LTC1198-2BCS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1198-2BCS8#TRPBF is an 8-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices. It features a software-selectable 2-channel multiplexer and operates on a single supply voltage ranging from 2.7V to 6V. The device supports sampling rates up to 750kHz with a typical power dissipation of 50mW at 5V. It incorporates an auto-shutdown feature that reduces supply current to approximately 1nA when inactive. Data transfer occurs via a 3-wire serial interface compatible with SPI standards, housed in an 8-lead plastic SO package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 2-channel input multiplexer for multi-point signal acquisition
• Auto-shutdown mode with typical 1nA standby current consumption
• High-speed 8-bit SAR architecture supporting up to 750ksps sampling rate
• 3-wire serial I/O interface compatible with standard microprocessor protocols

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems
• Portable or compact instrumentation
• Battery-operated low-power systems
• Disk drive control circuits

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific B-grade temperature range specifications against the official datasheet prior to integration. Confirm that the tape and reel packaging format aligns with automated assembly requirements. Ensure the digital logic levels are compatible with the host system's voltage thresholds.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 2-channel input selection is required within a minimal footprint. The B-grade variant offers tighter total unadjusted error specifications compared to A-grade options. Consider the 750kHz maximum sampling rate limit when designing for higher frequency applications where the LTC1196 might be more suitable.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1196/LTC1198 family of high-speed, low-power ADCs. The '2' suffix denotes the inclusion of a 2-channel multiplexer, distinguishing it from the single-channel LTC1198-1 variants. The '#TRPBF' suffix indicates a lead-free finish supplied in a tape and reel configuration for surface-mount technology.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1198-2BCS8#PBF serves as the tube-packaged equivalent of this component. Designers requiring a single-channel configuration without multiplexing capabilities should consider the LTC1198-1BCS8#TRPBF instead.
