LTC1197IMS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1197IMS8#TRPBF is a 10-bit successive approximation register (SAR) analog-to-digital converter in an 8-lead MSOP 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 (5V supply). It utilizes a 3-wire serial interface compatible with SPI and Microwire protocols. The 'I' suffix indicates an industrial operating temperature range of –45°C to 85°C.

Analog To Digital Converters (ADC) Feature Summary

• 10-bit resolution with 500ksps sampling rate
• Single supply operation: 4V to 9V
• Differential analog input with external VREF pin
• 3-wire serial I/O compatible with SPI/Microwire
• 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 component marking LTJA corresponds to the LTC1197IMS8 variant. Confirm the presence of the #TRPBF suffix for tape and reel packaging and Pb-free compliance. Ensure the digital logic levels match the system's VCC range, as thresholds vary with supply voltage.

Analog To Digital Converters (ADC) Selection Notes

Select this part over the LTC1197L series when a higher supply voltage (up to 9V) is required. The IMS8 package provides an 8-lead MSOP form factor suitable for space-constrained designs. Note that unlike the LTC1199, this specific model lacks an internal multiplexer and requires an external reference voltage.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1197 family of 10-bit SAR ADCs. It is distinct from the LTC1197L (2.7V operation), LTC1199 (multiplexed inputs), and LTC1196/1198 (8-bit resolution). The IMS8 designation specifies the industrial temperature grade and MSOP package type within the broader product line.
