LTC2301HMS#PBF

Analog To Digital Converters (ADC) Overview

The LTC2301HMS#PBF is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) featuring an I²C compatible serial interface. It operates from a single 5V supply, drawing 300μA at a throughput rate of 1ksps and consuming 1.5mW. The device includes an internal 2.5V reference and a fully differential sample-and-hold circuit. Key electrical parameters include a 14ksps maximum sampling rate, a conversion time of 1.3μs, and a signal-to-noise ratio (SNR) of 73.5dB at 1kHz input frequency. It supports unipolar or bipolar input ranges via software selection.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'H' suffix indicates the extended temperature range of –40°C to 125°C. Confirm the '#PBF' suffix denotes lead-free finish and tube packaging. Ensure compatibility with the 12-lead Plastic MSOP package dimensions. Check for obsolescence status as some variants may be discontinued.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2301HMS#PBF for single-channel applications requiring high accuracy and low power. The 'H' grade is necessary for environments exceeding 85°C. Compare against the LTC2305 if two independent channels are required instead of one channel with polarity reversal capability.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2301/LTC2305 family of low noise, low power ADCs. The 'HMS' designation specifies the industrial/high-temperature grade housed in a 12-pin MSOP package. It shares the same core architecture and interface as the commercial (C) and industrial (I) grades but offers extended thermal operation.
