LTC1293CCSW#TRPBF

ADCs/DACs - Special Purpose Overview

The LTC1293CCSW#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 sample-and-hold circuit using LTCMOS switched capacitor technology. The device supports six input channels configured for single-ended or differential inputs. It operates on a single +5V supply or dual ±5V supplies with a maximum throughput rate of 46.5ksps. The component utilizes a synchronous half-duplex serial interface compatible with most microprocessor ports.

ADCs/DACs - Special Purpose Feature Summary

• 12-bit resolution SAR ADC with integrated sample-and-hold
• Six-channel analog multiplexer supporting single-ended or differential configurations
• Software programmable unipolar/bipolar conversion modes
• Direct interface to MPU serial/parallel ports via 4-wire synchronous serial I/O

ADCs/DACs - Special Purpose Applications

• Industrial process control systems requiring multi-channel data acquisition
• Battery-powered instrumentation utilizing low power shutdown features
• Data logging systems interfacing with microprocessors
• Strain gauge bridge measurements in sensor interfaces

ADCs/DACs - Special Purpose Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging suitable for automated assembly. Confirm the CC temperature grade covers the required operational range of 0°C to 70°C. Ensure the SOIC-16 package dimensions match the target PCB footprint. Cross-reference the specific lot date code against project requirements if long-term availability is critical.

ADCs/DACs - Special Purpose Selection Notes

Select this model over the LTC1294 when only six input channels are required. Choose the SW package for surface mount applications instead of the PDIP variant. Consider the LTC1296 if a System Shutdown Output pin is needed to control external signal conditioning circuitry. Verify that the 46.5ksps sampling rate meets the bandwidth requirements of the application signals.

ADCs/DACs - Special Purpose Part Context

This component belongs to the LTC1293/LTC1294/LTC1296 family of 12-bit data acquisition systems. The LTC1293 specifically provides six channels, whereas the LTC1294 offers eight channels. The CC suffix denotes commercial temperature performance. The TRPBF designation confirms lead-free status and tape-and-reel shipping format.

ADCs/DACs - Special Purpose Replacement Considerations

The LTC1293BCSW#TRPBF serves as a direct functional replacement within the same family, differing primarily in the B-grade temperature specification compared to the C-grade.
