LTC2381HMS-16#TRPBF

Overview

The LTC2381HMS-16#TRPBF is a 16-bit, 250ksps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 2.5V supply with a fully differential input range of ±2.5V and dissipates 3.25mW at maximum throughput. The device features an internal oscillator, SPI-compatible serial interface supporting 1.8V to 5V logic, and daisy-chain capability. Key performance metrics include ±2LSB maximum integral nonlinearity, guaranteed 16-bit no missing codes, and 92dB typical SNR. The H-grade variant supports extended operating temperatures from -40°C to +125°C.

Feature Summary

16-bit resolution with 250ksps sampling rate and 3.25mW power consumption
Fully differential ±2.5V input range with external 2.5V reference requirement
SPI-compatible serial interface with 1.8V to 5V I/O voltage support
Extended temperature operation (-40°C to +125°C) for the H-grade package

Applications

Medical imaging systems
High-speed data acquisition
Portable or compact instrumentation
Industrial process control
Low power battery-operated instrumentation

Procurement Notes

Verify that the H suffix corresponds to the -40°C to +125°C operating range required for the application. Confirm the #TRPBF suffix indicates tape and reel packaging suitable for automated assembly. Ensure the host system provides a stable 2.5V analog supply and compatible digital I/O levels between 1.8V and 5V.

Selection Notes

Select this component when high accuracy and low power are critical constraints. The extended acquisition time of 3.25µs allows the use of lower power ADC drivers compared to faster SAR ADCs. An external precision reference such as the LTC6652-2.5 is required to achieve specified dynamic performance. Verify that the system can accommodate the 16-pin MSOP or DFN package footprint.

Part Context

This part belongs to the LTC2381-16 family of low-power SAR ADCs. The 'H' designation specifies the industrial extended temperature grade (-40°C to +125°C), distinguishing it from the C (0°C to 70°C) and I (-40°C to 85°C) grades. The '#TRPBF' suffix denotes lead-free finish and tape-and-reel packaging.
