Analog Devices Inc. AD5750ACPZ-REEL7

Overview

AD5750ACPZ-REEL7 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 −40°C to +105°C operation, and integrates fault detection, PEC, and asynchronous CLEAR-enabling robust 4 mA–20 mA loop and ±10 V analog control in PLC I/O modules.

For engineers reviewing the AD5750ACPZ-REEL7 datasheet, AD5750ACPZ-REEL7 pinout, AD5750ACPZ-REEL7 application, or AD5750ACPZ-REEL7 equivalent, key selection criteria include programmable bipolar/unipolar output ranges, ±5 ppm/°C current drift and ±3 ppm/°C voltage drift, SPI/MICROWIRE-compatible 3-wire interface, open-circuit/short-circuit protection, and 32-lead 5 mm × 5 mm LFCSP packaging for high-density industrial designs.

Technical Context

The AD5750ACPZ-REEL7 implements a dual-path architecture: one path conditions buffered 0 V–4.096 V analog input (VIN) for precision current output via internal/external RSET, while the other routes the same input through scalable voltage output circuitry with overrange capability. Its hardware/software mode selection (HW SELECT pin) determines whether range configuration occurs via SPI register writes or parallel pin strapping.

It features integrated loop compliance monitoring (up to AVDD − 2.75 V), real-time fault detection (open-circuit, short-circuit, overtemperature, PEC CRC-8 errors), and configurable power-up state (0 V or tristate). The device operates from dual ±12 V to ±24 V analog supplies and 2.7 V–5.5 V digital supply, supporting galvanically isolated interfaces with minimal digital isolation requirements.

Key Specifications

Pinout & Package

AD5750ACPZ-REEL7 uses a 32-lead, 5 mm × 5 mm LFCSP package with exposed paddle tied to AVSS. Pin functions are shared between software and hardware modes (e.g., SDIN/R0, AD2/R1), requiring careful mode selection via HW SELECT.

FAQ

What output current ranges does the AD5750ACPZ-REEL7 support?

The AD5750ACPZ-REEL7 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 either via SPI register writes in software mode or through hardware pin strapping (R0–R3) in hardware mode. Each range includes a small overrange margin (2% for unipolar, unspecified for bipolar), and the device guarantees ±0.03% full-scale range total unadjusted error across all ranges.

Does the AD5750ACPZ-REEL7 require an external reference voltage?

Yes, the AD5750ACPZ-REEL7 requires an external precision reference voltage applied to the VREF pin. For the AD5750 variant (which AD5750ACPZ-REEL7 implements), the specified reference is exactly 4.096 V. Deviation from this value introduces direct proportional error in both current and voltage outputs. The reference must be low-noise and stable, as the device's ±0.02% FSR voltage TUE and ±0.03% FSR current TUE assume nominal VREF accuracy and drift performance.

How does the AD5750ACPZ-REEL7 handle fault conditions like open or short circuits?

The AD5750ACPZ-REEL7 integrates dedicated fault detection circuitry. In software mode, the FAULT/TEMP pin asserts low on open-circuit (IOUT), short-circuit (VOUT), overtemperature, or PEC CRC error. In hardware mode, separate pins-VFAULT (short-circuit), IFAULT (open-circuit), and TEMP (overtemperature)-provide discrete alerts. All fault outputs are open-drain and require external pull-up resistors. Fault status is also readable via SPI status register, enabling both hardware interrupt-driven and software-polling diagnostics.

Can the AD5750ACPZ-REEL7 operate from a single positive supply?

No, the AD5750ACPZ-REEL7 requires dual analog supplies: AVDD (+12 V to +24 V) and AVSS (−12 V to −24 V). It does not support single-supply operation. This architecture enables true bipolar voltage outputs (e.g., ±10 V) and symmetric current sourcing/sinking (e.g., ±24 mA). For single-supply alternatives, consider the pin-compatible AD5751ACPZ-REEL7, which operates from +10.8 V to +55 V AVDD only and omits AVSS.

What is the purpose of the HW SELECT pin on the AD5750ACPZ-REEL7?

The HW SELECT pin determines the fundamental configuration mode of the AD5750ACPZ-REEL7 at power-up: logic low configures software mode (SPI-controlled range selection and register access), while logic high enables hardware mode (range selected by R0–R3 pin states, no SPI required). This pin is sampled once during power-on reset and cannot be changed dynamically. Mode selection affects pin functionality (e.g., SDIN/R0, AD2/R1), so PCB layout must align with the chosen mode.
