LTC1199LIMS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1199LIMS8#PBF is a 10-bit, 250ksps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It operates on a single 2.7V to 4V supply and features an internal multiplexer for two input channels. The device utilizes a serial interface compatible with SPI and Microwire protocols. Key electrical specifications include a typical power dissipation of 2.2mW at full speed, a maximum sampling frequency of 250kHz, and a signal-to-noise plus distortion ratio of 58dB. It is housed in an 8-lead MSOP package.

Analog To Digital Converters (ADC) Feature Summary

• 10-bit resolution with a maximum sampling rate of 250ksps
• Single 2.7V to 4V supply operation with 2.2mW typical power dissipation
• Internal 2-channel multiplexer with software-selectable configuration
• SPI and Microwire compatible 3-wire or 4-wire serial interface

Analog To Digital Converters (ADC) Applications

• Portable or compact instrumentation systems
• Low power or battery-operated measurement devices
• High-speed data acquisition applications requiring low voltage operation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IMS8' corresponds to the industrial temperature range (-45°C to 85°C) and MSOP-8 package as defined in the official datasheet. Confirm that the '#PBF' designation indicates lead-free compliance and RoHS adherence before procurement. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit ADC is required with a 2.7V supply constraint and dual-channel input capability. The LTC1199L series is suitable for applications needing automatic shutdown to reduce power consumption at lower sample rates. Ensure the system clock frequency does not exceed 3.5MHz for stable operation at 2.7V.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1197/LTC1197L/LTC1199/LTC1199L family of 10-bit, 500ksps ADCs. The 'L' variant specifically denotes support for 2.7V operation, distinguishing it from the standard 5V versions. The 'I' suffix indicates the industrial temperature grade, while 'MS8' identifies the 8-lead MSOP plastic package format.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1197LIMS8#PBF serves as a direct functional replacement if differential inputs are acceptable, though it lacks the internal multiplexer. For pin-compatible upgrades within the same voltage range, verify the specific temperature and package suffixes match the design requirements.
