LTC2752BCLX

Overview

The LTC2752BCLX#PBF is a dual 16-bit multiplying serial-input current-output digital-to-analog converter (DAC) from Analog Devices Inc. It operates on a single 2.7V to 5.5V supply and features SoftSpan technology, allowing six selectable output ranges: 0V to 5V, 0V to 10V, –2.5V to 7.5V, ±2.5V, ±5V, and ±10V. The device guarantees monotonicity over temperature with a maximum integral nonlinearity (INL) error of ±1 LSB for the B-grade variant. Key electrical specifications include a 1μA maximum supply current, 16-bit settling time of 2µs, and glitch impulse of 0.6nV•s at 3V. It integrates voltage-controlled offset and gain adjustments, power-on reset, and a clear pin.

Feature Summary

• Dual 16-bit resolution with guaranteed monotonicity over temperature
• SoftSpan technology enabling software-programmable or pin-strapped selection of six output ranges
• Maximum INL error of ±1 LSB (LTC2752B grade) without external adjustments
• Serial SPI interface with full register readback capability

Applications

• Process control and industrial automation systems
• Automatic test equipment requiring high precision
• Data acquisition systems needing multi-channel signal generation

Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and RoHS compliance. Confirm the temperature range corresponds to the 'C' suffix (0°C to 70°C). Ensure the package matches the 48-lead 7mm × 7mm LQFP specification. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm availability and datasheet revisions.

Selection Notes

Select the LTC2752BCLX#PBF for applications requiring ±1 LSB INL performance within the commercial temperature range. Choose the ILX variant if operation down to –40°C is required. Consider the manual span configuration via M-SPAN pin if fixed output ranges are sufficient to reduce software overhead. Ensure external reference voltages align with the desired output span multiples.

Part Context

The LTC2752 belongs to the SoftSpan DAC family, designed for high-resolution analog signal generation. The BCLX designation specifies the B-grade accuracy, commercial temperature range, and LQFP packaging. This component serves as a precision interface between digital control systems and analog actuators or sensors in industrial environments.
