Overview
The LTC2641CDD-12#PBF is a 12-bit unbuffered voltage output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.7V to 5.5V supply with a typical current consumption of 120µA. The device features a 3-wire SPI/Microwire compatible serial interface supporting clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) and differential nonlinearity (DNL) of ±0.5 LSB, a settling time of 1µs to 0.5 LSB, and a glitch impulse of 0.5 nV·sec. It is housed in an 8-lead 3mm × 3mm DFN package and is guaranteed monotonic over temperature.
Feature Summary
- 12-bit resolution with ±0.5 LSB INL/DNL accuracy
- Low power consumption of 120µA at 2.7V–5.5V
- Fast 1µs settling time to 0.5 LSB
- Unbuffered voltage output driving loads >60kΩ
Applications
- Process control and industrial automation
- Automatic test equipment
- Data acquisition systems
Procurement Notes
Verify the specific suffix #PBF indicates lead-free finish and tube packaging as per the manufacturer's ordering information. Confirm the commercial temperature grade (0°C to 70°C) matches the application requirements. Ensure the 8-lead DFN footprint aligns with the PCB layout guidelines provided in the datasheet.
Selection Notes
Select this model for applications requiring low power and moderate precision. Note that the unbuffered output has a source resistance of approximately 6.2kΩ; ensure load impedance remains above 60kΩ to maintain linearity. For bipolar operation, the LTC2642 variant is required instead of the LTC2641.
Part Context
This component belongs to the LTC2641/LTC2642 family of voltage output DACs. The '12' in the part number denotes the 12-bit resolution version. Other variants in the series offer 14-bit and 16-bit resolutions with corresponding adjustments in linearity error specifications and power consumption profiles.
Replacement Considerations
The LTC2641CDD-12#TRPBF is the tape and reel equivalent of this part. For higher resolution needs within the same package, consider the LTC2641CDD-14#PBF or LTC2641CDD-16#PBF.
