Overview
The Analog Devices LTC2641IMS8-12#TRPBF is a 12-bit unbuffered voltage output digital-to-analog converter (DAC) housed in an 8-lead MSOP package. It operates from a single 2.7V to 5.5V supply with a typical supply current of 120µA. The device features a 3-wire SPI/Microwire compatible serial interface supporting clock rates up to 50MHz and includes a power-on reset circuit that clears the DAC output to zero scale. Key electrical specifications include a settling time of 1µs to ±0.5LSB, a glitch impulse of 0.5nV·sec, and differential/integral nonlinearity errors of ±0.5LSB. It is guaranteed monotonic over temperature and functions within a commercial range of 0°C to 70°C.
Feature Summary
- 12-bit resolution with ±0.5LSB DNL/INL error
- Low 120µA supply current consumption
- Fast 1µs settling time to full-scale accuracy
- Unbuffered voltage output driving loads >60kΩ
Applications
- Process control and industrial automation
- Automatic test equipment
- Data acquisition systems
Procurement Notes
Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the IMS8 designation corresponds to the 8-lead MSOP package. Ensure the specific temperature grade matches the design requirements, as this part number specifies the commercial operating range.
Selection Notes
Select this component when a low-power, high-speed 12-bit DAC is required in a compact surface-mount package. The unbuffered output architecture minimizes offset and power consumption but requires careful consideration of load impedance to maintain linearity. Verify that the external reference voltage falls within the 2V to VDD range.
Part Context
This part belongs to the LTC2641 family of 16-, 14-, and 12-bit voltage output DACs. The IMS8-12 variant specifically denotes the 12-bit resolution version in the MSOP package. Other variants in the series offer higher resolutions or different packages such as the 3mm x 3mm DFN.
Replacement Considerations
Direct pin-compatible replacements within the same family include LTC2641IMS8-14#TRPBF (14-bit) and LTC2641IMS8-16#TRPBF (16-bit). These share identical interfaces and pinouts but differ in resolution and linearity specifications.
