LTC2657CFE-L12#PBF

Overview

The LTC2657CFE-L12#PBF is an octal, 12-bit digital-to-analog converter (DAC) from Analog Devices Inc., housed in a 20-lead thermally enhanced TSSOP package. It features rail-to-rail output buffers and an integrated reference providing a full-scale output of 2.5V. The device operates on a single supply voltage ranging from 2.7V to 5.5V and utilizes a 2-wire I²C compatible serial interface supporting standard mode (100kHz) and fast mode (400kHz). Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, guaranteed monotonicity over temperature, and a typical settling time of 3.9µs for ±1LSB accuracy at the 12-bit resolution.

Feature Summary

Octal architecture with eight independent 12-bit DAC channels
Integrated 1.25V reference yielding a 2.5V full-scale output range
Rail-to-rail output buffers with ultralow crosstalk (0.8nV•s)
Selectable power-on reset to zero-scale or mid-scale via PORSEL pin

Applications

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

Procurement Notes

Verify the specific ordering suffix CFE-L12#PBF against official Analog Devices documentation to confirm the commercial temperature grade, 12-bit resolution, and tube packaging format. Ensure compatibility with the required I²C address configuration using CA0, CA1, and CA2 pins before procurement.

Selection Notes

Select this component when an octal DAC configuration is required with a fixed 2.5V internal reference span. The L12 designation indicates 12-bit resolution; choose the H12 variant if a 4.096V full-scale output is needed instead. Verify that the operating environment remains within the 0°C to 70°C commercial temperature range specified for the 'C' grade.

Part Context

This part belongs to the LTC2657 family of octal I²C DACs. It shares the same physical footprint and interface protocol as other variants like the LTC2657IFE-L12#PBF (industrial grade) and LTC2657BCFE-L16#PBF (16-bit resolution), allowing for potential design flexibility regarding accuracy and temperature performance while maintaining board layout consistency.
