LTC1293BCSW#TRPBF

ADCs/DACs - Special Purpose Overview

The LTC1293BCSW#TRPBF is a single-chip 12-bit data acquisition system manufactured by Analog Devices Inc. It integrates a successive approximation analog-to-digital converter (ADC), an analog multiplexer, and a built-in sample-and-hold circuit using LTCMOS switched capacitor technology. The device supports six single-ended or differential input channels with a maximum throughput rate of 46.5 kS/s. It operates on a single +5V supply or dual ±5V supplies, consuming 6.0mA of current. The component features a synchronous half-duplex serial interface for direct connection to microprocessor ports.

ADCs/DACs - Special Purpose Feature Summary

• 12-bit resolution SAR ADC with 46.5kHz maximum sampling rate
• Six-channel analog multiplexer supporting single-ended or differential inputs
• Software programmable for unipolar/bipolar conversion and power shutdown
• Direct 4-wire serial interface compatible with most MPU serial ports

ADCs/DACs - Special Purpose Applications

• Industrial process control systems requiring multi-channel data acquisition
• Battery-powered instrumentation utilizing low supply current operation
• Strain gauge bridge measurements with signal conditioning
• Microprocessor-based data logging systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging when sourcing this specific variant. Confirm that the BC grade corresponds to the commercial temperature range of 0°C to 70°C as specified in the datasheet. Ensure compatibility with the 16-lead SOIC-W package dimensions for PCB layout.

ADCs/DACs - Special Purpose Selection Notes

Select the LTC1293BCSW#TRPBF when six input channels are required; the LTC1294 offers eight channels. Consider the LTC1296 if a System Shutdown Output (SSO) pin is needed to control external circuitry. Verify that the 12-bit resolution and 46.5kS/s speed meet the application's accuracy and bandwidth requirements compared to higher-speed alternatives.

ADCs/DACs - Special Purpose Part Context

This component belongs to the LTC1293/4/6 family of single-chip 12-bit data acquisition systems. The LTC1293 specifically provides six channels, distinguishing it from the eight-channel LTC1294 and the LTC1296 which includes a system shutdown output. All variants share the same core ADC architecture and serial interface protocol.

ADCs/DACs - Special Purpose Replacement Considerations

Publicly confirmed substitute part numbers include LTC1293CCSW#PBF and LTC1293DCSW#PBF within the same family. These alternatives differ primarily in temperature grade and package type rather than functional performance.
