LTC2641ACDD-16#TRPBF

Overview

The LTC2641ACDD-16#TRPBF is a 16-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 supply current 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 ±1 LSB over temperature, a settling time of 1µs to 16 bits, and a glitch impulse of 0.5nV·sec. It is housed in an 8-lead 3mm × 3mm DFN package and is guaranteed monotonic over the commercial temperature range of 0°C to 70°C.

Feature Summary

• 16-bit resolution with ±1LSB INL/DNL accuracy over temperature
• Low power consumption: 120µA supply current
• Fast 1µs settling time and 0.5nV·sec glitch impulse
• Unbuffered voltage output directly drives 60kΩ loads

Applications

• Process control and industrial automation
• Automatic test equipment
• Data acquisition systems

Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging. Confirm the AC grade specifies ±1LSB INL/DNL performance. Ensure the DFN package matches the PCB footprint requirements. Check for RoHS compliance status in the specific datasheet revision.

Selection Notes

Select this part for applications requiring high linearity and low power in a small footprint. The unbuffered output requires careful consideration of load impedance to maintain accuracy. For bipolar operation, the LTC2642 variant with internal scaling resistors is required instead.

Part Context

This component belongs to the LTC2641/LTC2642 family of 16-/14-/12-bit DACs. The 'A' suffix denotes enhanced accuracy grades compared to standard parts. The 'C' indicates the commercial temperature range. The 'DD' code specifies the 8-lead 3mm x 3mm DFN package.

Replacement Considerations
