LTC1407ACMSE#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1407ACMSE#TRPBF is a 14-bit, 3Msps simultaneous sampling analog-to-digital converter (ADC) from Analog Devices Inc. It features two independent differential inputs, each operating at a 1.5Msps throughput rate. The device operates on a single 3V supply and includes an internal 2.5V bandgap reference. Key electrical specifications include a typical power dissipation of 14mW in active mode and a sleep shutdown mode consuming only 10μW. It utilizes a 3-wire serial interface for data output and is housed in a 10-lead MSOP package with an exposed ground pad.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous Sampling: Two differential channels sampled concurrently on the rising edge of the CONV signal.
• Low Power Consumption: Draws 4.7mA in active mode; reduces to 10μW in Sleep mode and 3mW in Nap mode.
• Differential Input Range: Accepts 0V to 2.5V unipolar differential inputs with a common mode range extending from ground to VDD.
• High CMRR: Provides 80dB common mode rejection ratio at 100kHz to eliminate ground loops and noise.

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity by checking the part marking 'LTAFE' against the datasheet order information table. Confirm the package type is a 10-Lead Plastic MSOP with an exposed pad. Ensure the temperature grade corresponds to the commercial range (0°C to 70°C) as indicated by the suffix 'A'. Cross-reference the manufacturer number with official Analog Devices documentation to avoid counterfeit parts.

Analog To Digital Converters (ADC) Selection Notes

Select this model when dual-channel simultaneous sampling is required at high speeds up to 3Msps total. The LTC1407A variant provides 14-bit resolution, whereas the standard LTC1407 offers 12-bit resolution. Consider the internal 2.5V reference limitations; if higher precision or different voltage spans are needed, an external reference overdriving the VREF pin may be necessary. Ensure the driving circuit can settle within the 39ns acquisition time for full throughput rates.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1407/LTC1407A family of high-speed, low-power ADCs. The 'AC' suffix denotes the commercial temperature grade (0°C to 70°C), while the 'CMSE' indicates the 10-lead MSOP plastic package. The '#TRPBF' suffix specifies tape and reel packaging with lead-free finish. This series is designed for portable applications requiring high speed and minimal power consumption.
