LTC1407AIMSE#PBF

Analog To Digital Converters (ADC) Overview

The LTC1407AIMSE#PBF is a dual-channel, 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It operates on a single 3V supply and delivers a combined sampling rate of 3Msps, with each channel providing 1.5Msps throughput. The device features simultaneous sampling of two differential inputs via a serial interface. Key electrical specifications include a typical power dissipation of 14mW in active mode, an internal 2.5V bandgap reference, and a full-power bandwidth of 50MHz. It is housed in a compact 10-lead MSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel architecture with simultaneous sampling at 3Msps total (1.5Msps per channel).
• Low power consumption: 14mW typical active power; Sleep mode reduces current to 10μW.
• Integrated 2.5V internal bandgap reference with external overdrive capability.
• 80dB common mode rejection ratio (CMRR) at 100kHz for noise immunity.

Analog To Digital Converters (ADC) Applications

• Telecommunications systems
• Data acquisition systems
• Multiphase motor control
• I and Q demodulation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and RoHS compliance. Confirm the temperature grade 'I' corresponds to the -40°C to +85°C operating range required for the application. Ensure the 10-lead MSOP package dimensions match the PCB footprint constraints.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous conversion of two channels is required at high speeds. The 14-bit resolution provides higher precision than the 12-bit LTC1407 variant. Consider the 50MHz full-power bandwidth and 1.5Msps per channel throughput for signal processing requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1407 family of high-speed, low-power ADCs. The 'A' designation specifies 14-bit resolution, distinguishing it from the 12-bit standard version. The 'IMSE' suffix denotes the industrial temperature range (-40°C to +85°C) and the 10-lead MSOP plastic package.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1407IMSE#PBF serves as a lower-resolution alternative if 12-bit accuracy is sufficient. Verify that the pinout and package dimensions remain compatible during substitution.
