LTC2372IUH-16#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2372IUH-16#TRPBF is an 8-channel, 16-bit successive approximation register (SAR) analog-to-digital converter operating at a throughput rate of 500ksps. It features a configurable input multiplexer supporting fully differential, pseudo-differential unipolar, and bipolar ranges. The device includes an onboard 2.048V temperature-compensated reference with a single-shot capable buffer. Key electrical specifications include ±1LSB maximum INL, 96dB typical SNR in fully differential mode, and 27mW typical power dissipation. It utilizes an SPI-compatible serial interface with selectable 1.8V to 5V logic levels and operates from a single 5V supply.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging. Confirm the 'I' grade designation corresponds to the –40°C to 85°C industrial temperature range. Ensure the specific lot date code meets project requirements as manufacturing dates vary by batch.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight channels of 16-bit precision are required at 500ksps per channel. Choose the fully differential input range for high noise immunity applications. Opt for the pseudo-differential modes if interfacing with single-ended sensors requiring unipolar or bipolar voltage ranges. Verify that the 5V analog supply and compatible digital I/O voltages align with the system architecture.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2372-16 family of low-noise, high-speed SAR ADCs. It shares architectural similarities with the LTC2373 but offers a lower 500ksps sampling rate compared to the 1Msps variant. The device is designed for applications requiring multiple channels of simultaneous or sequential conversion with high linearity and low power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2372CUH-16#TRPBF serves as a commercial grade alternative with a 0°C to 70°C operating range. The LTC2372HUH-16#TRPBF provides an extended –40°C to 125°C temperature range. Both variants maintain identical pinouts and electrical performance within their respective temperature specifications.
