ADS8698IDBTR

Analog To Digital Converters (ADC) Overview

The ADS8698IDBTR is an 18-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It integrates eight single-ended inputs, a programmable gain amplifier, and a multiplexer within a single device. The component operates with an analog supply voltage of 5V and a digital supply range of 1.65V to 5.25V. It supports a sampling rate of 500k samples per second and utilizes a serial peripheral interface (SPI) for data communication. The device is housed in a 38-pin TSSOP package and functions reliably across a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 18-bit SAR ADC with an 8-channel multiplexer and programmable gain amplifier
• Supports high-speed data acquisition at up to 500ksps with SPI digital interface
• Operates on dual power supplies: 5V analog and 1.65V to 5.25V digital domains

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Data acquisition modules for factory automation and monitoring
• Medical instrumentation equipment needing high-resolution analog input processing

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDBTR against official Texas Instruments documentation to confirm tape-and-reel packaging and exact pinout configuration. Ensure compatibility with system voltage levels and SPI timing requirements before integration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 18-bit resolution is required for precision applications alongside multiple single-ended inputs. The integrated PGA reduces external component count compared to discrete solutions. Consider the 38-TSSOP package constraints and thermal management capabilities for high-temperature environments up to 125°C.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS869x family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with models like the ADS8698IDBT but differs in packaging format. The IDBTR designation specifically indicates the tape-and-reel variant intended for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8698IDBT serves as a verified pin-compatible alternative in tube packaging. Verify that the change from tape-and-reel to tube does not impact existing pick-and-place manufacturing workflows or inventory handling procedures.
