LTC1296CIN#PBF

ADCs/DACs - Special Purpose Overview

The LTC1296CIN#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 input channels configurable for single-ended or differential inputs. It operates on a single +5V supply or ±5V supplies with a maximum throughput rate of 46.5 kS/s. Key features include software-programmable unipolar/bipolar conversion modes, power shutdown capability, and a System Shutdown Output (SSO) pin. The serial interface allows direct connection to microprocessor ports.

ADCs/DACs - Special Purpose Feature Summary

• 12-bit resolution with 8-channel analog multiplexer
• Software programmable for unipolar or bipolar operation
• System Shutdown Output (SSO) pin for external power control
• Direct 4-wire serial interface compatible with most MPU ports

ADCs/DACs - Special Purpose Applications

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

ADCs/DACs - Special Purpose Procurement Notes

Verify the package type matches the required PCB footprint. The 'C' suffix indicates commercial temperature range (0°C to 70°C). Confirm RoHS compliance status as specified in the ordering information section of the datasheet. Ensure the specific lot date code meets project requirements if traceability is critical.

ADCs/DACs - Special Purpose Selection Notes

Select this component when 12-bit accuracy and low channel count are required. The LTC1296 includes the SSO pin not present in the LTC1293 or LTC1294 variants. Choose the 'I' suffix for industrial temperature range (-40°C to 85°C) if operating conditions exceed commercial limits. Verify that the serial interface timing aligns with the target microprocessor's clock specifications.

ADCs/DACs - Special Purpose Part Context

This part belongs to the LTC1293/4/6 family of single-chip data acquisition systems. The LTC1296 is distinguished from the LTC1293 and LTC1294 by the inclusion of the System Shutdown Output (SSO) pin. All variants share identical ADC performance and multiplexer configurations but differ in pinout availability for shutdown signaling.

ADCs/DACs - Special Purpose Replacement Considerations

The LTC1296BIN and LTC1296DIN are pin-compatible alternatives offering industrial and extended temperature ranges respectively. The LTC1294CCN is functionally similar but lacks the SSO pin. Verify pin 19 connectivity; the LTC1296 uses it for SSO while other family members may use it for DVCC.
