概述

Description

MAX5418PETA+T is a Maxim Integrated 16‑bit, serial‑input, voltage‑output digital‑to‑analog converter (DAC). It converts a 16‑bit digital word delivered over an SPI‑like interface into an analog voltage, suitable for precision attenuation, calibration, and control in instrumentation and embedded systems. Key ideas: 16‑bit resolution, monotonic operation, fast settling with low glitch, and configurable reference/output options (variant dependent). The PETA+T suffix denotes packaging/shipping options (typically RoHS‑compliant, tape‑and‑reel). For exact specs—reference type, output range, settling time, INL/DNL, and supply requirements—consult the official MAX5418PETA+T data sheet.

Features

Here are typical features of MAX5418PETA+T (datasheet should be consulted for exact specs):
- Quad 12-bit voltage-output DAC
- SPI-compatible serial interface (DIN, SCLK, CS) with LDAC for simultaneous updates
- Unipolar output range: Vout per channel ranges 0–Vref (external reference option)
- On-chip output buffers; monotonic and low-glitch performance
- Internal/external reference options
- Single-supply operation (roughly 2.7V to 5.5V) with SHDN for power-down
- Low power consumption and good dynamic performance
- Temperature range: typical -40°C to +85°C
- Packaging: lead-free, tape-and-reel option PETA+T, 28-pin TSSOP (or similar)
Note: exact numbers (VREF range, current, update rate, INL/DNL, etc.) vary by revision. Please verify against the official datasheet for MAX5418PETA+T.

Package

MAX5418PETA+T comes in a 28-pin plastic TQFP package, Pb-free (RoHS) and supplied in Tape & Reel (T) packaging.

Pinout

Pin count: 28 pins (PETA package).
Function: MAX5418PETA+T is an 8-channel, 12-bit multiplying digital-to-analog converter (MDAC) with an SPI-compatible serial interface and eight buffered voltage outputs. It requires an external reference and provides control pins such as CS, SCK, DIN (serial data), LDAC/CLR/SHDN as applicable.

Manufacturer

Manufacturer: Maxim Integrated Products (MAXIM).
What kind of company: A fabless semiconductor company that designs and markets analog and mixed-signal integrated circuits; Maxim was acquired by Analog Devices in 2021 and its products are now under Analog Devices.

Application

Applications include:
- Data acquisition and instrumentation systems
- Precision waveform generation and signal synthesis
- Automatic test equipment (ATE) and calibration
- Industrial/process control and motor control
- Medical instrumentation and diagnostic equipment
- Test and measurement in audio/telecom equipment

Equivalent

There isn’t an exact one‑to‑one cross reference for MAX5418PETA+T. It’s an 8‑channel, 12‑bit, voltage‑output DAC with a serial interface. For substitutes, search for other vendors’ 8‑channel, 12‑bit SPI DACs, such as Analog Devices AD566x/AD56xx8 family and TI DAC8x/DAC858x series, or Linear Technology LTC26xx/LTC26xx families. Always verify channel count, interface, output range, reference requirements, timing, and package/pinout. Use Maxim’s cross‑reference tool or distributor BOM searches for exact compatible parts.
