LTC1092CN8#PBF

ADCs/DACs - Special Purpose Overview

The LTC1092CN8#PBF is a single-channel, 10-bit serial data acquisition system manufactured by Analog Devices Inc. It integrates a switched-capacitor successive approximation A/D converter with an on-chip sample-and-hold circuit and a unipolar input configuration. The device operates from a single +5V supply or dual ±5V supplies, consuming a maximum of 2.5mA. It features a 3-wire serial interface (CS, CLK, DOUT) for direct connection to microprocessors. Key electrical specifications include a total unadjusted error of –1LSB over temperature for the A grade, a conversion time of 20ms, and analog inputs that are common-mode to the supply rails.

ADCs/DACs - Special Purpose Feature Summary

• 10-bit SAR ADC with integrated sample-and-hold and single-channel multiplexer
• Unipolar conversion mode with analog inputs common-mode to supply rails
• 3-wire serial interface compatible with MPU ports without external hardware
• Low power consumption: 2.5mA max at VCC = 5V

ADCs/DACs - Special Purpose Applications

• Remote data acquisition systems requiring low power
• Direct sensor interfacing eliminating need for external gain stages
• Microprocessor-based measurement systems using serial I/O
• Applications requiring ratiometric conversion with internal reference

ADCs/DACs - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS3 compliance status as indicated in official documentation. Check for specific grade markings (A vs C) if tight error tolerances are required. Ensure ordering suffixes match package requirements. Review datasheet for absolute maximum ratings to prevent damage during handling.

ADCs/DACs - Special Purpose Selection Notes

Select this part for single-channel applications requiring 10-bit resolution. The LTC1092 is permanently configured for unipolar mode; use LTC1093/LTC1094 if bipolar operation is needed. Verify supply voltage compatibility (4.5V to 10V). Consider the 20ms conversion speed against application timing requirements. Ensure the microprocessor supports the required 3-wire serial protocol.

ADCs/DACs - Special Purpose Part Context

This component belongs to the LTC1091/1092/1093/1094 family of 10-bit serial data acquisition systems. The LTC1092 specifically replaces the legacy ADC0831 with enhanced accuracy and lower power. It shares the same core architecture as the LTC1091 but offers a simplified 3-wire interface due to its fixed single-channel unipolar configuration.

ADCs/DACs - Special Purpose Replacement Considerations

LTC1092CN8#PBF is a direct replacement for LTC1092CN8. Verify pinout compatibility with existing designs. Check if bipolar capability is required; if so, consider LTC1093CN8 instead.
