Product details
Overview
AD5750-2BCPZ-RL7 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 ±24 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 AD5750-2BCPZ-RL7 datasheet, AD5750-2BCPZ-RL7 pinout, AD5750-2BCPZ-RL7 application, or AD5750-2BCPZ-RL7 equivalent, this page provides verified functional identity, validated SPI/MICROWIRE interface behavior, confirmed 32-lead LFCSP package mapping, real-world fault detection implementation details, and precise range configuration logic for PLC analog output modules.
Technical Context
The AD5750-2BCPZ-RL7 implements dual-path analog output architecture: a current output stage with internal/external RSET selection and a separate buffered voltage output stage with overrange capability. Its digital interface uses SPI/MICROWIRE-compatible 3-wire serial protocol with optional CRC-8 packet error checking (PEC) and asynchronous CLEAR for zero-scale/midscale reset.
Hardware/software mode selection is controlled by the HW SELECT pin, determining whether range configuration occurs via register writes (software mode) or parallel pin strapping (hardware mode). Output fault detection includes open-circuit (IFAULT), short-circuit (VFAULT), and overtemperature (TEMP) alerts, each mapped to dedicated open-drain pins with pull-up requirements.

Pinout & Package
AD5750-2BCPZ-RL7 uses a 32-lead, 5 mm × 5 mm LFCSP package with exposed paddle electrically connected to AVSS. Pin functions are mode-dependent: software mode uses SDIN/SCLK/SYNC for SPI control and SDO/VFAULT for readback/fault reporting; hardware mode repurposes pins like R0–R3 as range decode inputs and RSET as internal/external resistor select.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SDO/VFAULT) | Serial Data Output / Voltage Short-Fault Alert | In software mode: CMOS SDO for register readback; in hardware mode: open-drain VFAULT asserted low on VOUT short |
| 3 (CLEAR) | Asynchronous Clear Input | Active-high signal forcing IOUT/VOUT to zero-scale (unipolar) or midscale (bipolar); determines power-on state of VOUT channel |
| 6 (SYNC/RSET) | Register Latch / Current Sense Resistor Select | In software mode: rising-edge SYNC loads 24-bit register; in hardware mode: logic level selects internal (RSET=1) or external (RSET=0) RSET |
| 7 (SCLK/OUTEN) | Serial Clock / Output Enable | In software mode: falling-edge clock for SDIN data; in hardware mode: active-high OUTEN enabling/disabling analog outputs |
| 18 (IOUT) | Current Output Terminal | Drives 4–20 mA loop with compliance up to AVDD − 2.75 V; supports capacitive loads ≤1 µF and inductive loads ≤0.1 H |
| 23 (VOUT) | Voltage Output Terminal | Buffered 0–10 V output with 0.12 Ω DC impedance; requires COMP1/COMP2 compensation for >220 pF loads |
| 29 (HW SELECT) | Mode Configuration Input | Logic low = software mode (SPI control); logic high = hardware mode (pin-strapped range selection) |
| 31 (FAULT/TEMP) | Fault Alert / Overtemperature Indicator | In software mode: open-drain FAULT asserted low on open-circuit, short-circuit, overtemp, or PEC error; in hardware mode: TEMP only |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Output Ranges | Five current and four voltage ranges selectable via SPI registers or hardware pins - eliminates need for external gain/offset trimming in multi-range I/O modules |
| On-Chip Fault Detection | Dedicated open-drain FAULT, VFAULT, IFAULT, and TEMP pins with independent assertion logic - enables immediate loop diagnostics without host processor intervention |
| Packet Error Checking (PEC) | CRC-8 checksum appended to SPI write commands - prevents undetected corruption of range or calibration settings in noisy factory-floor environments |
| Flexible Power-Up State | CLEAR pin level determines VOUT startup condition: 0 V (active-low CLEAR) or tristate (active-high CLEAR) - avoids transient injection during system boot |
| Inductive/Capacitive Load Drive | Stable operation into 0.1 H inductors and 1 µF capacitors with external COMP1/COMP2 compensation - supports long cable runs and solenoid actuator interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar industrial analog output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5751ACPZ-REEL7 | Single-supply operation (up to +55 V AVDD), no AVSS rail required; identical SPI interface and range programming but lacks hardware mode pins. | Better suited for battery-powered or single-rail systems; not drop-in compatible due to missing AVSS and different pinout. | Select AD5751 when board space is constrained and ±12 V/±24 V dual supply is unavailable. |
| AD5422ACPZ-REEL7 | Integrated 16-bit DAC core, higher resolution (16-bit vs. 12-bit effective), but fixed 4–20 mA range and no voltage output channel. | Used where high-resolution current sourcing is primary requirement and voltage output is unnecessary. | Choose AD5422 for applications demanding <0.0015% INL and embedded DAC functionality, accepting loss of voltage output flexibility. |
Compared with AD5750-2BCPZ-RL7, AD5751 offers supply simplification at the cost of hardware configurability, while AD5422 trades dual-output versatility for higher current resolution and integrated DAC architecture-neither is pin-compatible, requiring PCB redesign.

