LTC1407AIMSE-1#PBF

Analog To Digital Converters (ADC) Overview

The LTC1407AIMSE-1#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 achieves a total sampling rate of 3Msps with two simultaneous differential inputs, providing 1.5Msps throughput per channel. The device features a 2.5V internal bandgap reference, a 3-wire serial interface, and low power consumption of 14mW in active mode. It includes sleep and nap shutdown modes for reduced power usage. Packaged in a 10-lead MSOP with an exposed ground pad, it supports bipolar differential input ranges of ±1.25V.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel SAR ADC with 14-bit resolution and 3Msps total simultaneous sampling rate
• Low power operation: 14mW active dissipation; 10μW in sleep mode
• Integrated 2.5V internal bandgap reference with external overdrive capability
• 3-wire serial interface with three-state output and 80dB common mode rejection

Analog To Digital Converters (ADC) Applications

• Telecommunications systems
• Data acquisition systems
• Multiphase motor control
• I & Q demodulation
• Industrial radio applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free finish and RoHS compliance as per manufacturer standards. Confirm the MSE package variant matches the required PCB footprint. Ensure the industrial temperature range (-40°C to 85°C) aligns with system environmental requirements. Check current availability status through authorized distributors as supply levels may fluctuate.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous dual-channel conversion at high speed is required within a compact form factor. The 14-bit resolution offers higher precision than the 12-bit LTC1407-1 variant. Consider the internal 2.5V reference for cost-sensitive designs or use an external reference >2.55V for improved performance. Ensure the driving circuit can settle within the 39ns acquisition time for full throughput rates.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1407-1/LTC1407A-1 family of serial SAR ADCs. The 'A' designation denotes the 14-bit resolution version, while the base model offers 12 bits. Both share identical pinouts and functionality, differing primarily in resolution and associated linearity specifications. The IMSE-1 suffix specifies the industrial temperature grade and MSOP package.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1407IMSE-1#PBF serves as the 12-bit resolution equivalent within the same package and pinout. Designers requiring lower resolution but identical interface and power characteristics may substitute this part. Verify that the 12-bit accuracy meets the application's noise and linearity requirements before swapping.
