LTC1098IN8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1098IN8#PBF is an 8-bit micropower switched-capacitor successive approximation A/D converter in an 8-lead Plastic SOIC package. It features a software-selectable 2-channel multiplexer and draws 80μA maximum supply current during conversion, dropping to 1nA typical in shutdown. The device operates on a single 5V supply (3.0V to 6.0V) with a 3-wire serial interface for data transfer. Key electrical characteristics include a 16μs conversion time, 33kHz maximum sample rate, and ±0.5LSB total unadjusted error over the industrial temperature range of –40°C to 85°C.

Analog To Digital Converters (ADC) Feature Summary

• Micropower consumption: 80μA active, 1nA shutdown
• Integrated 2-channel analog multiplexer
• 3-wire synchronous serial interface compatible with microprocessors
• Built-in sample-and-hold circuit

Analog To Digital Converters (ADC) Applications

• Battery-operated systems
• Remote data acquisition
• Battery monitoring and gas gauges
• Temperature measurement
• Isolated data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and tape/reel availability if required. Confirm the IN8 designation corresponds to the 8-lead Plastic DIP package variant rather than the S8 SOIC package when reviewing inventory or datasheet cross-references. Ensure the temperature grade 'I' matches the –40°C to 85°C requirement for the specific application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power and multiplexed inputs. The LTC1098 differs from the LTC1096 by including a 2-channel MUX instead of a differential input. Ensure the system clock frequency does not exceed 500kHz at 5V operation. Verify that the analog input range fits within VCC + 0.05V limits and that the reference voltage requirements align with the 5V supply configuration.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1096/LTC1098 family of 8-bit micropower ADCs. The 'IN8' suffix specifies the Industrial temperature grade (–40°C to 85°C) and the N8 8-lead Plastic DIP package. The '#PBF' suffix denotes a lead-free finish. It shares core architecture with the LTC1096 but adds multiplexing capability via the DIN pin.
