LTC1296DIN#PBF

ADCs/DACs - Special Purpose Overview

The LTC1296DIN#PBF is a single-chip 12-bit data acquisition system manufactured by Analog Devices Inc. It integrates a successive approximation analog-to-digital converter, an eight-channel analog multiplexer, and a built-in sample-and-hold circuit. The device operates on a single +5V supply or dual ±5V supplies, consuming 6.0mA of current. It supports a maximum throughput rate of 46.5ksps with a conversion time of 12µs. The component features a serial interface compatible with most microprocessor ports and includes a System Shutdown Output (SSO) pin for power management.

ADCs/DACs - Special Purpose Feature Summary

• 12-bit SAR ADC with 8-channel multiplexer and built-in sample-and-hold
• Software programmable unipolar/bipolar conversion and differential/single-ended inputs
• System Shutdown Output (SSO) pin to control external circuitry power
• Direct 4-wire serial interface to MPU ports with MSB-first or LSB-first data sequence

ADCs/DACs - Special Purpose Applications

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

ADCs/DACs - Special Purpose Procurement Notes

Verify the package type matches the design requirements, as the DIN suffix indicates a 20-lead PDIP package. Confirm that the industrial temperature range (-40°C to 85°C) aligns with the application environment. Ensure the external reference voltage configuration supports the required input span for both unipolar and bipolar modes.

ADCs/DACs - Special Purpose Selection Notes

Select this component when an integrated solution with an SSO pin is required for power management. Compare channel count and resolution against the LTC1293 (6 channels) and LTC1294 (8 channels, no SSO). Verify that the serial interface timing meets the microprocessor clock speed constraints, specifically the 1MHz maximum clock frequency.

ADCs/DACs - Special Purpose Part Context

The LTC1296 is part of the LTC1293/4/6 family of single-chip 12-bit data acquisition systems. It shares the same core ADC and multiplexer architecture as the LTC1293 and LTC1294 but adds the System Shutdown Output feature. The family utilizes LTCMOS switched capacitor technology for high-speed performance and low power consumption.
