LTC1272-3CCN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1272-3CCN#PBF is a 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Linear Technology. It features a sampling rate of 250kHz and a maximum conversion time of 3µs. The device operates with an analog input voltage range from -0.3V to 15V and exhibits a maximum linear error of 0.012%. It utilizes parallel word output in binary or offset binary format. Packaged in a 24-pin ceramic dual in-line package (CDIP), it supports an operating temperature range up to 70°C.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with 250kHz sampling frequency
• 3µs maximum conversion time
• Parallel access interface with binary/offset binary output
• 0.012% maximum linear error

Analog To Digital Converters (ADC) Applications

• Data acquisition systems
• Industrial process control
• Battery-powered instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance status according to manufacturer documentation. Confirm the CDIP-24 ceramic package availability as surface-mount alternatives may exist within the same family. Check for RoHS certification status, as earlier Linear Technology batches may not be compliant.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 250kHz throughput are required with parallel data output. Ensure the system can accommodate the 24-pin DIP footprint. Compare against the LTC1272-8ACJ if slower conversion speeds (8µs) are acceptable for lower power consumption.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1272 series of micropower 12-bit ADCs. It shares architectural similarities with the LTC1272-3BCN but differs in packaging material, using ceramic instead of plastic. It serves as a mid-speed alternative to higher-performance devices like the LTC1412.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements include other variants in the LTC1272 family such as LTC1272-3ACN or LTC1272-3CCSW, provided the package type matches or is adapted.
