LTC2752ACLX#PBF

Overview

The LTC2752ACLX#PBF is a dual 16-bit multiplying serial-input current-output digital-to-analog converter manufactured by Analog Devices. It operates from a single 2.7V to 5.5V supply and features SoftSpan technology, allowing six software-selectable output ranges (0V to 5V, 0V to 10V, –2.5V to 7.5V, ±2.5V, ±5V, ±10V) or manual pin-strapping. The device guarantees monotonicity over temperature with a maximum INL of ±1 LSB for the 'A' grade. Key electrical characteristics include a 1μA maximum supply current, 2μs settling time, and voltage-controlled offset and gain trim capabilities. It integrates a power-on reset circuit that clears outputs to 0V.

Feature Summary

• Dual 16-bit resolution with guaranteed monotonicity over temperature
• SoftSpan technology enables six selectable output ranges via SPI or hardware pins
• Maximum integral nonlinearity (INL) of ±1 LSB across the operating temperature range
• Ultra-low power consumption with 1μA maximum supply current

Applications

• Process control and industrial automation systems
• Automatic test equipment requiring high precision
• Data acquisition systems with multi-channel requirements

Procurement Notes

Verify the specific temperature grade associated with the ordering suffix. The 'A' designation indicates a commercial temperature range of 0°C to 70°C. Confirm package availability in trays as specified for this component family. Ensure the application supports the required 48-lead LQFP footprint and voltage levels.

Selection Notes

Select the LTC2752ACLX#PBF when a dual-channel solution with 16-bit accuracy and low power is required. Choose this part over the 'B' grade if strict ±1 LSB INL performance is necessary across the full commercial temperature range. Consider the manual span configuration option if software overhead for range switching is undesirable.

Part Context

This component belongs to the LTC2752 series of SoftSpan DACs. The 'A' suffix denotes the commercial temperature grade (0°C to 70°C), while the 'I' suffix would indicate an industrial grade (-40°C to 85°C). The 'CLX' indicates the plastic LQFP package and tray packaging. It is part of Linear Technology's portfolio, now under Analog Devices.

Replacement Considerations

The LTC2752AILX#PBF serves as the industrial temperature version of this component. For quad-channel applications, the LTC2754 series is available. Dual-channel alternatives with different resolutions include the LTC2751 (18-bit) or LTC2753 (18-bit).
