LTC1408IUH#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1408IUH#TRPBF is a 6-channel, 14-bit, 600ksps simultaneous sampling analog-to-digital converter (ADC) from Analog Devices Inc. It features six differential inputs sampled concurrently on the rising edge of the CONV signal, providing 100ksps throughput per channel. The device operates on a single 3V supply, drawing 5mA in active mode and consuming only 6µW in Sleep shutdown mode. It includes a 2.5V internal bandgap reference, supports unipolar (0V to 2.5V) or bipolar (±1.25V) input ranges via the BIP pin, and utilizes a 3-wire serial interface for data output. The component is housed in a compact 32-pin (5mm × 5mm) QFN package.

Analog To Digital Converters (ADC) Feature Summary

• Six simultaneously sampled differential inputs with 14-bit resolution and 600ksps aggregate sampling rate
• Low power consumption: 15mW active, 3.3mW Nap mode, and 6µW Sleep mode
• 90dB common mode rejection ratio (CMRR) for noise elimination
• Configurable channel selection via SEL2, SEL1, and SEL0 pins

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 that the #TRPBF suffix confirms the component is supplied in tape and reel packaging and is lead-free compliant. Confirm the 'I' grade designation indicates an operating temperature range of –40°C to +85°C. Ensure the source documentation matches the specific lot and revision for manufacturing compatibility.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous multi-channel sampling is required at 14-bit resolution. It is suitable for applications needing low power dissipation in portable devices. Ensure the input signal range matches the selected BIP pin configuration (unipolar or bipolar). Verify that the driving circuit can settle within the 39ns acquisition time if high source impedance is present.

Analog To Digital Converters (ADC) Part Context

The LTC1408 is part of the Linear Technology (now Analog Devices) portfolio of high-performance data converters. It was originally designed by Linear Technology Corporation before its acquisition by Analog Devices. The device is commonly used in industrial and communication systems requiring efficient multi-channel signal digitization.
