LTC1408IUH-12#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1408IUH-12#TRPBF is a 12-bit, 6-channel 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. It supports unipolar (0V to 2.5V) or bipolar (-1.25V) input ranges via the BIP pin. Power consumption is 15mW in active mode, with Nap (3.3mW) and Sleep (6µW) shutdown modes. It is housed in a 32-pin 5mm × 5mm QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the #TRPBF suffix indicates a lead-free tape and reel packaging format. Confirm the component meets the industrial temperature range specifications (-40°C to 85°C) required for the 'I' grade variant. Ensure compatibility with the 3V single-supply operation and 3-wire serial interface requirements of the target system design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when six channels of simultaneous sampling are required at moderate speeds. The 12-bit resolution and 600ksps aggregate rate suit applications like motor control and power monitoring. Consider the 3V single-supply constraint and the need for differential inputs to reject common-mode noise. Evaluate if the internal 2.5V reference meets accuracy needs or if an external reference is necessary.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1408 family of SAR ADCs. The 'I' suffix denotes the industrial temperature range (-40°C to 85°C), while 'UH' specifies the 32-pin QFN package. The '#TRPBF' suffix indicates it is supplied in a tape and reel format and is lead-free compliant. It is manufactured by Analog Devices Inc., which acquired Linear Technology.
