LTC2381IMS-16#TRPBF

Overview

The LTC2381IMS-16#TRPBF is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 2.5V supply and features a ±2.5V fully differential input range. The device delivers a throughput rate of 250ksps with no cycle latency, consuming 3.25mW at maximum sampling speed. Key performance metrics include a typical signal-to-noise ratio (SNR) of 92dB, integral nonlinearity (INL) of ±2LSB maximum, and guaranteed 16-bit resolution without missing codes. It utilizes an SPI-compatible serial interface supporting 1.8V to 5V logic levels.

Feature Summary

16-bit resolution with 250ksps throughput and no pipeline delay
Low power consumption: 3.25mW at 250ksps, scaling down to 13µW at 1ksps
Fully differential input range of ±2.5V with external 2.5V reference requirement
SPI-compatible serial interface with daisy-chain mode support for 1.8V–5V I/O

Applications

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

Procurement Notes

Verify the IMS suffix indicates an industrial temperature range of –40°C to 85°C. Confirm the #TRPBF suffix denotes tape and reel packaging. Ensure the host system provides a stable 2.5V analog supply and compatible digital I/O voltage within the 1.71V to 5.25V OVDD range.

Selection Notes

Select this component when a low-power, high-speed 16-bit ADC with differential inputs is required. The extended 3.25µs acquisition time allows the use of lower power driver amplifiers. Ensure the application can accommodate an external voltage reference, as the device does not contain an internal one.

Part Context

This part belongs to the LTC2381-16 family of SAR ADCs. The IMS variant specifies the commercial/industrial temperature grade (-40°C to 85°C) in a 16-lead MSOP package. Other variants include the C-grade (0°C to 70°C) and H-grade (-40°C to 125°C), available in both tube and tape-and-reel formats.
