LTC1199IMS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1199IMS8#TRPBF is a 10-bit, switched-capacitor successive approximation analog-to-digital converter (ADC) housed in an 8-lead MSOP package. It features a software-selectable 2-channel multiplexer and operates on a single 4V to 6V supply. The device supports sampling rates up to 500ksps with a typical power dissipation of 25mW at full speed. An automatic shutdown mode reduces supply current linearly as the sample rate decreases. Data transfer occurs via a synchronous, half-duplex serial interface compatible with SPI and MICROWIRE protocols.

Analog To Digital Converters (ADC) Feature Summary

• 10-bit resolution with maximum sampling frequency of 500ksps
• Integrated 2-channel input multiplexer with internal VCC reference
• Synchronous 3-wire or 4-wire serial I/O interface
• Automatic power-down mode for low-power applications

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems
• Battery-operated instrumentation
• Portable compact instrumentation
• Microprocessor-based control systems

Analog To Digital Converters (ADC) Procurement Notes

Verify that the IMS8 suffix corresponds to the MSOP-8 package and the TRPBF suffix indicates tape and reel packaging. Confirm the operating temperature range matches the 'I' grade specification (-45°C to +85°C). Ensure the system voltage remains within the 4V to 6V limit for the standard LTC1199 variant.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit ADC with integrated multiplexing is required. The LTC1199 differs from the LTC1197 by including a MUX and internal reference. For lower voltage operation down to 2.7V, consider the LTC1199L variant. Ensure the clock frequency does not exceed 7.2MHz at 5V operation.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1197/LTC1199 family of 10-bit, 500ksps ADCs. It shares the same architecture as the LTC1197 but adds a 2-channel multiplexer and ties the reference internally to VCC. It serves as a 10-bit upgrade to the 8-bit LTC1196/LTC1198 series.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1199IS8#PBF is the tube-packaged equivalent. The LTC1199L variants support 2.7V operation. The LTC1197 provides differential inputs without a multiplexer.
