Analog Devices Inc. AD5750-1BCPZ-REEL7

Overview

AD5750-1BCPZ-REEL7 from Analog Devices is a single-channel, precision industrial current/voltage output driver with software-programmable ranges. It supports five current output ranges (including 4 mA to 20 mA and ±20 mA) and four voltage ranges (0 V to 10 V, ±10 V, etc.), delivers ±0.03% FSR total unadjusted error, ±5 ppm/°C typical current drift, and operates from ±12 V to ±24 V supplies across −40°C to +105°C. It is used in PLC analog output modules for process actuator control.

For engineers reviewing the AD5750-1BCPZ-REEL7 datasheet, AD5750-1BCPZ-REEL7 pinout, AD5750-1BCPZ-REEL7 application, or AD5750-1BCPZ-REEL7 equivalent, key selection criteria include programmable I/V range configuration via SPI/MICROWIRE, on-chip fault detection (open/short-circuit), 32-lead LFCSP package compatibility, and support for external RSET resistor to optimize temperature drift.

Technical Context

The AD5750-1BCPZ-REEL7 implements a dual-path analog output architecture: one path conditions buffered VIN (0 V to 2.5 V) for current output using internal or external RSET, and another scales the same input for voltage output via a separate buffer with overrange capability. Its hardware/software mode selection (HW SELECT pin) determines whether range configuration is set by pins (R0–R3) or SPI register writes.

It integrates loop compliance monitoring (up to AVDD − 2.75 V), asynchronous CLEAR for zero/midscale forcing, packet error checking (PEC) with CRC-8, and independent fault reporting via open-drain outputs (VFAULT, FAULT/TEMP, NC/IFAULT). The device powers up in a known state-either 0 V or tristate-based on CLEAR pin level during power-on reset.

Key Specifications

Pinout & Package

AD5750-1BCPZ-REEL7 uses a 32-lead, 5 mm × 5 mm LFCSP package with exposed paddle tied to AVSS. Pin functions are mode-dependent (software/hardware), and all shared pins (e.g., SDO/VFAULT, SDIN/R0) are defined per mode in the datasheet.

FAQ

What is the analog input voltage range supported by AD5750-1BCPZ-REEL7?

The AD5750-1BCPZ-REEL7 accepts a buffered analog input (VIN) of 0 V to 2.5 V, which is internally scaled to generate the selected current or voltage output range. This range is fixed for the AD5750-1 variant and differs from the AD5750 (0 V to 4.096 V) and AD5750-2 (0 V to 2.5 V with different reference requirement). The input leakage current is specified at ±1 µA, ensuring minimal loading on upstream DACs.

Does AD5750-1BCPZ-REEL7 support both current and voltage outputs simultaneously?

Yes, AD5750-1BCPZ-REEL7 provides independent current (IOUT pin) and voltage (VOUT pin) outputs that can be enabled concurrently. The current output drives the loop load, while the voltage output serves as a local reference or auxiliary signal. Both outputs share the same VIN input and are independently configurable for range and fault behavior - enabling dual-mode operation in compact I/O designs.

How does the HW SELECT pin affect AD5750-1BCPZ-REEL7 operation?

The HW SELECT pin configures AD5750-1BCPZ-REEL7 at power-up: logic low selects software mode (SPI-controlled range and function), while logic high selects hardware mode (pin-strapped R0–R3 range selection). In software mode, pins like SDIN/R0 and AD2/R1 serve as serial interface signals; in hardware mode, they become static range decode bits - requiring careful PCB layout to avoid mode conflict.

What fault conditions does AD5750-1BCPZ-REEL7 detect and report?

AD5750-1BCPZ-REEL7 detects and reports open-circuit (on IOUT), short-circuit (on VOUT), overtemperature, and SPI packet error (via PEC). These faults are signaled through dedicated open-drain pins: VFAULT (hardware mode), FAULT/TEMP (software mode), and NC/IFAULT (hardware mode). Each fault pin asserts low and requires an external pull-up resistor for proper logic-level interfacing with host controllers.

Can AD5750-1BCPZ-REEL7 operate with only a single positive supply?

No, AD5750-1BCPZ-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. For single-rail applications, the pin-compatible AD5751 (supports up to +55 V AVDD, no AVSS needed) is the recommended alternative - retaining identical SPI interface, range programming, and fault architecture.
