Overview
The LTC2627IDE#TRPBF is a dual 12-bit, rail-to-rail voltage output Digital-to-Analog Converter (DAC) featuring an I²C serial interface. It operates on a single supply voltage ranging from 2.7V to 5.5V and is housed in a compact 12-lead, 4mm × 3mm DFN package. The device incorporates high-performance output buffers capable of sourcing or sinking at least ±15mA. Key electrical specifications include a maximum Differential Nonlinearity (DNL) of ±0.5 LSB and Integral Nonlinearity (INL) of ±1.5 LSB. It supports I²C clock rates up to 400kHz and offers selectable chip addresses via hardware pins.
Feature Summary
- Dual 12-bit resolution with guaranteed monotonicity over the operating temperature range
- I²C compatible serial interface supporting standard (100kHz) and fast (400kHz) modes
- Rail-to-rail output drive capability with minimum ±15mA source/sink current
- Power-on reset circuitry defaults outputs to zero scale upon power-up
Applications
- Mobile communications systems
- Process control and industrial automation equipment
- General-purpose instrumentation
- Automatic test equipment
Procurement Notes
Verify that the component matches the specific -IDE suffix for the industrial temperature range (-40°C to 85°C). Confirm the #TRPBF designation indicates tape and reel packaging. Ensure the ordering information aligns with the manufacturer's current lead-free finish specifications.
Selection Notes
Select this model when a dual-channel DAC with 12-bit resolution is required within a minimal footprint. It is suitable for applications needing rail-to-rail output swing and low power consumption, drawing approximately 260µA per DAC channel at 3V. Consider the LTC2617 or LTC2607 if higher resolution (14-bit or 16-bit) is necessary.
Part Context
This part belongs to the LTC2607/LTC2617/LTC2627 family of dual DACs. While pin-compatible, the family members differ by resolution: LTC2607 (16-bit), LTC2617 (14-bit), and LTC2627 (12-bit). All share the same 12-lead DFN package and I²C interface architecture.
Replacement Considerations
Direct replacements within the same family include the LTC2617IDE#TRPBF and LTC2607IDE#TRPBF, which offer higher resolutions but maintain identical pinouts and functionality.
