LTC1197IS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1197IS8#PBF is a 10-bit successive approximation register (SAR) analog-to-digital converter in an 8-lead SOIC package. It operates on a single supply voltage ranging from 4V to 9V with a maximum sampling rate of 500ksps. The device features a differential analog input and an external reference pin, supporting unipolar operation. Power dissipation is typically 25mW at full speed. It utilizes a 3-wire serial interface compatible with SPI and Microwire protocols.

Analog To Digital Converters (ADC) Feature Summary

• 10-bit resolution with 500ksps sampling rate
• Single supply operation: 4V to 9V
• Differential analog input with adjustable external reference
• Auto shutdown reduces power linearly at lower sample rates

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems
• Portable or compact instrumentation
• Low power or battery-operated instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates tube packaging rather than tape and reel. Confirm the IS8 designation corresponds to the industrial temperature range (-45°C to 85°C) and SOIC-8 package. Ensure the source document matches the Analog Devices datasheet for the LTC1197 family to validate electrical parameters.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a differential input and external reference are required. The LTC1197 differs from the LTC1199 by lacking a multiplexer and DIN pin. Verify that the system supply voltage falls within the 4V to 9V range, as the LTC1197L variant is required for 2.7V operation.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1197/LTC1197L/LTC1199/LTC1199L family of 10-bit SAR ADCs. The 'I' suffix denotes the industrial temperature grade, while 'S8' specifies the plastic SOIC-8 package. It serves as a high-speed, low-power alternative to older 8-bit devices like the LTC1196.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1197LIS8#PBF is a pin-compatible replacement for 2.7V to 4V supply applications. The LTC1199IS8#PBF offers similar performance but includes a 2-channel multiplexer and requires a DIN pin for configuration.
