LTC1407ACMSE-1#PBF

Analog To Digital Converters (ADC) Overview

The LTC1407ACMSE-1#PBF is a dual-channel, 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It operates at a total sampling rate of 3Msps, providing 1.5Msps throughput per channel with simultaneous differential input sampling. The device features a 3-wire serial interface, an internal 2.5V bandgap reference, and low power consumption of 14mW in active mode. It supports a sleep shutdown mode reducing power to 10μW. Designed for single 3V supply operation, it offers a ±1.25V differential input range and comes in a compact 10-lead MSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'AC' indicates the commercial temperature grade (0°C to 70°C) and lead-free finish as documented in the manufacturer's ordering information. Confirm the package type is the 10-lead plastic MSOP. Ensure compatibility with single 3V supply requirements and serial interface timing constraints before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous dual-channel conversion is required at high speeds. The 14-bit resolution distinguishes it from the 12-bit LTC1407-1 variant. Consider the 0°C to 70°C operating range; for industrial temperatures (-40°C to 85°C), select the AI version. Verify that the 3-wire serial interface matches the host controller capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1407-1/LTC1407A-1 family of simultaneous sampling ADCs. The 'A' designation denotes the 14-bit resolution variant, while 'C' specifies the commercial temperature range. It shares pinout and functionality with the LTC1407-1 but offers higher precision. The exposed pad must be soldered to the PCB ground plane for proper thermal and electrical performance.
