LTC2337HMS-18#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2337HMS-18#TRPBF is an 18-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 5V supply and features fully differential inputs with a true bipolar range of ±10.24V. The device achieves a throughput rate of 500ksps with no pipeline delay or cycle latency. Key electrical specifications include a maximum integral nonlinearity (INL) of ±4LSB, guaranteed 18-bit resolution without missing codes, and a typical signal-to-noise ratio (SNR) of 100dB at a 2kHz input frequency. Power consumption is typically 35mW at full sampling rate, scaling down to 300μW in sleep mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF confirms tape and reel packaging for this specific part number. Confirm the H-grade designation indicates an extended operating temperature range of –40°C to 125°C. Ensure compatibility with the required 16-lead MSOP package format for your PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high voltage differential inputs up to ±10.24V are required without external attenuation circuitry. The internal reference buffer simplifies design by providing a 4.096V output for the specified input range. Consider the 35mW power dissipation at 500ksps and the availability of nap and sleep modes for power-sensitive applications.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2337-18 family of low noise, high speed SAR ADCs. The HMS-18 variant specifically denotes the 16-lead plastic MSOP package with an extended industrial temperature range. The #TRPBF suffix indicates lead-free finish and tape and reel shipping configuration.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same series include LTC2337IMS-18#TRPBF for commercial temperature range (0°C to 70°C) and LTC2337CMS-18#TRPBF for lower temperature requirements. Verify that the thermal performance of the MSOP package meets the junction temperature limits for the intended application environment.
