DAC7625U

Digital To Analog Converters Overview

The DAC7625U is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor string architecture to provide buffered voltage outputs. The device operates with a single 5V digital supply and dual ±5V analog supplies, consuming 15 mW of power. It features a parallel interface and supports a sampling rate of 100 kS/s. Key performance metrics include a settling time of 10 µs, a differential nonlinearity (DNL) of ±1 LSB, and an integral nonlinearity (INL) of ±2 LSB. The gain error is specified at 0.2% FSR. It functions within a temperature range of -40°C to +85°C and is housed in a 28-pin SOIC package.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout compatibility and packaging type. Ensure that the selected variant matches the required operating temperature range and supply voltage specifications for the target application environment before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a design requires four synchronized analog outputs from a single IC. Compare it against the DAC7624U if mid-scale reset functionality is needed, or consider the DAC7625UB for tape-and-reel processing requirements. Validate that the parallel interface timing meets the system clock constraints.

Digital To Analog Converters Part Context

The DAC7625U belongs to the DAC762x family of quad-channel converters from Texas Instruments. This series is designed for applications demanding multiple analog outputs without the complexity of managing separate discrete components. It shares architectural similarities with other members like the DAC7624U but differs in specific feature sets such as reset capabilities.

Digital To Analog Converters Replacement Considerations

DAC7625UB serves as the tape-and-reel equivalent. DAC7624U is a functional alternative offering mid-scale reset features. Verify pin compatibility and electrical parameters before substitution.
