LTC2605CGN#TRPBF

Digital To Analog Converters Overview

The LTC2605CGN#TRPBF is an octal 16-bit rail-to-rail voltage-output digital-to-analog converter (DAC) in a 16-lead narrow SSOP package. It operates on a single supply voltage ranging from 2.7V to 5.5V and features built-in high-performance output buffers. The device utilizes a 2-wire I²C compatible serial interface supporting standard mode (100kHz) and fast mode (400kHz). Key electrical specifications include a differential nonlinearity (DNL) of ±0.5 LSB, integral nonlinearity (INL) of ±1 LSB, and a settling time of 7µs for 16-bit accuracy. The unit incorporates a power-on reset circuit that initializes outputs to zero-scale.

Digital To Analog Converters Feature Summary

• Octal configuration with eight independent 16-bit DAC channels in a compact 16-lead SSOP package
• Rail-to-rail voltage output with high drive capability (±15mA minimum sourcing/sinking)
• Ultralow crosstalk between channels (<10µV) and double-buffered digital inputs
• I²C interface with 27 selectable addresses via CA0-CA2 pins and global address support

Digital To Analog Converters Applications

• Mobile communications systems requiring multi-channel signal generation
• Process control and industrial automation instrumentation
• Automatic test equipment needing precise analog voltage references

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix '#TRPBF' confirms tape and reel packaging versus tube packaging ('#PBF'). Confirm the 'GN' suffix indicates the commercial temperature range (0°C to 70°C) rather than the industrial range ('IGN'). Ensure the base part number matches the 16-bit resolution variant, distinct from the 14-bit LTC2615 or 12-bit LTC2625.

Digital To Analog Converters Selection Notes

Select this component when board density is critical due to its pin-compatible octal architecture. Choose the '-1' suffix variant if mid-scale power-on reset is required instead of zero-scale. Ensure the application load current does not exceed 15mA at 5V or 7.5mA at 3V to maintain specified load regulation. Verify I²C bus capacitance limits if operating in fast mode.

Digital To Analog Converters Part Context

This part belongs to the LTC2605/LTC2615/LTC2625 family of octal DACs. The LTC2605 specifically provides 16-bit resolution, while sibling parts offer 14-bit (LTC2615) and 12-bit (LTC2625) resolutions. All variants share the same 16-lead SSOP footprint and functional block diagram, differing primarily in data word length and linearity specifications.
