Overview
The LTC2617IDE#TRPBF is a dual 14-bit rail-to-rail voltage output digital-to-analog converter (DAC) manufactured by Analog Devices Inc. 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 maximum differential nonlinearity (DNL) of ±1 LSB, integral nonlinearity (INL) of ±4 LSB, and an asynchronous DAC update pin (LDAC). The component is housed in a compact 12-lead (4mm × 3mm) plastic DFN package with an exposed ground pad.
Feature Summary
- Dual 14-bit resolution with guaranteed monotonicity over temperature
- I²C interface with 27 selectable addresses and global address support
- Rail-to-rail output drive capability of ±15mA minimum
- Power-on reset circuit ensures outputs stay at zero scale until updated
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 components. Confirm that the IDE suffix corresponds to the industrial temperature range of –40°C to 85°C. Ensure compatibility with the 12-lead DFN footprint during procurement planning.
Selection Notes
Select the LTC2617IDE#TRPBF for applications requiring dual-channel precision with 14-bit resolution. This model is suitable where board density is critical due to its small DFN package. Consider the power-down current reduction if energy efficiency is required, as individual channels can be powered down to approximately 1µA.
Part Context
This part belongs to the LTC2607/LTC2617/LTC2627 family of dual rail-to-rail DACs. The LTC2617 variant specifically provides 14-bit resolution, distinguishing it from the 16-bit LTC2607 and 12-bit LTC2627. All members share the same pinout and interface protocol, allowing for pin-compatible design flexibility across different resolution requirements.
Replacement Considerations
The LTC2617CDE#TRPBF serves as a commercial grade alternative within the same package and specification profile, differing only in the operating temperature range (0°C to 70°C). Verify thermal requirements before substituting.
