LTC1198-1ACS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1198-1ACS8#TRPBF is an 8-bit successive approximation register (SAR) analog-to-digital converter (ADC) in an 8-lead plastic SO package. It operates on a single 2.7V to 6V supply with power dissipation of 10mW at 3V and 50mW at 5V. The device features a software-selectable 2-channel multiplexer and auto-shutdown capability, drawing only 1nA typical current when disabled. It supports sampling rates up to 750kHz with a 3-wire serial interface.

Analog To Digital Converters (ADC) Feature Summary

• Auto-Shutdown: Typical 1nA supply current when CS is HIGH
• High Speed: 750kHz maximum sampling rate
• Accuracy: ±1/2 LSB total unadjusted error over temperature for A-grade devices
• Interface: 3-wire serial I/O compatible with standard digital logic

Analog To Digital Converters (ADC) Applications

• Single 5V Supply, 1Msps, 8-Bit Sampling ADC
• High Speed Data Acquisition
• Disk Drives
• Portable or Compact Instrumentation
• Low Power or Battery-Operated Systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging. Confirm the '1' designation corresponds to the A-grade accuracy specification. Ensure the SO-8 package dimensions match the target PCB footprint requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring high sample rates with low power consumption. The 2-channel MUX allows differential or single-ended input selection via DIN. Verify that the external clock frequency supports the desired throughput without exceeding the 14.4MHz limit at 5V operation.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1196/LTC1198 family of 8-bit SAR ADCs. The LTC1198 variant specifically includes a 2-channel multiplexer and auto-shutdown feature, distinguishing it from the single-input LTC1196. Both share similar electrical characteristics and pinouts.

Analog To Digital Converters (ADC) Replacement Considerations

LTC1198-1BCS8#TRPBF offers B-grade specifications. LTC1196-1ACS8#TRPBF provides a single differential input without the multiplexer or auto-shutdown functionality.
