LTC2622CMS8#PBF

Overview

The LTC2622CMS8#PBF is a dual 12-bit rail-to-rail voltage-output digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.5V to 5.5V and is housed in an 8-lead MSOP package. The device features built-in high-performance output buffers capable of sourcing or sinking up to 15mA, ensuring guaranteed monotonicity over the operating temperature range. It utilizes a simple SPI/Microwire compatible 3-wire serial interface with clock rates up to 50MHz. Key electrical specifications include a settling time of 7µs for ±1LSB accuracy at 12 bits, differential nonlinearity (DNL) of ±0.5 LSB, and integral nonlinearity (INL) of ±0.75 LSB.

• High drive capability with output buffers sourcing/sinking up to 15mA
• Guaranteed 12-bit monotonic operation over the full temperature range

Applications

• Mobile communications systems
• Process control and industrial automation
• Instrumentation equipment
• Automatic test equipment

Procurement Notes

Verify component authenticity through authorized distributors as counterfeit risks exist for legacy components. Confirm RoHS compliance status via official documentation. Check current lifecycle status, as this part may be subject to obsolescence notices. Ensure proper handling for ESD-sensitive devices during storage and assembly.

Selection Notes

Select the LTC2622 when dual 12-bit precision is required in a compact footprint. Compare against the LTC2602 (16-bit) or LTC2612 (14-bit) if higher resolution is needed within the same pinout. Consider power-down modes for battery-operated applications to reduce current consumption. Verify that the 2.5V to 5.5V supply range matches system requirements.

Part Context

This component belongs to the LTC2602/LTC2612/LTC2622 family of dual DACs. The CMS8 suffix indicates the commercial temperature range (0°C to 70°C) and the MSOP-8 package type. The #PBF suffix denotes lead-free packaging compliant with RoHS standards. It shares pin compatibility with other members of the series and the LTC1661.

Replacement Considerations

Pin-compatible alternatives within the same family include the LTC2602CMS8#PBF (16-bit) and LTC2612CMS8#PBF (14-bit). For lower resolution needs, the LTC1661CMS8#PBF (10-bit) offers similar form factors. Verify interface compatibility and performance parameters before substitution.
