LTC1408CUH-12#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1408CUH-12#TRPBF is a 6-channel, 12-bit simultaneous sampling analog-to-digital converter (ADC) from Analog Devices Inc. It operates on a single 3V supply with a total sampling rate of 600ksps, providing 100ksps throughput per channel. The device features six differential inputs, an internal 2.5V reference, and a 3-wire SPI-compatible serial interface. Key specifications include 72dB SINAD at 100kHz, 83dB common mode rejection, and low power consumption of 15mW in active mode. It supports unipolar (0V to 2.5V) or bipolar (-1.25V) input ranges and includes Nap and Sleep shutdown modes for reduced power dissipation.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Applications

• Multiphase power measurement
• Multiphase motor control
• Data acquisition systems
• Uninterruptable power supplies

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF confirms the component is supplied in tape and reel packaging and is lead-free compliant. Confirm the 'C' grade designation indicates an operating temperature range of 0°C to 70°C. Ensure the QFN package marking matches the specific lot requirements for your assembly process.

Analog To Digital Converters (ADC) Selection Notes

Select this part when six simultaneous differential channels are required within a compact 32-pin QFN footprint. It is suitable for applications needing low power consumption with a single 3V supply. Consider the 39ns acquisition time and source impedance requirements if driving high-impedance signals directly without buffering.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1408 family of SAR ADCs. The 'UH' suffix denotes the 32-pin 5mm x 5mm QFN package. The '#TRPBF' suffix indicates Tape and Reel packaging with Lead-Free finish. It is distinct from evaluation boards like the DC887A, which utilizes the bare LTC1408 IC.
