ADS8578SIPMR

Analog To Digital Converters (ADC) Overview

The ADS8578SIPMR is a high-speed, 14-bit analog-to-digital converter (ADC) featuring eight simultaneous-sampling channels. It utilizes a successive approximation register (SAR) architecture to achieve a maximum throughput of 200 kSPS per channel. The device integrates an analog front-end with programmable gain amplifiers and input clamping for single-ended inputs. It operates with an analog supply voltage ranging from 4.75 V to 5.25 V and a digital supply between 2.3 V and 5.25 V. Key performance metrics include a signal-to-noise ratio of 85.8 dB, differential nonlinearity of 0.2 LSB, and integral nonlinearity of 0.2 LSB. The component is housed in a 64-pin LQFP package and supports parallel or serial digital interfaces.

Analog To Digital Converters (ADC) Feature Summary

• Integrates eight independent ADC channels with simultaneous sampling capability for synchronized data acquisition.
• Includes built-in programmable gain amplifiers and over-voltage protection with input clamping.
• Features flexible digital communication options supporting both parallel and serial interface modes.
• Contains an on-chip low-drift reference voltage source to simplify external circuitry requirements.

Analog To Digital Converters (ADC) Applications

• Multiphase motor control systems
• Industrial automation and process control
• Multichannel data acquisition systems
• Power grid monitoring and protection relays

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix 'IPMR' indicates tape-and-reel packaging distinct from the tray-packaged 'IPM'. Confirm RoHS compliance status through official manufacturer documentation. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Validate pinout compatibility during PCB layout to prevent interface errors.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight-channel simultaneous sampling at 14-bit resolution is required. The integrated PGA reduces external signal conditioning complexity. Consider the SAR architecture for moderate speed applications requiring low power consumption. Verify that the 200 kSPS per channel rate meets system bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments ADS8578S family of high-speed ADCs. It shares architectural similarities with other members like the ADS8584S and ADS8586S but offers specific channel counts and resolution configurations. The IPMR suffix denotes the reel packaging format used for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8578SIPM serves as the tray-packaged equivalent. For higher resolution needs, consider the ADS8598S series. Lower channel count alternatives include the ADS8584S. Verify pin compatibility before substituting with related family members.
