LTC1407AHMSE#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1407AHMSE#TRPBF is a 14-bit, 3Msps simultaneous sampling ADC with two differential inputs. It operates from a single 3V supply, drawing 5.2mA in active mode and 10μW in Sleep shutdown. The device features an internal 2.5V bandgap reference, 80dB CMRR at 100kHz, and a 3-wire serial interface. It is housed in a 10-lead MSOP package with an exposed ground pad, designed for high-speed portable applications requiring low power consumption.

Analog To Digital Converters (ADC) Feature Summary

• 14-bit resolution with 3Msps total throughput (1.5Msps per channel)
• Simultaneous sampling of two differential input channels
• Sleep shutdown mode reduces power to 10μW
• Internal 2.5V reference with external overdrive capability

Analog To Digital Converters (ADC) Applications

• Telecommunications
• Data Acquisition Systems
• Multiphase Motor Control
• I and Q Demodulation

Analog To Digital Converters (ADC) Procurement Notes

Verify the H-grade temperature range (-40°C to 125°C) matches application requirements. Confirm the MSE package type and TRPBF tape-and-reel packaging. Ensure the 14-bit resolution specification aligns with system accuracy needs compared to the 12-bit LTC1407 variant.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 14-bit precision at 1.5Msps per channel. The H-grade variant supports extended industrial temperatures up to 125°C. Consider the 3V single-supply operation and low current draw for battery-powered designs. Verify that the 2.5V input range fits the signal chain.

Analog To Digital Converters (ADC) Part Context

This part is the high-temperature (H), 14-bit (A) version of the LTC1407 family. It shares the same pinout and core architecture as the LTC1407 but offers higher resolution and wider operating temperature range. The #TRPBF suffix indicates lead-free tape and reel packaging.

Analog To Digital Converters (ADC) Replacement Considerations

LTC1407AHMSE#PBF (Tube Packaging): Identical electrical specifications; differs only in shipping container format.

Analog To Digital Converters (ADC) FAQ

What is the maximum sampling rate per channel?

Each channel samples at 1.5Msps, resulting in a combined 3Msps throughput.

Can the internal reference be overridden?

Yes, the VREF pin can be overdriven by an external reference between 2.55V and VDD.

What is the common mode rejection ratio?

The device provides 80dB CMRR at 100kHz and 60dB at 1MHz.
