ADS117L11IRUKR

Analog To Digital Converters (ADC) Overview

The ADS117L11 is a 16-bit delta-sigma analog-to-digital converter (ADC) featuring data rates up to 400 kSPS with the wideband filter and up to 1067 kSPS with the low-latency filter. It offers an excellent combination of AC performance and DC precision with low power consumption, dissipating 18.6 mW in high-speed mode. The device integrates input and reference buffers to reduce signal loading and includes a configurable digital filter for optimizing AC performance or data throughput. It supports internal or external clocks and features a serial interface with daisy-chain capability.

Analog To Digital Converters (ADC) Feature Summary

• Power-scalable architecture provides two speed modes to optimize data rate, resolution, and power consumption.
• Configurable digital filter allows selection between wideband operation for AC performance and low-latency operation for data throughput.
• Serial interface includes daisy-chain capability to reduce SPI I/O requirements over isolation barriers.
• Input and output data along with register settings are validated by cyclic-redundancy check (CRC) functionality.

Analog To Digital Converters (ADC) Applications

• Data acquisition systems
• Shock and vibration instruments
• Acoustics and dynamic strain gauges
• Analog input modules for factory automation
• Pulse oximetry devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure that any requested variants match the exact pinout and electrical specifications required for the design. Cross-reference the component marking with official documentation to prevent counterfeit parts.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel 16-bit ADC requires high data throughput with flexible filtering options. The choice between wideband and low-latency filters depends on whether AC accuracy or minimal latency is prioritized. Verify that the available supply voltages align with the specified analog and digital power requirements.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS117L family of delta-sigma ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS117L14 but differs in channel count and specific performance characteristics. The RUK package denotes a 20-pin WQFN form factor designed for space-constrained applications.

Analog To Digital Converters (ADC) Replacement Considerations

Check the ADS117L14 for multi-channel requirements. Evaluate the ADS127L11 if higher resolution is needed. Confirm pin compatibility before substituting with other TI ADCs.
