ADS8578SIPM

Analog To Digital Converters (ADC) Overview

The ADS8578SIPM is a 14-bit, high-speed, 8-channel simultaneous sampling analog-to-digital converter (ADC) from Texas Instruments. It features a successive approximation register (SAR) architecture with an integrated analog front-end on each channel, including a programmable gain amplifier (PGA), input clamp, low-pass filter, and ADC driver. The device supports single-ended inputs with pin-programmable bipolar ranges of ±10V or ±5V. It operates with a maximum throughput of 200 kSPS per channel. Key electrical parameters include a signal-to-noise ratio (SNR) of 85.8 dB, differential nonlinearity (DNL) of ±0.2 LSB, and integral nonlinearity (INL) of ±0.2 LSB. The analog supply voltage ranges from 4.75 V to 5.25 V, while the digital supply ranges from 2.3 V to 5.25 V. It is housed in a 64-pin LQFP package and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Applications

• Monitoring and control for power grids
• Protection relays
• Multiphase motor controls
• Industrial automation and controls
• Multichannel data acquisition systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IPM' against the manufacturer's official datasheet to confirm the package type and temperature grade. Ensure compatibility with system voltage levels, as the digital supply accepts 2.3 V to 5.25 V while the analog supply requires 4.75 V to 5.25 V. Confirm that the LQFP-64 footprint matches the PCB design. Check for humidity sensitivity handling requirements during storage and assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight simultaneous sampling channels are required at 14-bit resolution. It is suitable for applications needing high input impedance and overvoltage protection. Compare performance metrics such as SNR and DNL against other SAR ADCs if higher speed or resolution is needed. Consider the integrated PGA and reference if external components can be minimized.

Analog To Digital Converters (ADC) Part Context

The ADS8578SIPM belongs to the ADS8578S series of high-speed, multi-channel ADCs. It shares architectural similarities with other devices in the family, such as the ADS8584S and ADS8586S, which offer different resolutions and channel counts. These devices are designed for industrial applications requiring precise, synchronized data acquisition.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct substitutes like the ADS8584S or ADS8586S if channel count or resolution differences are acceptable. Verify pinout compatibility before replacing. Consult the manufacturer's cross-reference guide for validated alternatives.
