LTC1198-1BCS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1198-1BCS8#PBF is an 8-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices. It operates with a single 5V digital supply and an analog supply ranging from 2.7V to 6V, housed in an 8-pin SOIC package. The device features two channels, supporting differential or single-ended inputs, and utilizes a 3-wire SPI interface. Key electrical parameters include a maximum sampling rate of 900 kSPS, 1 LSB DNL, 0.5 LSB INL, and 50 mW power dissipation.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel SAR ADC architecture with 8-bit resolution
• High-speed conversion capability up to 900 kSPS
• Integrated auto-shutdown mode for low-power applications
• Flexible input configuration supporting differential and single-ended signals

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring low power consumption
• Battery-powered data acquisition modules
• Industrial process control signal conditioning
• Medical equipment with strict power constraints

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging. Confirm the -1B grade corresponds to the specified temperature range and accuracy metrics found in the official datasheet. Ensure the source document explicitly lists this part number as active or available, as distribution status varies by region.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel 8-bit performance at high speeds is required within a compact SO-8 footprint. Compare against the LTC1196 series if lower speed or single-channel operation suffices. Verify that the external reference requirement aligns with system design constraints, as this device does not integrate an internal voltage reference.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1198 family of 8-bit, 1MSPS ADCs with auto-shutdown options. It shares architectural similarities with the LTC1196 but offers dual-channel capability. The -1B designation typically denotes a specific industrial temperature range and performance grade within the Linear Technology portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1198-1ACS8#PBF serves as a direct functional substitute within the same family, differing primarily in temperature grade or minor electrical specifications. Cross-reference the exact pinout and software compatibility before substitution.
