LTC2657BCUFD-H16#TRPBF

Overview

The LTC2657BCUFD-H16#TRPBF is an octal 16-bit digital-to-analog converter featuring a 4mm × 5mm QFN package. It integrates a precision reference yielding a 4.096V full-scale output and operates on a 4.5V to 5.5V supply. The device utilizes a 2-wire I²C interface supporting up to 400kHz clock rates. Key electrical specifications include a maximum integral nonlinearity (INL) of ±4 LSB, guaranteed monotonicity, and a typical settling time of 9.1µs for 16-bit accuracy. Supply current is 3.3mA with the internal reference active.

Feature Summary

Octal architecture with eight independent 16-bit voltage outputs
Integrated 2.048V reference providing 4.096V full-scale range
Maximum INL error of ±4 LSB over temperature
I²C serial interface with selectable slave addresses via CA pins

Applications

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

Procurement Notes

Verify the specific suffix H16 corresponds to the 4.096V full-scale option requiring a 4.5V minimum supply. Confirm the B grade indicates the ±4LSB INL specification. Ensure the UFD package matches the 20-lead QFN footprint requirements. Check tape and reel specifications for automated assembly compatibility.

Selection Notes

Select this part when eight isolated DAC channels are required in a compact form factor. The H-option is necessary for applications demanding a 4.096V output swing, provided the system supply supports at least 4.5V. The B-grade offers standard linearity performance suitable for general-purpose control loops. Consider the L-option if a lower 2.7V supply voltage is available.

Part Context

This component belongs to the LTC2657 family of rail-to-rail DACs. The BC designation identifies the commercial temperature grade (0°C to 70°C). The UFD suffix specifies the plastic QFN package type. The TRPBF suffix indicates tape and reel packaging with lead-free finish.
