LTC2605IGN#TRPBF

Digital To Analog Converters Overview

The LTC2605IGN#TRPBF is an octal 16-bit rail-to-rail voltage-output DAC in a 16-lead narrow SSOP package. It features built-in high-performance output buffers and operates on a single supply of 2.7V to 5.5V. The device uses a 2-wire I²C compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. It incorporates a power-on reset circuit that holds outputs at zero-scale until a valid write and update occur. Key specifications include ±1 LSB DNL, ±16 LSB INL, and individual channel power-down capability.

Digital To Analog Converters Feature Summary

• Octal 16-bit resolution with guaranteed monotonicity over temperature
• Rail-to-rail voltage outputs with ±15mA minimum drive current
• I²C compatible serial interface with 27 selectable addresses
• Power-on reset to zero-scale with <10mV glitch amplitude

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging for the industrial grade (-40°C to 85°C) variant. Confirm the absence of the '-1' suffix ensures power-on reset behavior defaults to zero-scale rather than mid-scale. Ensure the order matches the required lead finish and temperature range specifications.

Digital To Analog Converters Selection Notes

Select this component when eight independent 16-bit channels are required in a compact footprint. Compare against LTC2615 or LTC2625 if lower resolution allows for cost reduction. Verify that the I²C bus capacitance does not exceed limits for the desired clock speed without active pull-ups. Check load regulation requirements against the specified LSB/mA values.

Digital To Analog Converters Part Context

This part belongs to the LTC2605/LTC2615/LTC2625 family of octal DACs. The IGN suffix denotes the industrial temperature range (-40°C to 85°C). The TRPBF suffix indicates tape and reel packaging with lead-free finish. It shares pinout compatibility with the 14-bit and 12-bit variants in the same series.

Digital To Analog Converters Replacement Considerations

LTC2605CGN#TRPBF offers the same electrical performance but is rated for commercial temperature range (0°C to 70°C). LTC2605IGN-1#TRPBF provides identical functionality but resets to mid-scale upon power-up instead of zero-scale.
