ADS8331IBPW

Analog To Digital Converters (ADC) Overview

The ADS8331IBPW is a low-power, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-ended, 4-channel multiplexer input and supports sampling rates up to 500 kSPS. The device operates with an analog supply voltage range of 2.7 V to 5.5 V and a digital I/O supply range of 1.65 V to VA. It utilizes a flexible SPI-compatible serial interface with SCLK frequencies up to 40 MHz when powered at 5 V. The component is housed in a 24-pin TSSOP package and is rated for operation within the industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 4-channel multiplexer with automatic or manual channel selection capabilities
• Supports daisy-chaining for multiple converters via a compatible serial interface
• Includes on-chip conversion clock and programmable end-of-conversion interrupt
• Features deep sleep and auto NAP modes for optimized power consumption

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Medical instrumentation
• Data acquisition systems
• Communications equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IBPW corresponds to the industrial temperature grade (-40°C to +85°C) and the 24-pin TSSOP package configuration. Confirm that the ordering part number matches the exact pinout and electrical specifications required for the target design. Ensure compatibility with the intended SPI controller interface levels before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 500 kSPS throughput are required for multi-channel signal acquisition. Consider the ADS8332 if eight channels are needed instead of four. Evaluate the power budget against the 8.7 mW consumption in Auto-NAP mode at 250 kSPS. Ensure the system can accommodate the external reference requirement and the specified analog and digital supply voltage ranges.

Analog To Digital Converters (ADC) Part Context

The ADS8331 belongs to the ADS833x family of low-power, high-speed SAR ADCs from Texas Instruments. This series includes the ADS8332, which shares the same core architecture but provides an 8-channel multiplexer. Both devices are designed for applications requiring precise data conversion with flexible power management options and robust serial communication interfaces.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8332 serves as a functional alternative within the same family, offering identical performance characteristics but with an 8-channel multiplexer instead of 4. Designers requiring more input channels should verify pinout compatibility and software configuration changes necessary for the additional inputs.
