LTC2617CDE-1#PBF

Overview

The LTC2617CDE-1#PBF is a dual 14-bit, rail-to-rail voltage output digital-to-analog converter (DAC) from Analog Devices. It operates on a single supply of 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. Key electrical parameters include a settling time of 9µs, ±1 LSB differential nonlinearity (DNL), and ±4 LSB integral nonlinearity (INL). Supply current is 0.52mA at 3V. The -1 suffix designates a power-on reset state set to mid-scale.

Feature Summary

• Dual 14-bit resolution with rail-to-rail voltage outputs in a 12-lead DFN package
• I²C interface with 27 selectable addresses and asynchronous LDAC update pin
• Power-on reset circuit sets outputs to mid-scale upon initialization
• Low power consumption: 260µA per DAC at 3V, down to 1µA max in power-down mode

Applications

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

Procurement Notes

Verify the ordering suffix #PBF indicates tube packaging for this specific part number. Confirm the CDE designation corresponds to the commercial temperature range (0°C to 70°C) and the DE12 package type. Ensure the -1 suffix requirement aligns with system designs needing mid-scale power-on reset behavior rather than zero-scale.

Selection Notes

Select the LTC2617CDE-1#PBF when 14-bit resolution is required alongside dual-channel operation. The -1 variant is necessary if the application demands mid-scale output initialization during power-up. Compare against the LTC2607 for higher 16-bit precision or the LTC2627 for 12-bit performance if cost or speed optimization is prioritized.

Part Context

This component belongs to the LTC2607/LTC2617/LTC2627 family of dual DACs sharing identical pinouts and interfaces. The LTC2617 specifically provides 14-bit resolution, bridging the gap between the 12-bit LTC2627 and 16-bit LTC2607. All variants share the same 12-lead DFN footprint and I²C communication protocol.
