LTC2752BCLX#PBF

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. Key electrical characteristics include a 1μA maximum supply current, 16-bit settling time of 2µs, and glitch impulse of 0.6nV•s at 3V. It includes voltage-controlled offset and gain adjustments, serial readback of all registers, and power-on reset functionality.

Feature Summary

• Dual 16-bit current-output DACs with software-selectable or pin-strapped output ranges
• Maximum INL error of ±1 LSB over temperature without adjustments
• Glitch impulse as low as 0.6nV•s at 3V supply
• Serial readback of all on-chip registers in one instruction cycle

Applications

• Process control and industrial automation
• Automatic test equipment
• Data acquisition systems

Procurement Notes

Verify the package type is the 48-lead 7mm × 7mm Plastic LQFP. Confirm the temperature range is 0°C to 70°C for the B grade. Ensure the ordering suffix #PBF indicates lead-free finish. Check that the shipping container label identifies the specific temperature grade.

Selection Notes

Select the LTC2752BCLX#PBF for applications requiring guaranteed ±1 LSB INL over the commercial temperature range. Choose the ILX variant if operation down to –40°C is required. Use manual span configuration by tying M-SPAN to VDD if hardware pin strapping is preferred over SPI programming for fixed ranges.

Part Context

The LTC2752 is part of the SoftSpan DAC family, which allows flexible output range selection via software or hardware. It is manufactured by Analog Devices Inc., formerly Linear Technology. The B grade offers tighter static performance specifications compared to the A grade, specifically regarding INL and gain error tolerances across the operating temperature range.
