LTC1278-5CSW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1278-5CSW#PBF is a 12-bit, 500ksps sampling analog-to-digital converter (ADC) manufactured by Analog Devices. It operates from a single 5V supply and consumes only 75mW of power. The device features a fast conversion time of 1.6µs and includes an internal reference and track-and-hold amplifier. Packaged in a 24-pin SOIC, it supports parallel data output interfaces suitable for high-speed data acquisition systems requiring low power consumption and moderate resolution.

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation as Analog Devices Inc., as Linear Technology was acquired. Confirm the specific suffix -5 indicates the 5V supply variant. Check current availability status through authorized distributors, as older components may have limited stock or end-of-life notifications. Ensure the SOIC-24 package matches the design footprint requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between speed and power consumption is required for 12-bit applications. Compare against higher-resolution SAR ADCs if greater precision is needed. Verify that the parallel interface compatibility matches the host microcontroller or DSP. Consider thermal management within the SOIC-24 package for continuous operation at maximum sampling rates.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC127x family of high-speed, low-power SAR ADCs. It shares architectural similarities with the LTC1274 and LTC1277 but offers higher throughput. The -CSW#PBF designation specifies the commercial temperature range (-0°C to +70°C) and lead-free RoHS-compliant packaging in a wide SOIC format.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the LTC1277 for lower power or the LTC1274 for lower speed. Cross-vendor alternatives require verification of pinout compatibility, interface timing, and reference voltage requirements. Ensure any substitute maintains the 500ksps throughput and 12-bit linearity specifications.
