The ADS8484IBRGZT is an 18-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments, offering a maximum sampling rate of 1.25 MSPS. It accepts a pseudo-bipolar fully differential input signal and provides a high-speed parallel interface supporting 8-, 16-, or 18-bit bus transfers. The device achieves excellent dynamic performance with a typical signal-to-noise ratio (SNR) of 98.5 dB, total harmonic distortion (THD) of -117 dB, and spurious-free dynamic range (SFDR) of 120 dB. DC accuracy includes integral nonlinearity (INL) of ±1.5 LSB typical and differential nonlinearity (DNL) of +0.8/-0.6 LSB typical.
The ADC operates from an analog supply of 4.75 V to 5.25 V and a digital supply of 2.7 V to 5.25 V, with typical power consumption of 235 mW. It includes an onboard reference and reference buffer, and supports both external and internal reference modes. The device is specified over the industrial temperature range of -40°C to 85°C and is housed in a 48-pin VQFN package with exposed pad (7 mm x 7 mm) for surface-mount assembly.
Typical applications include medical instruments, optical networking, transducer interfaces, high-accuracy data acquisition systems, and magnetometers. The ADS8484IBRGZT is part of the precision ADC family and is not recommended for new designs (NRND).
