Product details
Overview
AD5750-2BCPZ from Analog Devices is a single-channel, precision industrial current/voltage output driver with software-programmable ranges. It supports five current outputs (4–20 mA, 0–20 mA, 0–24 mA, ±20 mA, ±24 mA) and four voltage outputs (0–5 V, 0–10 V, ±5 V, ±10 V with 20% overrange), features ±0.03% FSR TUE for current and ±0.02% FSR TUE for voltage, and operates across −40°C to +105°C in process control loop interfaces.
For engineers reviewing the AD5750-2BCPZ datasheet, AD5750-2BCPZ pinout, AD5750-2BCPZ application, or AD5750-2BCPZ equivalent, key selection considerations include its dual-mode SPI/MICROWIRE interface, on-chip fault detection (open/short-circuit, overtemperature), programmable overrange capability, ±12 V to ±24 V dual analog supply operation, and 32-lead 5 mm × 5 mm LFCSP package compatibility with isolated PLC I/O modules.
Technical Context
The AD5750-2BCPZ implements a digitally controlled, high-accuracy output stage that accepts a buffered 0 V to 2.5 V analog input (VIN) and conditions it via internal scaling and sense circuitry to deliver precise current or voltage outputs. Its architecture integrates separate current-sink/source and voltage-buffer paths, each with independent fault monitoring and compensation networks (COMP1/COMP2).
It operates in software mode by default (HW SELECT = 0), using an SPI-compatible 3-wire serial interface with optional CRC-8 packet error checking (PEC), asynchronous CLEAR, and power-on reset to 0 V or tristate. Output loop compliance reaches AVDD − 2.75 V, supporting capacitive loads up to 1 µF and inductive loads up to 0.1 H with external compensation.

Pinout & Package
AD5750-2BCPZ uses a 32-lead, 5 mm × 5 mm lead-frame chip-scale package (LFCSP) with exposed paddle tied to AVSS. Pin functions are shared between software and hardware modes, requiring correct HW SELECT configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SDO/VFAULT) | Serial Data Output / Voltage Short-Fault Alert | In software mode: reads back register data on SCLK rising edge; in hardware mode: open-drain fault alert asserted low on VOUT short |
| 3 (CLEAR) | Asynchronous Clear Input | Active-high signal forcing output to zero-scale (unipolar) or midscale (bipolar) - used for safe startup or emergency shutdown |
| 6 (SYNC/RSET) | Register Latch / External RSET Select | In software mode: rising edge clocks 24-bit data into registers; in hardware mode: selects internal/external current sense resistor |
| 7 (SCLK/OUTEN) | Serial Clock Input / Output Enable | In software mode: falling-edge clocked interface up to 50 MHz; in hardware mode: enables/disables output drivers |
| 18 (IOUT) | Current Output Terminal | Drives 4–24 mA loops with open-circuit fault detection and compliance up to AVDD − 2.75 V |
| 23 (VOUT) | Voltage Output Terminal | Delivers buffered 0–10 V or ±10 V outputs with short-circuit protection and 0.12 Ω DC impedance |
| 29 (HW SELECT) | Mode Configuration Input | Low = software control (SPI); high = hardware control (R0–R3 pins set range) - determines pin function mapping |
| 31 (FAULT/TEMP) | Fault Alert / Overtemperature Output | In software mode: open-drain general fault flag (open/short/PEC/overtemp); requires external pull-up |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Output Ranges | Five current and four voltage ranges configured via SPI - eliminates hardware rework when changing field device types |
| On-Chip Fault Detection | Detects open-circuit (IOUT), short-circuit (VOUT), overtemperature, and PEC errors - reduces need for external supervision circuitry |
| Flexible Power-Up State | Configurable to 0 V or high-impedance tristate via CLEAR pin level - prevents transient output during system boot |
| Overrange Capability | 20% voltage overrange (e.g., 0–12 V on 0–10 V setting) and 2% current overrange - accommodates sensor headroom and calibration margins |
| Galvanic Isolation Support | 3-wire SPI interface with optional PEC and 50 MHz clock - minimizes isolation component count in reinforced-isolated PLC designs |
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; lower current TUE (±0.02% FSR) but no ±24 mA range | Better suited for non-isolated, high-voltage loop-powered systems where negative supply is unavailable | Select AD5751 when simplifying power architecture outweighs need for bipolar 24 mA output |
| AD5420 | 16-bit resolution, only 4–20 mA current output (no voltage output or bipolar ranges); higher gain error (±0.1% FSR) | Targeted at cost-sensitive, current-only applications like basic transmitter interfaces | Choose AD5420 only when voltage output and programmable bipolar ranges are unnecessary |
Compared with AD5750-2BCPZ, AD5751 eliminates the negative supply but sacrifices ±24 mA capability and dual-rail noise immunity, while AD5420 reduces feature set and accuracy to meet entry-level current-loop requirements - neither offers identical dual-mode programmability and comprehensive fault coverage.

FAQ
What is the reference voltage requirement for AD5750-2BCPZ?
The AD5750-2BCPZ requires a precise 2.5 V external reference applied to the VREF pin. This value is fixed per the AD5750-2 variant and must be maintained within tight tolerance; deviation introduces proportional output error. The device buffers this reference internally for VIN scaling and current/voltage range generation, and leakage is specified at ±1 µA.
How does AD5750-2BCPZ handle output faults?
The AD5750-2BCPZ provides integrated fault detection: VOUT short-circuit triggers VFAULT (Pin 1), IOUT open-circuit asserts IFAULT (Pin 32 in hardware mode), and overtemperature activates TEMP (Pin 31). In software mode, FAULT/TEMP (Pin 31) serves as a combined open-drain alert for all faults. All fault pins require external pull-up resistors and assert low on error condition.
Can AD5750-2BCPZ drive inductive loads?
Yes, AD5750-2BCPZ can drive inductive loads up to 0.1 H, but requires external compensation. For inductive loads, a capacitor must be placed between COMP1 (Pin 19) and COMP2 (Pin 20) to stabilize the voltage output buffer and prevent oscillation. The datasheet provides design guidelines for selecting this capacitor based on load inductance and desired settling time.
What is the role of the HW SELECT pin on AD5750-2BCPZ?
The HW SELECT pin (Pin 29) configures AD5750-2BCPZ into software mode (HW SELECT = 0) or hardware mode (HW SELECT = 1). In software mode, all configuration is done via SPI; in hardware mode, output ranges are selected by logic levels on R0–R3 pins (SDIN, AD2, AD1, AD0), and SYNC/RSET becomes RSET select. Mode selection is latched at power-up and cannot be changed dynamically.
Does AD5750-2BCPZ support overrange operation, and how is it enabled?
Yes, AD5750-2BCPZ supports programmable overrange: voltage outputs offer up to 20% overrange (e.g., 0–12 V on 0–10 V setting), and unipolar current ranges support 2% overrange (e.g., 4–20.4 mA). Overrange is enabled via dedicated bits in the configuration register during software mode operation and is active only when the corresponding range is selected - no external components are needed.
