LTC2617CDE#TRPBF

Overview

The LTC2617CDE#TRPBF is a dual 14-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 guaranteed monotonic over temperature. The device utilizes a 2-wire I²C compatible serial interface supporting standard (100kHz) and fast (400kHz) modes, with an asynchronous DAC update pin (LDAC). It incorporates a power-on reset circuit that defaults outputs to zero scale upon initialization.

Feature Summary

• Dual 14-bit resolution with rail-to-rail voltage output in a 12-lead DFN package
• I²C interface with 27 selectable addresses and asynchronous LDAC update
• Low power consumption: 260µA per DAC at 3V, down to 1µA max in power-down mode
• High drive capability with ±15mA minimum output current and ultralow crosstalk of 30µV

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging. Confirm the C grade indicates a commercial operating temperature range of 0°C to 70°C. Ensure the absence of the -1 suffix, which would alter the power-on reset behavior to mid-scale instead of zero scale.

Selection Notes

Select this component for applications requiring dual channels with 14-bit precision and low board density. Compare against LTC2607 for higher 16-bit resolution or LTC2627 for 12-bit resolution if cost or speed is prioritized. Ensure the I²C bus capacitance does not exceed limits for 400kHz operation without active pull-ups.

Part Context

This part belongs to the LTC2607/LTC2617/LTC2627 family of pin-compatible dual DACs. They share identical footprints and interfaces, differing primarily in resolution (16, 14, and 12 bits respectively). The family establishes benchmarks for board density and output drive performance in single-supply voltage-output DACs.

Replacement Considerations

LTC2617CDE#PBF offers the same electrical specifications but in tube packaging instead of tape and reel.
