ADS8509IDWR

Analog To Digital Converters (ADC) Overview

The ADS8509IDWR is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input configuration and operates with an SPI-compatible serial interface. The device supports sampling rates up to 250 kSPS and 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 (SNR) of 88 dB, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±2 LSB. It is housed in a 28-pin TSSOP package and operates across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal oscillator eliminates the need for external clocking circuitry.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IDWR' corresponds to the tape-and-reel packaging format rather than tube packaging when sourcing components. Confirm that the order quantity aligns with standard reel sizes to avoid partial reel handling issues. Ensure compatibility with the required operating temperature range and voltage specifications during the procurement phase.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications demanding 16-bit resolution at moderate speeds. Consider the single-ended input limitation if differential signaling is required. Evaluate the power consumption against system thermal constraints, as the device dissipates approximately 155 mW under typical operating conditions.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8509 family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with other devices in the series but differs in pinout and packaging options. The IDWR designation specifically identifies the industrial-grade version in a tape-and-reel format suitable for automated surface-mount assembly processes.
