LTC1093CSW#TRPBF

ADCs/DACs - Special Purpose Overview

The LTC1093CSW#TRPBF is a 6-channel, 10-bit serial I/O data acquisition system manufactured by Analog Devices Inc. It integrates a switched-capacitor successive approximation A/D converter, an analog multiplexer, and on-chip sample-and-holds. The device supports unipolar or bipolar conversion modes and differential or single-ended input configurations via software control. It operates on a single 5V supply or dual supplies (e.g., +5V/-5V). Key electrical specifications include a maximum positive supply current of 2.5mA, a typical offset error of -0.5LSB, and a total unadjusted error of -1LSB for the A grade. The component utilizes a synchronous half-duplex serial interface compatible with standard microprocessor ports.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 6-channel analog multiplexer with software-configurable single-ended or differential inputs
• 10-bit resolution with low power consumption (2.5mA max at 5V)
• Direct serial interface to MPU using CS, CLK, DIN, and DOUT pins
• On-chip sample-and-hold circuitry with fast conversion time

ADCs/DACs - Special Purpose Applications

• Remote data acquisition systems requiring low power
• Industrial process control monitoring
• Battery-powered instrumentation
• Multi-channel sensor interfacing

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm the A grade specification if strict temperature stability is required. Check for end-of-life status as older ADC families may have limited availability from distributors.

ADCs/DACs - Special Purpose Selection Notes

Select the LTC1093 over the LTC1094 if only six channels are needed to reduce pin count. Ensure the application requires either single-ended or differential inputs, as the LTC1093 supports both via configuration bits. Verify that the microprocessor interface can handle the synchronous serial protocol timing requirements.

ADCs/DACs - Special Purpose Part Context

This component belongs to the LTC109x family of 10-bit data acquisition systems, which also includes the 2-channel LTC1091, 1-channel LTC1092, and 8-channel LTC1094. The 'SW' in the part number denotes the 16-lead Plastic SO Wide package. These devices are designed as drop-in replacements for older parallel ADCs in many legacy designs.

ADCs/DACs - Special Purpose Replacement Considerations

The LTC1094 is a pin-compatible alternative offering 8 channels instead of 6. For single-channel applications, the LTC1092 serves as a simpler alternative. No direct modern equivalents with identical functionality are listed in the provided documentation.
