LTC2617IDE-1#PBF

Overview

The LTC2617IDE-1#PBF is a dual 14-bit rail-to-rail voltage output digital-to-analog converter (DAC) in a 12-lead DFN package. It operates on a single supply 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). The '-1' suffix designates a power-on reset configuration that sets outputs to mid-scale upon initialization.

Feature Summary

• Dual 14-bit resolution with rail-to-rail voltage outputs
• I²C interface with 27 selectable addresses and global address support
• Power-on reset to mid-scale for the -1 variant
• Low power consumption: 260µA per DAC at 3V, down to 1µA max in power-down

Applications

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

Procurement Notes

Verify the specific ordering suffix '#PBF' indicates lead-free finish and tube packaging. Confirm the '-1' designation matches the required mid-scale power-on reset behavior. Check current availability status as distribution may vary. Ensure the operating temperature range (-40°C to 85°C for 'I' grade) aligns with system requirements.

Selection Notes

Select this part for applications requiring dual 14-bit precision in a compact footprint. Compare against LTC2607 (16-bit) or LTC2627 (12-bit) if resolution needs differ. Consider the non-'-1' variants if zero-scale power-on reset is preferred. Verify I²C bus capacitance limits and pull-up resistor requirements for the chosen clock speed.

Part Context

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

Replacement Considerations

LTC2617IDE#PBF serves as a direct functional substitute with zero-scale power-on reset instead of mid-scale. LTC2607IDE-1#PBF and LTC2627IDE-1#PBF are pin-compatible alternatives offering higher (16-bit) or lower (12-bit) resolution respectively.
