LTC1098CN8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1098CN8#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 maximum sampling rate of 33kHz at 500kHz clock frequency. It includes an on-chip sample-and-hold and provides serial data output via a 3-wire interface compatible with most microprocessor ports.

Analog To Digital Converters (ADC) Feature Summary

• 8-bit resolution with ±0.5LSB total unadjusted error over temperature
• Micropower consumption: 80μA active, 1nA shutdown
• Software-selectable 2-channel input multiplexer
• Direct 3-wire serial interface for data transfer

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 part marking '1098' on the component body matches the order information for the CN8 suffix. Confirm the lead finish is Pb-free as indicated by the #PBF suffix. Ensure the operating temperature range of 0°C to 70°C meets system requirements. Cross-reference the datasheet revision 10968fc for accurate electrical specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC1096 variant when a 2-channel multiplexer is required instead of a differential input. The CN8 suffix denotes the 8-lead Plastic DIP package; use CS8 for the SOIC package. Verify that the 5V operation range (3V to 6V) suits the power supply, noting that the L-series variants support lower voltages down to 2.65V if needed.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1096/LTC1098 family of micropower 8-bit ADCs. The LTC1098 variant specifically adds a 2-channel MUX compared to the single-differential-input LTC1096. The CN8 designation identifies the commercial grade (0°C to 70°C) in an 8-lead Plastic DIP package. The #PBF suffix indicates a lead-free finish compliant with RoHS standards.
