LTC2353ILX-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2353ILX-16#PBF is a dual-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It features buffered differential inputs with a wide common-mode range and supports SoftSpan input configurations for ±10.24V, 0V to 10.24V, ±5.12V, or 0V to 5.12V signals. The device operates at a sampling rate of 550ksps per channel with simultaneous sampling capability. Key electrical specifications include a typical signal-to-noise ratio (SNR) of 94.2dB, integral nonlinearity (INL) of ±1 LSB, and guaranteed no missing codes at 16 bits. It utilizes an internal reference and buffer, supporting both SPI CMOS and LVDS serial interfaces.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel simultaneous sampling SAR ADC with 16-bit resolution and 550ksps throughput per channel.
• SoftSpan technology allows independent per-channel configuration for bipolar or unipolar voltage ranges.
• Integrated picoamp-input analog buffers with 124dB typical CMRR and rail-to-rail overdrive tolerance.
• Pin-selectable digital interface supporting Serial CMOS (1.8V to 5V) and LVDS modes.

Analog To Digital Converters (ADC) Applications

• Programmable Logic Controllers
• Industrial Process Control
• Power Line Monitoring
• Test and Measurement

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific temperature grade suffix when ordering. The 'I' suffix denotes the industrial grade operating range of –40°C to 85°C. Confirm that the required package is the 48-lead LQFP. Ensure supply voltages match the absolute maximum ratings to prevent device damage.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range and flexible input voltage handling without external front-end conditioning. The ILX variant is suitable for industrial environments requiring operation down to –40°C. Consider the H-grade variant if the application demands extended temperature operation up to 125°C.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2353 family of SoftSpan ADCs. The ILX-16 designation specifically identifies the 16-bit resolution version in the industrial temperature grade. It shares architectural similarities with other members of the series but differs in resolution and thermal specifications compared to C-grade or H-grade variants.

Analog To Digital Converters (ADC) Replacement Considerations

For extended temperature requirements, the LTC2353HLX-16#PBF provides identical electrical performance within a –40°C to 125°C range. For lower cost applications within standard commercial temperatures, the LTC2353CLX-16#PBF is available.
