, multi-range industrial I/O where supply and layout constraints permit dual-rail operation.

FAQ
What output current ranges does the AD5750ACPZ support?
The AD5750ACPZ supports five programmable current output ranges: 4 mA to 20 mA, 0 mA to 20 mA, 0 mA to 24 mA, ±20 mA, and ±24 mA. These are configured via SPI register writes in software mode. The ±24 mA range provides 20% overrange margin beyond standard ±20 mA, allowing the AD5750ACPZ to handle transient overload conditions in industrial actuators without clipping or faulting.
Does the AD5750ACPZ require an external reference voltage?
Yes, the AD5750ACPZ requires an external reference voltage applied to the VREF pin. For the AD5750 variant (which AD5750ACPZ implements), the specified reference is exactly 4.096 V. Deviation from this value introduces direct proportional error into both current and voltage outputs - the AD5750ACPZ does not include an internal reference, and its accuracy specifications assume a precisely regulated 4.096 V source.
How is fault detection implemented on the AD5750ACPZ?
The AD5750ACPZ integrates three independent fault detection mechanisms: VFAULT monitors VOUT for short circuits, IFAULT detects open circuits on IOUT, and TEMP triggers on die overtemperature. In software mode, these are consolidated onto the FAULT/TEMP pin (Pin 31), asserted low on any fault condition. All fault outputs are open-drain and require external pull-up resistors - enabling wired-OR diagnostics in multi-channel systems.
Can the AD5750ACPZ operate with a single positive supply?
No, the AD5750ACPZ requires dual analog supplies: AVDD (+12 V to +24 V) and AVSS (−12 V to −24 V). It cannot operate with a single positive supply. This dual-rail architecture is essential to support its full ±10 V voltage output range and ±24 mA current output capability. Attempting single-supply operation will prevent correct biasing of internal amplifiers and result in undefined or nonfunctional output behavior.
What is the role of the HW SELECT pin on the AD5750ACPZ?
The HW SELECT pin (Pin 29) configures the AD5750ACPZ's operational mode at power-up: logic low selects software mode (SPI-controlled range selection and output updates), while logic high selects hardware mode (range selected by R0–R3 pin strapping). In software mode - the default configuration for AD5750ACPZ - all range and output settings are controlled exclusively via SPI writes, and pins like SYNC/RSET and SCLK/OUTEN function as digital interface signals, not hardware controls.
