LTC2381HMS-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2381HMS-16#PBF is a 16-bit, 250ksps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. Operating from a single 2.5V supply, it features a ±2.5V fully differential input range and consumes 3.25mW at full throughput. The device guarantees 16-bit no missing codes with a maximum integral nonlinearity of ±2LSB and achieves a typical signal-to-noise ratio of 92dB at an input frequency of 20kHz. It utilizes an SPI-compatible serial interface supporting 1.8V to 5V logic levels and includes daisy-chain capability. The component is housed in a 16-lead MSOP package and is rated for operation between –40°C and 125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the H-grade suffix indicates the extended temperature range of –40°C to 125°C. Confirm the #PBF designation corresponds to lead-free finish and tube packaging for the MSOP variant. Ensure the external reference voltage matches the required 2.4V to 2.6V range for optimal performance.

Analog To Digital Converters (ADC) Selection Notes

Select this model when an extended industrial temperature range up to 125°C is required. The H-grade variant shares electrical specifications with C and I grades but offers wider thermal tolerance. Ensure the application supports the 2.5V analog supply and compatible digital I/O voltages ranging from 1.71V to 5.25V.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2381-16 family of low-power SAR ADCs. The H-grade suffix specifically denotes the high-temperature operational range compared to the commercial (C) and industrial (I) variants. All variants share identical pinouts and electrical characteristics within their respective temperature limits.
