LTC2657CFE-H12

Overview

The LTC2657CFE-H12 is an octal, 12-bit digital-to-analog converter (DAC) from Analog Devices Inc. It features rail-to-rail buffered voltage outputs and a high-precision internal reference with a maximum temperature coefficient of 10ppm/°C. The device communicates via a 2-wire I2C interface and operates on a single supply voltage ranging from 4.5V to 5.5V. Key electrical specifications include a settling time of 9.1µs, a differential nonlinearity (DNL) of ±0.3 LSB, and an integral nonlinearity (INL) of ±2 LSB. It is housed in a TSSOP-20 package.

Feature Summary

Octal architecture providing eight independent 12-bit DAC channels
Integrated precision reference with 10ppm/°C maximum temperature coefficient
Rail-to-rail buffered voltage outputs guaranteed monotonic
I2C serial interface for simplified system connectivity

Applications

Multi-channel data acquisition systems
Programmable gain amplifiers
Process control instrumentation
Battery-powered test equipment

Procurement Notes

Verify the specific suffix 'H12' indicates the integrated 4.096V reference variant when sourcing. Confirm the 'CFE' package designation corresponds to the TSSOP-20 form factor required for the target PCB layout. Ensure compatibility with the 4.5V to 5.5V operating voltage range during procurement planning.

Selection Notes

Select this component for applications requiring multiple low-cost, precise voltage outputs controlled by a microcontroller. The 12-bit resolution and ±2 LSB INL are suitable for general-purpose analog signal generation. Consider the TSSOP-20 package constraints if board space is limited compared to QFN alternatives.

Part Context

This part belongs to the LTC2657 family of octal DACs. It shares core specifications with variants like the LTC2657BIFE-H16 but differs in resolution (12-bit vs 16-bit) and specific performance grades. It serves as a cost-effective solution for multi-channel applications where ultra-high precision is not the primary requirement.

Replacement Considerations

Direct pin-compatible substitutes within the same family include the LTC2657BIFE-H12 or LTC2657CUFE-H12, depending on the required accuracy grade. For higher resolution needs, the LTC2657BIUFD-L16 offers 16-bit performance in a QFN package, though physical footprint changes are required.
