ADS8598HIPM

Analog To Digital Converters (ADC) Overview

The ADS8598HIPM is an 18-bit, 8-channel simultaneous-sampling analog-to-digital converter (ADC) from Texas Instruments. It features a successive approximation register (SAR) architecture with a sampling rate of 500 kSPS per channel. The device operates on a single 5-V analog supply (4.75 V to 5.25 V) and a digital supply ranging from 2.3 V to 5.25 V. Key electrical specifications include a signal-to-noise ratio (SNR) of 94 dB, differential nonlinearity (DNL) of 0.5 LSB, and integral nonlinearity (INL) of 2.5 LSB. It supports both parallel and serial interfaces, includes an internal oscillator, and functions within a temperature range of -40°C to +125°C in a 64-pin LQFP package.

Analog To Digital Converters (ADC) Feature Summary

• Eight channels provide true simultaneous sampling capability for multi-phase or synchronized applications.
• Integrated programmable gain amplifier (PGA) allows flexible input range configuration.
• Built-in over-voltage protection safeguards inputs against transient voltage spikes.
• Internal oscillator eliminates the need for external clock generation circuitry.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-precision multi-channel data acquisition
• Medical imaging equipment such as ultrasound and CT scanners
• High-performance test and measurement instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'HIPM' corresponds to the industrial temperature grade (-40°C to +125°C) and the 64-pin LQFP package. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the required interface and pinout configuration before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight independent channels require simultaneous conversion at 18-bit resolution. It is suitable for designs needing integrated PGA and over-voltage protection. Consider power consumption limits, as the device dissipates approximately 88.5 mW. Verify that the system logic levels are compatible with the 2.3 V to 5.25 V digital supply range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8598H family of high-speed, high-resolution ADCs. It shares the same core architecture and functionality as other variants in the series, differing primarily in packaging options and temperature ratings. The HIPM designation specifically identifies the industrial grade version housed in a leaded quad flatpack package.
