LTC1290DCJ

Analog To Digital Converters (ADC) Overview

The LTC1290DCJ is a single-chip 12-bit data acquisition system (DAS) manufactured by Analog Devices Inc. It integrates a high-speed successive approximation analog-to-digital converter (ADC), a dual operational amplifier, and a track-and-hold amplifier on a single monolithic die. The device operates from a single +5V power supply and features a sampling rate of 60ksps. It utilizes a serial/parallel interface for data output and is housed in an 8-pin CERDIP package. The component supports unipolar or bipolar conversion modes with differential or single-ended inputs.

Analog To Digital Converters (ADC) Part Context

The LTC1290 belongs to the LTC129x family of low-power, single-supply data acquisition systems. This series is designed to provide complete signal conditioning and digitization in a compact form factor, reducing board space and component count compared to discrete solutions.

Analog To Digital Converters (ADC) Replacement Considerations

Verified direct replacements include the LTC1290BISW#TRPBF and LTC1290CISW#TRPBF. These variants offer equivalent electrical performance but differ in packaging (SOIC vs. CERDIP) and temperature grade specifications.
