DAC7625PB

Digital To Analog Converters Overview

The DAC7625PB is a 12-bit quad voltage output digital-to-analog converter manufactured by Burr-Brown. It features four independent channels with buffered voltage outputs, supporting a parallel interface for data input. The device operates on a single 5 V analog supply and a separate 5 V digital supply. Key performance parameters include a settling time of 5 microseconds, differential nonlinearity (DNL) of +/- 1 LSB, integral nonlinearity (INL) of +/- 1 LSB, and a gain error of 0.2% FSR. It utilizes an R-2R resistor ladder structure and is housed in a 28-pin plastic dual in-line package (PDIP).

Digital To Analog Converters Feature Summary

• Four independent 12-bit channels with buffered voltage outputs.
• Parallel interface for digital data input.
• Single 5 V power supply operation for both analog and digital sections.
• R-2R resistor ladder architecture ensuring monotonicity.

Digital To Analog Converters Applications

• Process control systems requiring multi-channel signal generation.
• Portable battery-operated instruments due to low power consumption.
• Programmable voltage sources and current sources.
• Digital gain and offset voltage adjustment circuits.

Digital To Analog Converters Procurement Notes

Verify the manufacturer designation as Burr-Brown or Texas Instruments, as Burr-Brown was acquired by TI. Confirm the package type is PDIP-28 and check for suffix variations that may indicate temperature range or lead-free compliance. Ensure the specific part number matches the required pinout and electrical specifications from the official datasheet before procurement.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel, 12-bit resolution DAC with a parallel interface is required. It is suitable for applications needing buffered outputs and single-supply operation at 5 V. Compare against serial interface alternatives like the DAC7625U if pin count reduction is necessary. Verify that the 5 microsecond settling time meets the system speed requirements.

Digital To Analog Converters Part Context

The DAC7625 belongs to the Burr-Brown family of precision digital-to-analog converters. It is part of a series that includes variants such as the DAC7625P and DAC7625U, differing primarily in package style and interface type. This component represents a standard solution for multi-channel analog output applications in industrial and instrumentation fields.

Digital To Analog Converters Replacement Considerations

Direct substitutes include the DAC7625P and DAC7625U from the same product family. Verify pin compatibility and interface differences, as the U variant uses a serial interface. Cross-reference with other quad-channel 12-bit DACs if parallel interfaces are not strictly required.
