AD5752RBREZ

Overview

The AD5752RBREZ is a dual-channel, 16-bit voltage output digital-to-analog converter (DAC) from Analog Devices. It operates on single supplies of +4.5 V to +16.5 V or dual supplies of ±4.5 V to ±16.5 V. The device features an integrated 2.5 V reference with a maximum temperature coefficient of 5 ppm/°C and software-selectable output ranges including ±10 V and ±5 V. Key performance metrics include a typical settling time of 10 μs, integral nonlinearity (INL) of ±16 LSB, and differential nonlinearity (DNL) of ±1 LSB. It utilizes a 3-wire serial interface compatible with DSP standards and is housed in a 24-lead TSSOP package.

Feature Summary

• Dual-channel 16-bit resolution with guaranteed monotonicity
• Integrated 2.5 V reference buffer with ±5 ppm/°C temperature coefficient
• Software-programmable unipolar/bipolar output ranges (+5 V, +10 V, ±5 V, ±10 V)
• 3-wire serial interface supporting clock rates up to 30 MHz

Applications

• Industrial automation systems
• Closed-loop servo control applications
• Process control instrumentation
• Programmable logic controllers (PLCs)

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm packaging details such as reel quantities. Ensure compatibility with the required supply voltage range and output load specifications before integration. Confirm moisture sensitivity level handling procedures during assembly.

Selection Notes

Select the AD5752R for applications requiring high precision dual-channel voltage outputs with integrated references. Compare INL and DNL specifications against system accuracy requirements. Verify that the 3-wire serial interface timing constraints align with the host microcontroller or DSP capabilities.

Part Context

The AD5752R belongs to the iCMOS-based AD5722R/AD5732R/AD5752R family of complete DACs. It is pin-compatible with the AD5722R (12-bit) and AD5732R (14-bit) variants. The 'B' suffix typically denotes specific performance grades within the series, while 'REZ' indicates the tape and reel packaging format in the TSSOP-24 package.

Replacement Considerations

The AD5722R and AD5732R are pin-compatible alternatives offering lower resolutions (12-bit and 14-bit, respectively). For quad-channel configurations, consider the AD5754R series. Verify that any substitute maintains the required serial interface compatibility and output drive capability.
