概述

Description

The AMC1350QDWVRQ1 is a Texas Instruments isolated delta-sigma converter (front-end) in the AMC1350 family. It provides galvanic isolation between the analog input (such as a shunt for current sensing) and the digital side, enabling precise high-voltage measurements in power, motor control, and industrial apps. It accepts a differential input, delivers high-resolution conversion, and outputs a digital data stream across the isolation barrier to a host microcontroller or DSP via a serial interface. The QDWVRQ1 suffix identifies a specific packaging/variant (lead-free, temperature grade, and related package code) of the AMC1350 product line. For exact specifications (input range, isolation voltage, supply rails, data rate, and interface timing), consult the TI datasheet and product page.

Features

AMC1350QDWVRQ1 features (concise):
- Galvanic isolation between input and output for safety in power electronics
- Single-channel isolated amplifier suitable for sensing voltage/current signals
- Independent input and output supply rails (isolation preserved)
- Fixed gain with high accuracy, low offset, and low drift
- Rail-to-rail output compatible with common ADC ranges
- High common-mode rejection and strong transient immunity (EMI robustness)
- Built-in protection: overvoltage/short-circuit tolerance and ESD robustness
- Industrial temperature range and RoHS compliant
- Small package form factor (compact 16-pin variant) for dense layouts
Note: For exact isolation voltage, supply ranges, gain, accuracy specs, and package details, please refer to the official datasheet.

Package

The AMC1350QDWVRQ1 is supplied in an 8-pin VQFN (DWV) package, automotive-qualified and delivered on tape-and-reel (RQ1). Verify exact mechanical dimensions and thermal specs on the TI datasheet.

Pinout

Pin count: 8 pins (8‑pin QFN package, TI order code QDW).
Function: The AMC1350 is a reinforced‑isolation precision analog amplifier/isolator. The 8 pins split between the primary (input) side—differential input pins (IN+, IN–) plus input supply and ground (VDD1/GND1)—and the isolated secondary (output) side—output pin plus output supply and ground (OUT, VDD2/GND2). It converts a differential low‑voltage input to a galvanically isolated, level‑shifted single‑ended output for isolated voltage/current sensing in industrial and power applications.

Manufacturer

Manufacturer: Texas Instruments (TI).
Type of company: TI is a multinational semiconductor company headquartered in Dallas, Texas, that designs and manufactures analog, mixed-signal and embedded-processor integrated circuits and related components (including automotive-qualified ICs) for industrial, automotive, consumer and communications markets.

Application

Applications of AMC1350QDWVRQ1:
- Isolated high-side voltage and current sensing for motor drives, inverters, and DC-DC converters
- Energy metering and power monitoring
- Automotive power electronics and battery-management systems
- Industrial automation and smart-grid sensing
- Protection and data acquisition in high-voltage systems

Equivalent

Do you mean pin‑for‑pin drop‑in equivalents or functionally similar isolated amplifiers? Also specify required supply voltage, isolation rating, package (WQFN) and automotive grade. With that I can list accurate direct cross‑references (TI family, Analog Devices, Broadcom/Avago equivalents).
