Overview
The LTC2655BIGN-H16#TRPBF is a quad, 16-bit rail-to-rail digital-to-analog converter (DAC) from Analog Devices. It features an integrated reference with a maximum temperature coefficient of 10ppm/°C and a full-scale output voltage of 4.096V. The device operates on a single supply voltage ranging from 4.5V to 5.5V. It utilizes a 2-wire I²C compatible serial interface supporting standard mode (100kHz) and fast mode (400kHz). The DACs include built-in high-performance output buffers and are guaranteed monotonic over the operating temperature range.
Feature Summary
- Quad channel architecture with 16-bit resolution
- Integrated reference providing 4.096V full-scale output
- I²C compatible serial interface with asynchronous update pin
- Rail-to-rail output buffers with ultralow crosstalk (<1nV·s)
Applications
- Mobile communications
- Process control and industrial automation
- Instrumentation
- Automatic test equipment
- Automotive systems
Procurement Notes
Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the B grade specifies a maximum Integral Nonlinearity (INL) error of ±4LSB at 16 bits. Ensure the H designation matches the required 4.5V to 5.5V supply voltage range for the 4.096V full-scale output configuration.
Selection Notes
Select the LTC2655BIGN-H16#TRPBF when four independent 16-bit voltage outputs are required in a narrow SSOP package. This part is suitable for designs needing a precision internal reference without external components. Consider the -L variant if a lower supply voltage range (2.7V to 5.5V) and 2.5V full-scale output are acceptable. Verify I²C address configurations via CA pins if multiple devices share the bus.
Part Context
This component belongs to the LTC2655 family of quad DACs, which also includes 12-bit variants and different package options such as QFN. The 'GN' suffix denotes the 16-lead narrow SSOP package, while 'H' specifies the 4.096V full-scale version. The 'B' electrical grade ensures tighter linearity specifications compared to standard grades.
Replacement Considerations
Direct replacements within the same family include LTC2655BCUF-H16#TRPBF for QFN packaging or LTC2655BIUF-H16#TRPBF for industrial temperature ranges in QFN. For 12-bit resolution requirements, consider LTC2655CGN-H12#TRPBF.
