概述

Description

MAX5424ETA is a Maxim Integrated (now Analog Devices) quad, 12-bit digital-to-analog converter (DAC) with a serial interface. It provides four independent voltage-output channels programmed over an SPI-like bus from a microcontroller. The device supports an external reference, buffered outputs, and practical power-down modes, making it suitable for precision control, waveform generation, and programmable voltage references in instrumentation and embedded systems. The ETA suffix denotes a specific RoHS-compliant package variant. For exact electrical specs, timing, pinout, and operating ranges, consult the MAX5424 datasheet.

Features

Here are the typical features of the MAX5424ETA:
- Quad, 12-bit voltage-output DAC
- SPI-compatible serial interface (SCLK, DIN, CS) with LDAC for simultaneous updates
- Wide supply range: 2.7 V to 5.5 V
- Output range typically 0 to Vref; Vref+ external reference (Vref− to GND)
- 1 LSB equals Vref/4096
- Monotonic output over full code range
- Output buffers for low output impedance drive
- Optional internal/external reference depending on variant
- Fast settling time and low glitch energy on updates
- Power-down mode for reduced current consumption
- 16-pin package (RoHS, variant forms)
Note: exact reference options and package variants may vary by device revision; check the specific MAX5424ETA datasheet for definitive specs.

Package

MAX5424ETA is the 16-pin TQFP package version of the MAX5424 (lead-free/rohs). Always verify in the datasheet for the exact packaging option.

Pinout

Pin count: 28 pins (ETA package).
Function: MAX5424ETA is a quad, serial-input (SPI-like) 12-bit digital-to-analog converter with four voltage-output channels (VOUT1–VOUT4). It provides a four-channel DAC with a reference input (VREF) and standard power/ground pins (VDD, DGND/AGND, etc.), plus control pins (CS, SCLK, SDI, LDAC).

Manufacturer

Manufacturer: Maxim Integrated (MAXIM).
What kind of company: A global fabless semiconductor company that designs and markets analog and mixed-signal integrated circuits (now part of Analog Devices since 2021).

Application

Typical applications for MAX5424ETA include:
- Industrial automation and process control
- Data acquisition and instrumentation systems
- Medical instrumentation and laboratory test equipment
- Servo/motor control and closed-loop feedback
- Programmable precision voltage/current sources and waveform generation
- Calibration, test and measurement gear
- Embedded systems requiring accurate analog outputs
