LTC2654CUF-H12#TRPBF

Overview

The LTC2654CUF-H12#TRPBF is a quad 12-bit rail-to-rail digital-to-analog converter (DAC) in a 20-lead 4mm × 4mm QFN package. It features an integrated reference providing a full-scale output of 4.096V and operates from a 4.5V to 5.5V supply. The device communicates via a 50MHz SPI/MICROWIRE compatible interface and includes built-in high-performance output buffers guaranteed monotonic over temperature. Key electrical parameters include a maximum integral nonlinearity (INL) of ±1 LSB, offset error of ±2mV, and settling time of 4.6µs for 12-bit accuracy.

Feature Summary

Quad 12-bit resolution with integrated 4.096V reference
Rail-to-rail output buffers with ultralow crosstalk (<3nV•s)
SPI/MICROWIRE compatible 4-wire serial interface up to 50MHz
Power-on reset selectable to zero-scale or mid-scale

Applications

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

Procurement Notes

Verify the suffix #TRPBF indicates tape and reel packaging and lead-free construction. Confirm the UF package designation matches the required 20-lead QFN footprint. Ensure the H12 variant aligns with the 4.5V minimum supply requirement for the 4.096V internal reference mode.

Selection Notes

Select this part when a quad DAC configuration is required with a fixed 4.096V full-scale range. The -H suffix mandates a supply voltage between 4.5V and 5.5V. For lower voltage applications requiring a 2.5V full-scale output, consider the -L variant instead. Verify that the commercial temperature grade (0°C to 70°C) meets system environmental constraints.

Part Context

This component belongs to the LTC2654 family of precision DACs. It shares architectural similarities with the LTC2655 but utilizes a serial interface rather than I2C. The CUH12 designation specifically identifies the commercial grade, 12-bit resolution, and 4.096V reference option within the 20-lead QFN form factor.
