LTC1403IMSE#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1403IMSE#TRPBF is a 12-bit, 2.8Msps serial analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single 3V supply and features differential inputs with an internal 2.5V bandgap reference. The device draws 4.7mA in active mode, dissipating 12mW of power. It includes Sleep and Nap shutdown modes for reduced power consumption. The ADC utilizes a 3-wire serial interface and is housed in a 10-lead MSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging. Confirm the IMSE suffix corresponds to the industrial temperature range of -40°C to 85°C. Ensure the 10-lead MSOP package matches the design requirements. Check RoHS compliance status as specified in the ordering information section.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-speed conversion with low power consumption. The 12-bit resolution is suitable for general-purpose data acquisition. Consider the external reference capability if higher precision than the internal 2.5V reference is needed. Ensure the driving circuit can settle within the 39ns acquisition time.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1403 family, which also includes the 14-bit LTC1403A variant. The IMSE designation specifies the industrial temperature grade and MSOP package. The #TRPBF suffix denotes lead-free tape and reel packaging for automated assembly.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1403A provides 14-bit resolution with similar speed and power characteristics. Other parts in the family include LTC1403CMSE and LTC1403HMSE for different temperature ranges.
