LTC1296BCSW#PBF

ADCs/DACs - Special Purpose Overview

The LTC1296BCSW#PBF is a single-chip 12-bit data acquisition system manufactured by Analog Devices Inc. It integrates an 8-channel analog multiplexer, a built-in sample and hold circuit, and a successive approximation register (SAR) analog-to-digital converter. The device operates on a single +5V supply or dual ±5V supplies, achieving a maximum throughput rate of 46.5ksps with a conversion time of 12µs. It features software-programmable unipolar/bipolar conversion modes and differential/single-ended input configurations via a synchronous serial interface.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 8-channel multiplexer with built-in sample and hold for all single-ended inputs
• Software-configurable unipolar or bipolar conversion modes
• Dedicated System Shutdown Output (SSO) pin to power down external signal conditioning circuitry
• Direct interface capability to most microprocessor serial ports and parallel I/O ports

ADCs/DACs - Special Purpose Applications

• 12-bit data acquisition systems requiring power management
• Strain gauge bridge measurements
• Industrial process control monitoring
• Portable instrumentation powered by single supplies

ADCs/DACs - Special Purpose Procurement Notes

Verify the package type is 20-lead Plastic SO Wide (SW) and the temperature grade is Commercial (BC). Confirm RoHS compliance status through official manufacturer documentation as local distributor listings may vary. Ensure the ordering suffix matches the specific lead-free and halogen-free requirements of the target assembly process.

ADCs/DACs - Special Purpose Selection Notes

Select this model over the LTC1293 or LTC1294 variants specifically when the System Shutdown Output (SSO) feature is required to manage external peripheral power. The 'BC' suffix indicates a commercial temperature range of 0°C to 70°C; choose the 'BI' suffix if operation in the industrial range of -40°C to 85°C is necessary. Verify that the 46.5ksps throughput meets the application's sampling requirements.

ADCs/DACs - Special Purpose Part Context

This component belongs to the LTC1293/4/6 family of single-chip 12-bit data acquisition systems. While the LTC1293 lacks an internal reference and the LTC1294 adds one, the LTC1296 distinguishes itself by including the SSO pin for external power control. All three share identical core ADC performance, resolution, and multiplexer architecture.
