LTC1408IUH-12#PBF

Analog To Digital Converters (ADC) Overview

The LTC1408IUH-12#PBF is a 12-bit, 6-channel simultaneous sampling analog-to-digital converter (ADC) from Analog Devices Inc. It operates on a single 3V supply and delivers a total throughput of 600ksps, with each channel converting at 100ksps. The device features six differential inputs, an internal 2.5V reference, and a 3-wire SPI-compatible serial interface. Key electrical parameters include a typical SINAD of 72dB at 100kHz input, 90dB SFDR, and 83dB CMRR. Power consumption is 15mW in active mode, reducible to 6µW via the SLEEP shutdown feature. It is housed in a compact 32-pin 5mm × 5mm QFN package.

Analog To Digital Converters (ADC) Feature Summary

• Six simultaneously sampled differential inputs with 100ksps per channel throughput
• Low power operation: 15mW active, 3.3mW NAP mode, and 6µW SLEEP mode
• Internal 2.5V bandgap reference with external reference capability
• Configurable bipolar (-1.25V) or unipolar (0V to 2.5V) 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 that the ordering suffix #PBF confirms lead-free compliance and tube packaging. Confirm the 'I' grade designation matches the required -40°C to +85°C industrial operating temperature range. Ensure the QFN-32 package dimensions align with the PCB footprint design.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring simultaneous multi-channel sampling without inter-channel skew. The 12-bit resolution and 600ksps aggregate rate suit moderate-speed data acquisition. Consider the 3V single-supply constraint and verify that the driving source impedance allows for the specified 39ns acquisition time.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1408 family of high-performance SAR ADCs. The 'I' suffix denotes the industrial temperature variant, while 'UH' specifies the 32-pin plastic QFN package. The '#PBF' indicates a lead-free finish compliant with RoHS standards. It is manufactured by Analog Devices Inc., following their acquisition of Linear Technology.
