LTC2641ACDD-16#PBF

Overview

The LTC2641ACDD-16#PBF 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 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 ±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 guarantees monotonic operation across the commercial temperature range of 0°C to +70°C.

Feature Summary

16-bit resolution with ±1LSB INL/DNL guaranteed over temperature
Low power consumption of 120µA with unbuffered voltage output
Fast 1µs settling time and 0.5nV·sec glitch impulse
50MHz SPI/QSPI/Microwire compatible serial interface

Applications

Process control and industrial automation
Automatic test equipment
Data acquisition systems

Procurement Notes

Verify the specific ordering suffix '#PBF' indicates lead-free finish and tube packaging. Confirm the 'C' grade corresponds to the 0°C to +70°C commercial operating temperature range. Ensure the 'DD' suffix matches the required 8-lead 3mm × 3mm DFN package for the design.

Selection Notes

Select this component for applications requiring high linearity (±1LSB) and low power in a compact footprint. The unbuffered output requires loads greater than 60kΩ to maintain specified linearity; use an external buffer if driving lower impedances. Compare against the industrial grade (IDD) variant if operation below 0°C or above 70°C is required.

Part Context

This part belongs to the LTC2641 family of 16-/14-/12-bit VOUT DACs. The 'A' designation denotes enhanced accuracy specifications compared to standard grades. It is distinct from the LTC2642, which supports bipolar output configurations via internal scaling resistors.
