ADS8332IBPWR

Analog To Digital Converters (ADC) Overview

The ADS8332IBPWR is a low-power, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features an 8-channel unipolar input multiplexer 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 interface supply ranging from 1.65 V to VA. Key electrical parameters include a typical integral nonlinearity (INL) of ±1.2 LSB at 2.7 V and ±1 LSB at 5 V, with a maximum of ±2 LSB. At 5 V and 1 kHz input frequency, it achieves a signal-to-noise ratio (SNR) of 91.5 dB, spurious-free dynamic range (SFDR) of 101 dB, and total harmonic distortion (THD) of -100 dB. Power consumption is 8.7 mW in Auto-NAP mode at 250 kSPS and 14.2 mW at 500 kSPS.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel single-ended input multiplexer with on-chip sample-and-hold circuitry for efficient multi-point data acquisition.
• Supports daisy-chain operation via a high-speed, SPI-compatible serial interface allowing multiple devices to share the clock line.
• Offers flexible power management through Nap, Deep, and Auto-Nap modes to minimize current consumption during idle periods.

Analog To Digital Converters (ADC) Applications

• Programmable Logic Controller (PLC) input modules
• Industrial process control systems
• Medical instrumentation
• Data acquisition systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IBPWR' against the manufacturer's latest datasheet to confirm package type and temperature grade. Ensure the ordering part number matches the required tape-and-reel quantity specifications. Cross-reference the component marking with official identification guides to prevent counterfeit substitution.

Analog To Digital Converters (ADC) Selection Notes

Select this model when eight single-ended channels are required within a compact footprint. Compare performance against the ADS8331 if only four channels are needed. Verify that the system voltage levels align with the 1.65 V to 5.5 V digital interface range and that the 500 kSPS throughput meets application bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS833x family of low-power, 16-bit SAR ADCs. It shares the same core architecture as the ADS8331 but provides double the channel count. The family is designed for applications requiring moderate speed and high resolution with minimal power dissipation.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8331IBPWR is a compatible alternative offering identical performance characteristics with a 4-channel multiplexer instead of 8. Verify pin compatibility and software configuration differences before substituting.
