LTC1296BCN#PBF

ADCs/DACs - Special Purpose Overview

The LTC1296BCN#PBF is a single-chip 12-bit data acquisition system manufactured by Analog Devices Inc. It integrates a successive approximation A/D converter, an analog multiplexer, and a sample-and-hold circuit using LTCMOS switched capacitor technology. The device supports eight differential or single-ended input channels and operates on a single +5V supply. It features a serial interface compatible with most microprocessor ports, allowing data transmission over three to four wires. Key specifications include a maximum throughput rate of 46.5 kS/s, a conversion time of 12µs, and a supply current of 6.0mA. The component is housed in a 20-lead PDIP package.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 12-bit SAR ADC with built-in sample and hold for all single-ended inputs
• Software-programmable unipolar/bipolar conversion and differential/single-ended input configuration
• Serial I/O interface requiring only three to four wires for communication with MPU ports
• System Shutdown Output (SSO) pin for powering down external signal conditioning circuitry

ADCs/DACs - Special Purpose Applications

• 12-bit data acquisition systems with power shutdown capabilities
• Strain gauge bridge measurements
• Industrial process control monitoring
• Battery-powered instrumentation

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm package type and temperature range. The BCN suffix indicates a commercial grade device in a 20-lead PDIP package. Ensure compatibility with the intended operating temperature range of 0°C to 70°C for this specific variant.

ADCs/DACs - Special Purpose Selection Notes

Select the LTC1296BCN#PBF when eight input channels are required with a 12-bit resolution and low power consumption. This model is suitable for applications needing a system shutdown output to manage peripheral power. Compare with the LTC1293 and LTC1294 if fewer channels or different interface requirements are needed.

ADCs/DACs - Special Purpose Part Context

The LTC1296 is part of the LTC1293/4/6 family of single-chip 12-bit data acquisition systems. While sharing core ADC functionality, the LTC1296 distinguishes itself by providing eight input channels and a dedicated System Shutdown Output pin. Other family members like the LTC1293 offer six channels without the SSO feature.
