Analog To Digital Converters (ADC) datasheet and documents for LTC1408IUH#PBF

LTC1408IUH#PBF

Analog To Digital Converters (ADC) Overview

The LTC1408IUH#PBF is a 14-bit, 600ksps analog-to-digital converter featuring six simultaneously sampled differential inputs. It operates from a single 3V supply, drawing 5mA in active mode and consuming only 6µW in Sleep shutdown mode. The device provides 100ksps throughput per channel with a 90dB common-mode rejection ratio. It accepts 0V to 2.5V unipolar or ±1.25V bipolar differential input ranges via a 3-wire serial interface. Packaged in a compact 32-pin 5mm × 5mm QFN, it integrates a 2.5V internal bandgap reference suitable for portable data acquisition systems.

Analog To Digital Converters (ADC) Feature Summary

Six simultaneous sampling differential inputs with 100ksps per-channel throughput
Low power consumption: 15mW active, 3.3mW Nap mode, 6µW Sleep mode
90dB common-mode rejection ratio for noise elimination
Configurable unipolar (0V–2.5V) or bipolar (±1.25V) input ranges

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 #PBF suffix confirms lead-free compliance and RoHS adherence. Confirm the IUH suffix indicates the industrial temperature range (-40°C to +85°C). Ensure the QFN-32 package matches the PCB footprint requirements. Check for specific tape and reel availability if automated assembly is required.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous multi-channel sampling is critical. The 14-bit resolution and 76dB SINAD support high-precision applications. Consider the 39ns acquisition time and source impedance limitations. Verify that the 3V single-supply operation aligns with system power constraints.

Analog To Digital Converters (ADC) Part Context

The LTC1408 is part of Analog Devices' portfolio of high-performance data converters. Originally developed by Linear Technology, it serves as a specialized solution for multi-channel signal conditioning. The IUH variant specifically targets industrial environments requiring extended temperature stability within a minimal footprint.
