LTC1197CS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1197CS8#PBF is a 10-bit successive approximation register (SAR) analog-to-digital converter in an 8-lead SOIC package. It operates on a single 4V to 9V supply with a typical power dissipation of 25mW at full speed. The device features a differential analog input and an external reference pin, supporting sampling rates up to 500ksps. It utilizes a 3-wire serial interface compatible with SPI and MICROWIRE protocols. Key electrical characteristics include a maximum clock frequency of 7.2MHz, a gain error of 4 LSB, and a signal-to-noise plus distortion ratio of 60dB.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix CS8 corresponds to the commercial temperature range (0°C to 70°C) and SOIC-8 package. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the ordering part number matches the required voltage range specifications for the LTC1197 variant.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-speed conversion with low power consumption. The LTC1197 is suitable for differential signal inputs and external reference configurations. For single-supply 2.7V operation, consider the LTC1197L variant. Ensure the system clock does not exceed 7.2MHz when operating at 5V.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1197 family of 10-bit ADCs. It serves as a higher-resolution upgrade to the 8-bit LTC1196/LTC1198 series. The CS8 suffix indicates the commercial temperature grade and plastic SOIC packaging, distinguishing it from the industrial grade IS8 or MSOP variants.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1197LCS8#PBF is a pin-compatible alternative for 2.7V to 4V supply applications. The LTC1199CS8#PBF offers a 2-channel multiplexer but lacks the differential input capability of the LTC1197.
