Overview
The LTC2753AIUK-16#TRPBF is a dual 16-bit multiplying current-output DAC in a 48-lead 7mm × 7mm QFN package. It features SoftSpan technology with six programmable output ranges: two unipolar (0V to 5V, 0V to 10V) and four bipolar (±2.5V, ±5V, ±10V, –2.5V to 7.5V). The device operates on a single 2.7V to 5.5V supply with a maximum supply current of 1μA. Key electrical specifications include ±1 LSB INL and DNL over temperature, a settling time of 2μs to ±1 LSB, and a glitch impulse of 1nV•s. It utilizes a bidirectional parallel interface for register readback and includes power-on reset and asynchronous clear functions.
Feature Summary
- Dual 16-bit resolution with ±1 LSB INL/DNL guaranteed over temperature
- Six programmable output ranges via software or pin strapping
- Bidirectional parallel I/O interface with full register readback capability
- Low power consumption with 1μA maximum supply current
Applications
- Process control and industrial automation systems
- Automatic test equipment
- Data acquisition systems
Procurement Notes
Verify the #TRPBF suffix indicates tape and reel packaging. Confirm the AIUK designation corresponds to the industrial temperature range (-40°C to 85°C). Ensure compatibility with the 48-lead QFN footprint during procurement planning.
Selection Notes
Select this part for applications requiring high precision (16-bit) and low power in a compact form factor. The SoftSpan feature allows flexible voltage range configuration without external resistor changes. Verify that the parallel interface timing requirements align with the host microcontroller's capabilities.
Part Context
This component belongs to the LTC2753 family of SoftSpan DACs. The 'A' grade ensures superior linearity performance compared to lower grades. The 'I' suffix denotes the industrial temperature range. The 'UK' package code identifies the 48-lead plastic QFN housing.
Replacement Considerations
Direct replacements within the same package and specification include other LTC2753 variants such as LTC2753ACUK-16#TRPBF or LTC2753BCUK-16#TRPBF, noting differences in temperature grade and accuracy specifications.