FAQ
What output ranges does the AD5750-2BCPZ-RL7 support?
The AD5750-2BCPZ-RL7 supports five current output ranges: 4 mA to 20 mA, 0 mA to 20 mA, 0 mA to 24 mA, ±20 mA, and ±24 mA. For voltage, it provides 0 V to 5 V, 0 V to 10 V, ±5 V, and ±10 V, all with programmable 20% overrange. These ranges are selected either via SPI register writes (software mode) or hardware pin strapping (hardware mode), and the AD5750-2BCPZ-RL7 datasheet confirms all ranges operate across −40°C to +105°C.
How does the AD5750-2BCPZ-RL7 handle fault conditions?
The AD5750-2BCPZ-RL7 integrates multiple independent fault detection circuits: open-circuit (IFAULT), voltage short-circuit (VFAULT), general fault alert (FAULT), and overtemperature (TEMP). In software mode, FAULT pin asserts low on any detected fault; VFAULT and IFAULT are dedicated pins. All fault outputs are open-drain and require external pull-up resistors. The AD5750-2BCPZ-RL7 also supports packet error checking (PEC) to detect corrupted SPI commands, ensuring reliable operation in electrically noisy industrial settings.
Is the AD5750-2BCPZ-RL7 compatible with standard SPI interfaces?
Yes, the AD5750-2BCPZ-RL7 features a fully SPI- and MICROWIRE™-compatible serial interface operating in 3-wire mode (SDIN, SCLK, SYNC) with support for up to 50 MHz clock rates. It accepts 24-bit frame formats for register writes and supports readback via SDO. Optional CRC-8 packet error checking (PEC) enhances reliability. The AD5750-2BCPZ-RL7 timing specifications (e.g., t1 = 20 ns min SCLK cycle time) confirm compatibility with standard microcontroller SPI peripherals without custom timing adjustments.
What is the role of the HW SELECT pin on the AD5750-2BCPZ-RL7?
The HW SELECT pin configures the AD5750-2BCPZ-RL7 between software mode (HW SELECT = 0) and hardware mode (HW SELECT = 1). In software mode, output ranges and functions are set via SPI register writes; in hardware mode, pins R0–R3 directly encode range selection, and RSET selects internal/external current sense resistor. This dual-mode architecture allows the same AD5750-2BCPZ-RL7 device to serve both firmware-flexible and jumper-configurable designs without hardware change.
Does the AD5750-2BCPZ-RL7 require external components for stable operation?
Yes, the AD5750-2BCPZ-RL7 requires external components for optimal performance: a 15 kΩ resistor between REXT1/REXT2 improves current output temperature drift; pull-up resistors on open-drain fault pins (e.g., FAULT, VFAULT) are mandatory; and compensation capacitors between COMP1/COMP2 are needed for driving capacitive loads >220 pF. The AD5750-2BCPZ-RL7 datasheet specifies exact values and placement guidelines to ensure stability with inductive (≤0.1 H) and capacitive (≤1 µF) loads.
