LTC2654IUF-H12#PBF

Overview

The LTC2654IUF-H12#PBF is a quad 12-bit rail-to-rail digital-to-analog converter (DAC) from Analog Devices, housed in a 20-lead 4mm × 4mm plastic QFN package. It features an integrated reference providing a full-scale output of 4.096V and operates on a single 4.5V to 5.5V supply. The device includes high-performance output buffers guaranteed monotonic over temperature, with a maximum integral nonlinearity error of ±1 LSB. Communication is handled via a 4-wire SPI/Microwire compatible serial interface supporting clock rates up to 50MHz.

Feature Summary

Quad 12-bit resolution with integrated 4.096V reference
Rail-to-rail output buffers with guaranteed monotonicity
Maximum INL error of ±1 LSB
SPI/Microwire compatible 4-wire serial interface

Applications

Mobile communications
Process control and industrial automation
Instrumentation
Automatic test equipment
Automotive systems

Procurement Notes

Verify the specific ordering suffix IUF-H12#PBF against manufacturer documentation to confirm the 20-lead QFN package, industrial temperature range (-40°C to 85°C), and 12-bit resolution with 4.096V internal reference. Ensure compatibility with system voltage requirements of 4.5V to 5.5V.

Selection Notes

Select this component for applications requiring four independent 12-bit DAC channels with high precision and low offset error. The industrial temperature grade makes it suitable for environments ranging from -40°C to 85°C. Consider the external reference mode if a different full-scale voltage is required, as the external input can be up to VCC/2.

Part Context

This part belongs to the LTC2654 family of quad DACs, which also offers 16-bit resolution options and commercial temperature grades. The 'I' suffix denotes the industrial temperature range, while 'H' indicates the 4.096V full-scale output configuration derived from the internal 2.048V reference multiplied by two.
