LTC2344CUH-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2344CUH-16#PBF is a quad, 16-bit, low-noise successive approximation register (SAR) analog-to-digital converter. It features four simultaneous sampling channels with differential inputs and a wide common mode range. Operating from a single 5V supply, the device incorporates an internal reference and buffer to support SoftSpan input ranges of ±4.096V, 0V to 4.096V, ±2.048V, or 0V to 2.048V per channel. It delivers a typical SNR of 93.4dB and supports pin-selectable SPI CMOS or LVDS serial interfaces.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'C' suffix indicates a commercial temperature range of 0°C to 70°C. Confirm the #PBF designation ensures lead-free compliance. Ensure the QFN-32 package footprint matches the PCB layout requirements for the 5mm x 5mm plastic housing.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous multi-channel acquisition is required. The C-grade variant is suitable for environments between 0°C and 70°C. For wider temperature ranges, consider the I, H, or MP grades. Verify that the OVDD logic level supports the target system's voltage domain.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2344-16 family of quad SAR ADCs. The CUH-16#PBF specifically denotes the commercial grade operating temperature range housed in a 32-lead QFN package. Other variants include the I (–40°C to 85°C), H (–40°C to 125°C), and MP (–55°C to 125°C) temperature grades.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same package and specification are the LTC2344IUH-16#PBF, LTC2344HUH-16#PBF, and LTC2344MPUH-16#PBF, which offer extended temperature ranges.
