LTC2758BILX

Digital To Analog Converters Overview

The LTC2758BILX is an 18-bit, dual-channel digital-to-analog converter (DAC) from Analog Devices Inc., housed in a 48-LQFP package. It operates on analog and digital supply voltages ranging from 2.7V to 5.5V. The device features current outputs without buffers and supports differential output configurations. Key performance metrics include a typical settling time of 2.1µs, maximum integral nonlinearity (INL) of ±2 LSB, and maximum differential nonlinearity (DNL) of ±1 LSB. It utilizes an SPI interface for data communication and functions within a temperature range of -40°C to 85°C.

Digital To Analog Converters Applications

• Data acquisition systems requiring high precision
• Industrial process control instrumentation
• Medical equipment signal generation
• Test and measurement devices

Digital To Analog Converters Procurement Notes

Verify the specific suffix #PBF for lead-free compliance when ordering. Confirm the package type is 48-LQFP (7x7 mm). Check the manufacturer's datasheet for humidity sensitivity handling requirements during storage and assembly. Ensure voltage supplies remain within the 2.7V to 5.5V range for both analog and digital domains.

Digital To Analog Converters Selection Notes

Select this component for applications needing two independent 18-bit current-output DACs with low power usage. Compare against single-channel variants like the LTC2757 if only one channel is required. Consider the LTC2755 family if parallel I/O interfaces are preferred over SPI. Verify that the 2.1µs settling time meets system speed requirements.

Digital To Analog Converters Part Context

The LTC2758 belongs to the SoftSpan™ DAC family, which emphasizes low power and high accuracy. It is part of a broader portfolio including the LTC2757 (single channel) and LTC2755 (parallel interface). The DC1684A-A demonstration board is available for evaluating this specific IC's performance in practical circuits.

Digital To Analog Converters Replacement Considerations

The LTC2757BILX#PBF offers similar electrical characteristics but provides only a single channel instead of dual. For parallel interface requirements, the LTC2755 series may serve as an alternative. Verify pin compatibility and software register maps before substituting any cross-model components.
