概述

Description

The AD5541LRZ is Analog Devices’ 12-bit multiplying DAC (MDAC) with a current output. It accepts a serial digital input (SPI-compatible) and converts it into a proportional output current, which is typically converted to a voltage with an external precision op-amp. Being a multiplying DAC, the full-scale current scales with the external reference, enabling flexible 0-to-IFS ranges. Key benefits include monotonicity, good linearity, low glitch energy, and low power—suitable for precision control, waveform generation, and programmable gain applications. It requires an external reference and an output amplifier (the DAC provides Iout; Vout is generated externally). Interface includes DIN/SDI, SCLK, and CS/LDAC (depending on variant), plus Vref, Iout, GND, and V+. The LRZ suffix denotes a specific RoHS-compliant package variant. For exact specs (resolution, settling time, temperature range, supply range) and pinout, consult the AD5541 data sheet.

Features

AD5541LRZ features (concise):
- 12-bit multiplying DAC
- Serial (SPI-compatible) input interface
- External reference input for full-scale control
- Monotonic with good DNL/INL performance
- Fast settling and low glitch energy
- Low power CMOS design
- Wide operating supply range and temperature performance
- Small, RoHS-compliant packaging (LRZ) with Pb-free process

Package

AD5541LRZ comes in an 8-lead MSOP (MSOP-8) package; Pb-free/RoHS-compliant.

Pinout

- Pin count: 14 pins (SOIC-14/PDIP-14, lead-free LRZ variant).
- Function: 12-bit multiplying DAC with SPI-compatible serial input. It is a current-output DAC that requires an external op-amp (to convert to voltage) and an external reference to scale the output.

Manufacturer

The AD5541LRZ is manufactured by Analog Devices, Inc. (ADI). ADI is a global American semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing ICs, including data converters, amplifiers, sensors, and related solutions. Headquartered in Norwood, Massachusetts, ADI is a leading supplier of precision signal-processing ICs for various industries.

Application

AD5541LRZ is a 12-bit multiplying DAC. Typical applications include:
- Programmable gain/offset in instrumentation and control loops
- Waveform generation and analog computation
- DAC-based calibration and reference generation
- Precision programmable current/voltage sources for ATE/test equipment
- Sensor interfacing and data-acquisition front ends
- Analog control in process control and servo systems
