LTC1290CCJ

Analog To Digital Converters (ADC) Overview

The LTC1290CCJ is a monolithic 12-bit Data Acquisition System (DAS) manufactured by Analog Devices Inc. It integrates a high-speed sampling analog-to-digital converter (ADC), a programmable gain amplifier, and a multiplexer on a single chip. The device features a serial interface compatible with standard microprocessors and operates from a single +5V power supply. Key electrical specifications include a 12-bit resolution, a maximum sampling rate of 50ksps, and a throughput speed of 46.5ksps. The component is housed in a 20-pin CERDIP package and is designed for industrial operating temperatures ranging from 0°C to 70°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CCJ' against official Analog Devices documentation to confirm the package type (CERDIP) and temperature grade. Confirm current availability status as older ceramic DIP packages may be discontinued or subject to long lead times. Ensure compatibility with existing board layouts for the 20-pin CERDIP footprint during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1290CCJ when a complete DAS solution is required without external multiplexers or amplifiers. Compare the 50ksps throughput against higher-speed alternatives like the LTC1298 if system latency is critical. Verify that the single-supply architecture aligns with the target system's power constraints. Check input voltage ranges to ensure they match the sensor signals being acquired.

Analog To Digital Converters (ADC) Part Context

The LTC1290 belongs to the LTC129x family of 12-bit data acquisition systems. This family includes variants such as the LTC1290, LTC1291, LTC1292, and LTC1293, which differ primarily in channel count and packaging options. The LTC1290 specifically offers a balance of performance and integration for general-purpose applications requiring moderate speed and resolution.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the LTC1290BCSW#PBF (SOIC package) or LTC1290CN8 (PDIP package). Cross-family upgrades may involve the LTC1298 for higher speeds. Verify pinout compatibility and software register settings when substituting with other members of the LTC129x series.
