AD7839AS

Overview

The AD7839AS is an octal 13-bit digital-to-analog converter (DAC) featuring parallel input and voltage output. It integrates eight independent DAC channels on a single monolithic chip, utilizing an R-2R architecture with buffered outputs capable of ±10 V full-scale range from ±5 V references. The device operates with +5 V logic supply (VCC), and ±15 V analog supplies (VDD/VSS). Key electrical parameters include a maximum relative accuracy of –2 LSB, differential nonlinearity of –0.9 LSB max, and a typical settling time of 30 µs. It is housed in a 44-lead MQFP package and supports industrial temperature ranges from –40°C to +85°C.

Feature Summary

Eight 13-bit DAC channels integrated in a single 44-lead MQFP package
Parallel data interface with individual channel address selection (A0–A2)
Offset adjustment capability for each DAC pair via DUTGND pins
Clear function allows switching all outputs to a user-defined voltage level

Applications

Automatic Test Equipment (ATE) pin electronics
Process control systems requiring multi-channel voltage generation
General purpose instrumentation

Procurement Notes

Verify the specific suffix 'S' indicates the Plastic Quad Flatpack (MQFP) package option. Confirm that the component meets RoHS compliance requirements if applicable to the procurement specification. Ensure power supply sequencing adheres to the recommended order of VDD/VSS followed by VCC to prevent high current states during startup.

Selection Notes

Select this component when multiple isolated 13-bit voltage outputs are required in a compact form factor. The parallel interface necessitates sufficient microcontroller or DSP I/O lines for 13 data bits plus control signals. Consider the 30 µs settling time and 15 mA short-circuit current limits when designing load conditions for the buffered outputs.

Part Context

The AD7839AS belongs to the Analog Devices AD7839 series of octal DACs. It shares functional similarities with other members of the family but differs in resolution and interface type. For instance, the AD7834 offers 14-bit resolution with serial input, while the AD7837 provides dual 12-bit channels. The AD7839AS specifically targets applications needing eight parallel-input channels.
