DAC7715U/1K

Digital To Analog Converters Overview

The DAC7715U/1K is a quad, serial input, 12-bit voltage output digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor ladder architecture to achieve high precision with a gain error of 0.05% FSR and integral/differential nonlinearity of ±1 LSB. The device operates on dual power supplies ranging from 14.25 V to 15.75 V for both analog and digital sections. Key performance metrics include a settling time of 10 µs and a sampling rate of 89 kS/s per channel. It is housed in a 16-SOIC surface-mount package and supports an operating temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels within a single compact package.
• Features a reset function that returns outputs to mid-scale upon initialization.
• Supports serial data interfaces for efficient microcontroller connectivity.
• Delivers buffered voltage outputs suitable for driving external loads directly.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable power supply architectures
• Data acquisition systems with analog output capabilities

Digital To Analog Converters Procurement Notes

Verify the specific suffix '1K' indicates reel packaging containing 1000 units, distinct from tube-packaged variants like DAC7715U. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly line. Ensure the ordering part number matches the exact package and quantity needs to avoid substitution errors during procurement.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel solution is required with 12-bit resolution and bipolar supply voltages around ±15V. Compare against the DAC7714UB if only three channels are needed or if pinout compatibility is critical. Verify that the 10 µs settling time meets the system's throughput requirements at the 89 kS/s sampling rate.

Digital To Analog Converters Part Context

This part belongs to the DAC7715 family of precision digital-to-analog converters. It shares architectural similarities with the DAC7615 series but differs significantly in supply voltage requirements, supporting higher bipolar rails compared to the single-supply operation of the DAC7615. The device serves as a bridge between digital control logic and analog actuator environments.

Digital To Analog Converters Replacement Considerations

The DAC7715UBG4 is listed as a parameter-equivalent alternative. Check for availability of the DAC7714UB if channel count reduction is acceptable. Verify pin-to-pin compatibility before substituting any variant within the DAC771x family.
