LTC2641IDD-14#TRPBF

Overview

The LTC2641IDD-14#TRPBF is a 14-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 ±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 the industrial temperature range of -40°C to +85°C.

Feature Summary

14-bit resolution with ±0.5 LSB INL/DNL guarantees
Low power consumption: 120µA typical supply current
Fast 1µs settling time to 16-bit accuracy
Unbuffered voltage output drives loads >60kΩ directly

Applications

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

Procurement Notes

Verify that the #TRPBF suffix indicates tape and reel packaging rather than tube packaging. Confirm the specific temperature grade corresponds to the industrial range (-40°C to +85°C) required for the application environment. Ensure the order quantity aligns with standard reel sizes if bulk procurement is necessary.

Selection Notes

Select this model when 14-bit precision is sufficient and low power consumption is critical. The unbuffered output requires careful consideration of load impedance; ensure the connected circuit presents a load greater than 60kΩ to maintain specified linearity errors without degrading performance through gain error.

Part Context

This component belongs to the LTC2641/LTC2642 family of SoftSpan DACs. The LTC2641 variant provides unipolar output, whereas the LTC2642 includes internal scaling resistors for bipolar operation with external amplifiers. The IDD suffix denotes the industrial temperature grade, while the 14 indicates the 14-bit resolution version within the product line.
