LTC2312HTS8-12#WTRPBF

Analog To Digital Converters (ADC) Overview

The LTC2312HTS8-12#WTRPBF is a 12-bit, 500ksps serial sampling Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc. 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 + Distortion) Ratio (SINAD) of 72.7dB and Total Harmonic Distortion (THD) of –84dB at 500ksps throughput. It utilizes a high-speed SPI-compatible serial interface supporting digital logic levels from 1.8V to 5V via the OVDD pin. The component is housed in an 8-lead TSOT-23 package and is qualified for automotive applications under AEC-Q100 standards.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #WTRPBF indicates the Tape and Reel packaging format with Automotive grade qualification. Confirm that the HT designation corresponds to the extended operating temperature range of –40°C to 125°C. Ensure compatibility with the required analog supply voltage range of 2.7V to 5.25V and digital I/O supply range of 1.71V to 5.25V during component sourcing.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 500ksps sampling rate are required within a compact TSOT-23 footprint. It is suitable for systems needing low power consumption with automatic nap mode functionality. Consider the separate OVDD supply for flexible digital interface voltage levels. Verify that the input signal range matches the internal reference output of 2.048V or 4.096V depending on the VDD level.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2312-12 family of 12-bit SAR ADCs. It shares pin compatibility with other members such as the LTC2313-12 and LTC2315-12, which offer higher sampling rates. The #W suffix denotes automotive-grade manufacturing controls. The HT variant specifically supports the industrial and automotive temperature range up to 125°C junction temperature.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the LTC2313-12 and LTC2315-12 for higher throughput needs. For non-automotive applications, the standard tape and reel versions without the W suffix may be considered if automotive qualification is not required.
