ADS8505IBDW

The ADS8505IBDW is a high-performance 16-bit analog-to-digital converter (ADC) from Texas Instruments, utilizing a successive approximation register (SAR) architecture. It samples at 250 kSPS and provides a standard ±10 V input range, making it suitable for a wide variety of data acquisition and industrial control applications. The device integrates a sample-and-hold circuit, reference, and clock, and offers full parallel data output for easy interfacing with microprocessors.

Key electrical specifications include a maximum integral nonlinearity (INL) of ±1.5 LSB and a maximum differential nonlinearity (DNL) of ±1 LSB, ensuring 16-bit no-missing-codes performance. The typical power dissipation is 70 mW at a 250 kSPS sampling rate, and the converter operates from a single 5 V supply. The spurious-free dynamic range (SFDR) is 105 dB at a 250 kHz sample rate, delivering excellent signal fidelity for demanding measurement systems.

The ADS8505IBDW is offered in a 28-pin SOIC package (0.295-inch width) with surface-mount mounting. It is specified for the industrial temperature range of -40°C to 85°C. The device supports both internal and external reference sources, and its pin compatibility with the ADS7805 family allows straightforward upgrades in existing designs. Typical applications include industrial process control, data acquisition systems, medical equipment, and instrumentation.
