LTC1407ACMSE#PBF

Analog To Digital Converters (ADC) Overview

The LTC1407ACMSE#PBF is a 14-bit, 3Msps simultaneous sampling analog-to-digital converter (ADC) from Analog Devices. It features two independent differential inputs, each sampled at 1.5Msps on the rising edge of the CONV signal. The device operates from a single 3V supply, drawing 4.7mA in active mode and consuming only 10μW in Sleep shutdown mode. It includes an internal 2.5V bandgap reference and outputs data via a 3-wire serial interface over 32 clocks. The component 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 at 1.5Msps per channel for a total throughput of 3Msps.
• Low Power Consumption: Active mode current is 4.7mA at 3V; Sleep mode reduces power to 10μW.
• Differential Inputs: Supports 0V to 2.5V unipolar differential input range with 80dB common mode rejection at 100kHz.
• Serial Interface: 3-wire compatible output with three-state SDO pin.

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 specific ordering suffix ACMSE#PBF against manufacturer documentation to confirm the commercial temperature range (0°C to 70°C) and lead-free finish. Ensure compatibility with the 10-lead MSOP footprint and exposed pad soldering requirements during assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring simultaneous sampling of two differential signals at high speed with low power constraints. The LTC1407A variant provides 14-bit resolution compared to the 12-bit LTC1407. Ensure the driving circuit can settle within the 39ns acquisition time and that the source impedance is managed to maintain bandwidth.
