LTC2656BIFE-L16#TRPBF

Overview

The LTC2656BIFE-L16#TRPBF is an octal 16-bit rail-to-rail digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features a precision integrated reference with a maximum temperature coefficient of 10ppm/°C, providing a full-scale output voltage of 2.5V. The device operates on a single supply voltage ranging from 2.7V to 5.5V and communicates via a 4-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±4LSB at 16 bits, a settling time of 8.9µs for 16-bit accuracy, and guaranteed monotonicity over the operating temperature range. The component is housed in a 20-lead thermally enhanced TSSOP package.

Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to the tape and reel packaging format as specified in the manufacturer's documentation. Confirm the specific temperature grade and electrical accuracy class required for the application environment before procurement.

Selection Notes

Select this part when eight independent 16-bit voltage outputs are required within a compact footprint. Ensure the system power supply remains within the 2.7V to 5.5V range suitable for the -L option. Consider the external reference mode if a full-scale output different from 2.5V is needed, noting that the external reference voltage must be between 0.5V and VCC/2.

Part Context

This component belongs to the LTC2656 family of octal DACs, which also includes variants with different resolutions (12-bit), accuracy grades (±12LSB INL), and full-scale voltages (4.096V). The BIFE-L16 designation specifically identifies the industrial temperature grade (-40°C to 85°C), high accuracy (±4LSB), 2.5V internal reference, and TSSOP package configuration.

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2656BCFE-L16#TRPBF (commercial grade) or LTC2656BIUFD-L16#TRPBF (QFN package). Verify that any substitute maintains the required ±4LSB INL specification and thermal performance characteristics.
