LTC2344CUH-16

Analog To Digital Converters (ADC) Overview

The LTC2344CUH-16 is a quad, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It features four simultaneous sampling channels with a data rate of 400 kSPS per channel. The device operates with a digital supply voltage of 5 V and supports differential inputs. Key performance metrics include a signal-to-noise ratio (SNR) of 93.4 dB, an spurious-free dynamic range (SFDR) of 115 dB, and integral nonlinearity (INL) of 1.25 LSB. It is housed in a QFN-32 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CUH' against official Analog Devices documentation to confirm the commercial temperature grade (-40°C to +85°C) and tube packaging format. Ensure compatibility with 5 V digital logic levels and check for RoHS compliance status in the latest datasheet revision before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling across four channels is required at 16-bit resolution. Compare SNR and SFDR specifications against system noise floors. Verify that the 5 V digital interface aligns with the host microcontroller or FPGA I/O standards. Consider thermal management due to 500 mW power dissipation in the QFN-32 package.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2344 family of high-speed, low-power SAR ADCs. The 'C' indicates commercial temperature range, while 'UH' denotes the QFN-32 package style. The '-16' specifies the 16-bit resolution variant. This series is designed for applications requiring multiple synchronized analog inputs without interleaving artifacts.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the LTC2344IUH-16 for extended industrial temperature ranges. Cross-family substitution requires careful evaluation of pinout compatibility, power supply requirements, and serial interface timing differences.
