Analog Devices Inc. AD5750-1BCPZ

Overview

AD5750-1BCPZ 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 (0 V to 10 V, ±10 V, etc.) with 20% overrange, ±0.03% FSR TUE for current, ±0.02% FSR TUE for voltage, and operates from −40°C to +105°C in a 32-lead 5 mm × 5 mm LFCSP package - deployed in PLC analog output modules.

For engineers reviewing the AD5750-1BCPZ datasheet, AD5750-1BCPZ pinout, AD5750-1BCPZ application, or AD5750-1BCPZ equivalent, key selection criteria include programmable unipolar/bipolar I/V ranges, on-chip fault detection (open/short-circuit), SPI/MICROWIRE interface with CRC-8 PEC, ±12 V to ±24 V dual supply operation, and compliance to AVDD − 2.75 V loop headroom.

Technical Context

The AD5750-1BCPZ implements a dual-path analog output architecture: one path conditions buffered VIN (0 V to 2.5 V) for precision current output via internal or external RSET, while the other routes scaled voltage to VOUT with independent short-circuit protection. Its hardware/software mode selection (via HW SELECT pin) determines whether range configuration is set by digital registers or discrete logic levels on R0–R3.

It integrates real-time fault monitoring - including open-circuit (IFAULT), short-circuit (VFAULT), and overtemperature (TEMP) alerts - with asynchronous CLEAR for zero/midscale reset and power-on-reset ensuring known startup state (0 V or tristate). The device uses a dedicated VSENSE+ and VSENSE− pair for Kelvin sensing of voltage load connections, enabling accurate regulation under varying cable drop.

Key Specifications

Pinout & Package

AD5750-1BCPZ is housed in a 32-lead, 5 mm × 5 mm LFCSP package with exposed paddle tied to AVSS. Pin functions are mode-dependent (software/hardware), with shared pins like SDO/VFAULT and FAULT/TEMP serving dual roles based on HW SELECT state.

FAQ

What is the input voltage range for AD5750-1BCPZ?

The AD5750-1BCPZ accepts a buffered analog input (VIN) of 0 V to 2.5 V - optimized for interfacing with low-voltage, single-supply DACs such as the AD5662. This range differs from the AD5750 (0 V to 4.096 V) and AD5750-2 (0 V to 2.5 V), confirming AD5750-1BCPZ's specific role in cost-sensitive, 2.5 V reference-based systems. The input leakage current is tightly controlled at ±1 µA.

Does AD5750-1BCPZ support both current and voltage outputs simultaneously?

No - the AD5750-1BCPZ provides either current output (IOUT pin) or voltage output (VOUT pin) at any given time, not concurrently. Its architecture separates the two paths: current output uses internal/external RSET and IOUT, while voltage output uses the dedicated VOUT buffer with Kelvin sensing (VSENSE+/VSENSE−). Both cannot be active simultaneously due to shared bias structures and fault-monitoring logic.

How does the HW SELECT pin affect AD5750-1BCPZ operation?

The HW SELECT pin configures AD5750-1BCPZ into hardware mode (logic high) or software mode (logic low). In software mode, all functions - including output range, fault behavior, and overrange - are controlled via SPI registers. In hardware mode, range selection is determined by R0–R3 pin states, and features like PEC and register readback are disabled. This dual-mode capability supports both firmware-flexible and pin-strapped deployments.

What fault conditions does AD5750-1BCPZ detect and report?

The AD5750-1BCPZ detects and reports three primary fault conditions: open-circuit on IOUT (via IFAULT in hardware mode or FAULT/TEMP in software mode), short-circuit on VOUT (via VFAULT), and overtemperature (via FAULT/TEMP or NC/IFAULT depending on mode). All fault alerts are open-drain outputs requiring external pull-up resistors and assert low upon detection - enabling immediate system-level response without polling.

Can AD5750-1BCPZ drive inductive loads like solenoid valves?

Yes - the AD5750-1BCPZ is rated to drive inductive loads up to 0.1 H, with built-in protection against flyback voltage transients. When driving such loads, proper external compensation (e.g., snubber networks or clamping diodes) is required, and the COMP1/COMP2 pins may be used to stabilize the VOUT buffer if capacitive loading exceeds 1 nF. The current output stage includes slew-rate limiting to suppress ringing during step transitions.
