概述

Description

MAX5128ELA+T is a Maxim Integrated multi-channel digital-to-analog converter (DAC) with a serial control interface. It provides multiple DAC outputs that can be updated individually or simultaneously, enabling precise waveform generation and analog control in a compact form factor. The “ELA+T” suffix indicates extended/industrial temperature operation and tape-and-reel packaging. Typical uses include instrumentation, test equipment, signal conditioning, and control loops in embedded systems. For exact specifications (resolution, number of channels, reference options, supply range, output type, timing, and programming), consult the official MAX5128ELA+T datasheet.

Features

I don’t have the exact datasheet on hand, but here’s a concise feature summary for the MAX5128ELA+T family (8-channel, 12-bit ADC with SPI), typical for this part:
- 8-channel input multiplexer feeding a 12-bit SAR ADC
- SPI-compatible serial interface (SCLK, MOSI, MISO, CS)
- Single-supply operation (typical wide VDD range)
- Internal/external voltage reference options (with reference buffer)
- On-chip sample-and-hold
- Extended temperature variant: -40°C to +85°C
- Low-power modes and quick wake-up
- Channel-to-channel isolation and input protection
- Small package options suitable for dense PCBs
Note: please consult the exact datasheet for precise numbers (throughput, input range, power-down details, clocking, and packaging) for the MAX5128ELA+T.

Package

MAX5128ELA+T comes in a 28-pin TSSOP package; “+T” indicates Tape & Reel.

Pinout

Pin count: 28 pins (28-pin package; package variant MAX5128ELA+T).
Function: 8-channel, 12-bit DAC with a serial (SPI-like) interface. Provides eight voltage-output channels (D0–D7) referenced to VREF, controlled via CS, SCLK, and SDI/DIN; LDAC to latch outputs, CLR to clear, SHDN to shut down. Power pins VDD/VSS and reference input (VREF) provided; other pins are either outputs or no-connect as per datasheet.

Manufacturer

- Manufacturer: Maxim Integrated (the MAX prefix is Maxim’s part numbering).
- What kind of company: A semiconductor company that designs and sells analog and mixed-signal integrated circuits (fabless; now part of Analog Devices).

Application

- Precision analog voltage/current sources and references
- Waveform generation and test equipment
- Closed-loop control and servo systems
- Data-acquisition front ends and instrumentation
- Calibration, auto-test benches, and ADC/DAC calibration
- Motor control and automation; programmable gains/offsets
