LTC2328CMS-16#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2328CMS-16#TRPBF is a 16-bit successive approximation register (SAR) analog-to-digital converter in a 16-lead MSOP package. It operates from a single 5V supply and features pseudo-differential inputs with true bipolar ranges of ±6.25V, ±10.24V, or ±12.5V. The device achieves a maximum integral nonlinearity of ±1.5LSB with guaranteed no missing codes at 16 bits. It delivers a typical signal-to-noise ratio of 93.5dB and total harmonic distortion of –111dB at a 1Msps sampling rate. Power consumption is 50mW at full throughput, scaling down to 300μW in sleep mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the CMS designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the specific lot matches the required lead-free finish and RoHS compliance standards for the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high voltage bipolar signals require direct digitization without external level shifting. The internal reference simplifies design by eliminating external precision references. Verify that the host interface supports SPI-compatible signaling with logic levels between 1.8V and 5V via the OVDD pin. Consider the 16-lead MSOP package constraints for thermal management and PCB layout.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2328-16 family of high-speed, low-power SAR ADCs. The CMS variant specifically denotes the commercial temperature grade housed in a plastic MSOP package. Other variants include IMS for industrial (-40°C to 85°C) and HMS for extended (-40°C to 125°C) temperatures, all sharing identical electrical specifications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2328IMS-16#TRPBF for wider temperature operation and LTC2328HMS-16#TRPBF for extended industrial environments. These parts share the same electrical characteristics but differ only in operating temperature range and package marking.
