ADS8504IBDWR

Analog To Digital Converters (ADC) Overview

The ADS8504IBDWR is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a maximum sampling rate of 250 kSPS and features a parallel data interface. The device supports both single-ended input signals and utilizes an internal or external reference voltage source. It functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 73 dB and differential/integral nonlinearity specifications of +/- 0.45 LSB. The component is housed in a 28-pin TSSOP package and is rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed SAR ADC architecture with a built-in oscillator for simplified system design.
• Supports flexible reference configurations allowing the use of either internal or external voltage references.
• Provides a parallel output interface suitable for direct connection to microprocessors and DSPs.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise analog signal acquisition.
• Medical instrumentation equipment utilizing single-ended sensor inputs.
• Data acquisition modules in automated test and measurement setups.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'W' indicates the tape and reel packaging format compared to the tube variant. Confirm the operating temperature range matches application requirements. Ensure the parallel interface timing constraints align with the host processor capabilities. Validate RoHS compliance status through official manufacturer documentation prior to integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 250 kSPS throughput are sufficient for the application. Choose this part over higher-resolution models if power consumption and pin count are critical constraints. Consider the parallel interface requirement against available microprocessor GPIO resources. Evaluate the need for an internal reference versus external precision references based on system accuracy goals.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS850x family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS8505 and ADS8506 but differs in resolution and interface type. The IBDWR suffix denotes the industrial temperature range and reel packaging, distinguishing it from commercial variants or tube-packaged versions.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8504IBDW serves as the tube-packaged equivalent. For applications requiring serial interfaces, the ADS8506 series offers comparable performance with SPI connectivity. Higher resolution needs may require the ADS8505 or ADS8509 series.
