LTC2313CTS8-12

Analog To Digital Converters (ADC) Overview

The LTC2313CTS8-12 is a 12-bit, 500ksps serial sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. Housed in an 8-lead TSOT-23 package, this component integrates a high-speed successive approximation register (SAR) architecture with a track-and-hold amplifier. It operates on a single 2.7V to 5.5V supply and features a flexible serial interface compatible with standard SPI, QSPI, MICROWIRE, and DSP standards. The device offers low power consumption and high accuracy, making it suitable for battery-powered applications requiring compact form factors.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CTS8' indicates the commercial temperature range and TSOT-23 package variant. Confirm '#PBF' or '#TRMPBF' designations for lead-free compliance and reel/tape packaging requirements against current distributor listings. Check for obsolescence status as Linear Technology products may have transitioned timelines under Analog Devices.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2313CTS8-12 when a balance of moderate speed (500ksps) and high resolution (12-bit) is required in a minimal footprint. Compare against the LTC2314 series if higher speeds are needed, or the LTC2360 series for lower power at reduced speeds. Ensure the input voltage range matches the application's signal levels, as this part accepts unipolar or bipolar inputs within the supply rails.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2313 family of serial sampling ADCs from Linear Technology, now part of Analog Devices. The family includes variants like the LTC2313-14 (14-bit) and LTC2312-12 (different pinout/package). The CTS8 designation specifically refers to the 8-lead TSOT-23 thin-shrink small outline package, distinguishing it from MSOP or DFN options found in other ADC models.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same package include the LTC2313-14#TRMPBF for higher resolution or the LTC2312HTS8-12#WPBF for similar performance in a slightly different package variant. Verify interface compatibility and power specifications before substituting.
