LTC2627IDE-1#TRPBF

Overview

The LTC2627IDE-1#TRPBF is a dual 12-bit rail-to-rail voltage output digital-to-analog converter (DAC) from Analog Devices. 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 (100kHz) and fast (400kHz) modes. Key specifications include a settling time of 7µs, ±0.5 LSB differential nonlinearity, and ±1.5 LSB integral nonlinearity. It incorporates a power-on reset circuit that defaults outputs to mid-scale and offers low power consumption with 260µA per DAC at 3V.

Feature Summary

• Dual 12-bit resolution with guaranteed monotonicity over temperature
• I²C interface with 27 selectable addresses and global address support
• Power-on reset to mid-scale for the -1 suffix variant
• Ultralow crosstalk of 30µV and high rail-to-rail output drive capability

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the 'I' grade designation corresponds to the –40°C to +85°C operating temperature range required for the application environment. Ensure the -1 suffix is selected if mid-scale power-on reset behavior is necessary for system initialization.

Selection Notes

Select the LTC2627IDE-1#TRPBF when dual-channel 12-bit precision is required in a compact form factor. The -1 suffix ensures outputs default to mid-scale upon power-up, which may be critical for specific safety or initialization protocols. Compare against the standard LTC2627IDE#TRPBF if zero-scale reset is preferred instead. Consider the 12-bit resolution limits for applications requiring higher linearity than ±1.5 LSB INL.

Part Context

This part belongs to the LTC2607/LTC2617/LTC2627 family of dual rail-to-rail DACs. While pin-compatible, the LTC2627 provides 12-bit resolution compared to the 16-bit LTC2607 and 14-bit LTC2617. All variants share the same 12-lead DFN package and I²C interface architecture, allowing for design flexibility across different resolution requirements within the same board layout.
