LTC1197IMS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1197IMS8#PBF 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 both single-ended and differential input configurations. Power dissipation is typically 25mW at full speed with 5V operation. It utilizes a 3-wire serial interface compatible with SPI and Microwire protocols.

Analog To Digital Converters (ADC) Feature Summary

• 10-bit resolution with up to 500ksps sampling rate
• Single supply operation from 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 when sourcing components. Confirm that the IMS8 designation corresponds to the industrial temperature range (-45°C to 85°C). Ensure the supply voltage requirements align with the 4V to 9V operating specification for this variant rather than the 2.7V L-series parts.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1197 over the LTC1199 if a differential input and external reference are required, as the LTC1199 includes an internal multiplexer and fixed reference. Consider the LTC1197L if the system operates strictly on a 2.7V supply, noting the reduced maximum clock frequency of 3.5MHz compared to the 7.2MHz available at higher voltages.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1197 family of 10-bit ADCs manufactured by Analog Devices Inc. The 'I' suffix denotes the industrial temperature grade, while 'MS8' specifies the 8-lead Mini Small Outline 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 LTC1197LIMS8#PBF is a pin-compatible alternative designed for 2.7V to 4V supplies with a lower maximum sampling rate of 250ksps.
