LTC1283ACN#PBF

ADCs/DACs - Special Purpose Overview

The LTC1283ACN#PBF is a 3V single-chip data acquisition system featuring a 10-bit successive approximation analog-to-digital converter. It integrates an 8-channel analog multiplexer and a sample-and-hold circuit, supporting both unipolar and bipolar conversion modes. The device operates on a single 3.3V supply or ±3.3V dual supplies, with a maximum throughput rate of 15kHz. Key electrical specifications include a maximum offset error of ±0.5LSB, linearity error of ±0.5LSB, and gain error of ±1LSB for the AC grade. It utilizes a synchronous full-duplex serial interface compatible with standard microprocessor ports.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 10-bit SAR ADC with 8-channel MUX and on-chip sample-and-hold
• Software-programmable for unipolar/bipolar operation and MSB/LSB-first data output
• Direct 4-wire serial interface to MPU serial or parallel ports
• Low power consumption: 350μA max supply current at 3V

ADCs/DACs - Special Purpose Applications

• Portable battery-powered instrumentation
• Industrial process control systems
• Data acquisition modules requiring low voltage operation

ADCs/DACs - Special Purpose Procurement Notes

Verify the component marking against the official Analog Devices lead-free part marking guide to confirm authenticity. Ensure the package matches the 20-lead plastic DIP specification. Confirm RoHS compliance status through the manufacturer's current documentation as distribution channels may vary.

ADCs/DACs - Special Purpose Selection Notes

Select the LTC1283ACN#PBF for applications requiring 10-bit resolution with a maximum gain error of ±1LSB. The LTC1283CN variant offers a ±2LSB gain error limit suitable for less critical applications. Ensure the design supports the required 3V to 3.6V positive supply and optional negative supply range.

ADCs/DACs - Special Purpose Part Context

This component belongs to the LTC1283 family of 3V data acquisition systems manufactured by Analog Devices Inc. The 'AC' suffix denotes the accuracy grade with tighter gain error specifications compared to the standard 'C' grade. The '#PBF' suffix indicates a lead-free finish compliant with RoHS directives.
