LTC2312HTS8-12#PBF

Analog To Digital Converters (ADC) Overview

The LTC2312HTS8-12#PBF is a 12-bit, 500ksps serial sampling Analog-to-Digital Converter (ADC) housed in an 8-lead TSOT-23 package. It operates from a single 3V or 5V analog supply and features an integrated low-drift reference with a maximum temperature coefficient of 20ppm/°C. The device achieves a Signal-to-Noise Ratio (SNR) of 73dB and a Total Harmonic Distortion (THD) of –84dB at 500ksps throughput. It supports a separate 1.8V to 5V digital I/O supply (OVDD) for logic compatibility. Power consumption is 15mW at 500ksps with a 5V supply, dropping to nap mode automatically after conversion.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and tube packaging when sourcing. Confirm the HT grade corresponds to the –40°C to 125°C operating temperature range required for the application environment. Ensure ordering documentation matches the exact part number to avoid confusion with automotive or tape-and-reel variants.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high sample rates with low power dissipation in compact packages. The separate OVDD pin allows flexibility in interfacing with various microcontroller logic levels. Consider the internal reference voltage span based on the chosen VDD supply level for optimal input range utilization.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2312 family of 12-bit SAR ADCs. It shares pin compatibility with other members like the LTC2313 and LTC2314 series, which offer higher speeds but different power profiles. The H-grade designation specifically denotes the extended industrial temperature range capability compared to standard commercial grades.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the LTC2313-12 for higher throughput requirements. Verify that any substitute maintains the required 500ksps performance and thermal characteristics if upgrading speed is not necessary.
