LTC2344MPUH-16#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2344MPUH-16#TRPBF is a quad-channel, 16-bit successive approximation register (SAR) analog-to-digital converter. It provides simultaneous sampling at 400ksps per channel with differential inputs and a wide common mode range. The device features SoftSpan technology, allowing independent per-channel input range configuration of ±4.096V, 0V to 4.096V, ±2.048V, or 0V to 2.048V. It operates from a 5V analog supply and supports serial interfaces including SPI CMOS (1.8V to 5V) and LVDS. Key performance metrics include a typical SNR of 93.4dB, ±1.25LSB maximum INL, and guaranteed 16-bit resolution without missing codes.

Analog To Digital Converters (ADC) Procurement Notes

Verify the MP suffix indicates military-grade temperature operation (-55°C to 125°C). Confirm the #TRPBF suffix denotes tape and reel packaging. Ensure compatibility with system voltage requirements for VDD (5V) and OVDD (1.8V to 5V).

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous multi-channel acquisition is required. The SoftSpan feature simplifies signal conditioning by accommodating various bipolar and unipolar voltages directly. Choose between CMOS or LVDS interfaces based on noise immunity and bus width constraints.
