Overview
The LTC2753BCUK-16#TRPBF is a dual-channel, 16-bit multiplying digital-to-analog converter (DAC) from Analog Devices Inc. It features SoftSpan technology, enabling six software-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 a settling time of 2μs to ±1 LSB, a glitch impulse of 1nV•s, and guaranteed monotonicity over temperature. It utilizes a bidirectional parallel interface for data input and register readback.
Feature Summary
- Dual 16-bit resolution with SoftSpan architecture supporting six programmable output ranges
- Low power consumption with maximum supply current of 1μA
- Bidirectional parallel I/O interface allowing readback of all internal registers
- Asynchronous CLR pin clears DAC outputs to 0V in any range; Power-On Reset ensures 0V start
Applications
- Process Control and Industrial Automation
- Automatic Test Equipment
- Data Acquisition Systems
Procurement Notes
Verify the #TRPBF suffix indicates tape and reel packaging. Confirm the BC grade corresponds to the commercial temperature range (0°C to 70°C) and specific gain error limits defined in the datasheet. Ensure compatibility with the 48-lead QFN footprint during procurement planning.
Selection Notes
Select this part for applications requiring high-resolution current-output DACs with flexible voltage range programming. The BC grade offers standard performance suitable for commercial environments. Consider the 48-QFN package size and thermal characteristics when designing the PCB layout.
Part Context
This component belongs to the LTC2753 family of dual SoftSpan DACs. It shares the same core architecture and pinout with other variants such as the LTC2753ACUK-16#TRPBF, differing primarily in temperature grade and precision specifications. The 'BC' designation identifies it as the commercial grade version within the 16-bit subset of the series.
Replacement Considerations
Direct functional substitutes within the same package and specification profile include the LTC2753ACUK-16#TRPBF (higher precision, commercial temp) or LTC2753BIUK-16#TRPBF (industrial temp). Verify that the replacement matches the required operating temperature range and accuracy specifications.
