LTC1290DISW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1290DISW#TRPBF is a single-chip 12-bit data acquisition system manufactured by Analog Devices Inc. It integrates an 8-channel analog multiplexer, a sample-and-hold circuit, and a successive approximation A/D converter. The device supports both unipolar and bipolar conversions with a maximum throughput rate of 50kHz. It operates on a single +5V supply or dual ±5V supplies, drawing 6.0mA during active conversion. The component features a synchronous full-duplex serial interface compatible with industry standards, allowing direct connection to microprocessors. It is housed in a 20-lead SOIC Wide package.

Analog To Digital Converters (ADC) Feature Summary

• Built-in sample-and-hold for all single-ended channels
• Direct four-wire serial interface to MPU ports
• Power shutdown capability for low power applications

Analog To Digital Converters (ADC) Applications

• Data acquisition systems requiring multi-channel signal processing
• Industrial control systems utilizing serial communication protocols
• Precision measurement instruments needing 12-bit resolution
• Microprocessor-based monitoring systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #TRPBF indicates lead-free tape and reel packaging. Confirm the temperature grade 'D' corresponds to the -40°C to 85°C operating range required for the application. Ensure compatibility with the 20-SOIC (0.295 inch width) footprint during PCB layout. Check for RoHS3 compliance status as indicated in official documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an integrated solution combining multiplexing, sampling, and 12-bit conversion is needed. It is suitable for designs requiring up to 50kHz sampling rates. Consider the serial interface requirements; it supports MSB or LSB first data sequences. Verify that the input voltage range matches the selected unipolar or bipolar configuration relative to the reference voltage.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1290 family of single-chip data acquisition systems. The 'DISW' designation specifies the DC temperature grade (-40°C to 85°C) and the SW package (20-Lead Plastic SO Wide). The '#TRPBF' suffix denotes Tape and Reel packaging with Lead-Free finish. Other variants include PDIP and Ceramic DIP packages with different temperature grades.

Analog To Digital Converters (ADC) Replacement Considerations

LTC1290BISW#TRPBF and LTC1290CISW#TRPBF are parameter-equivalent alternatives within the same package and packaging type, differing primarily in temperature grade specifications.
