Texas Instruments High-Performance Analog Integrated Circuits (ICs) - Data Acquisition - Analog to Digital Converters (ADC) ADS7819UB

The ADS7819UB is a 12-bit analog-to-digital converter (ADC) designed for high-speed applications, featuring an 800 kHz sampling rate. It operates within a ¬±2.5V input range and includes an internal reference voltage of 2.5V. The device is capable of achieving a minimum signal-to-noise and distortion ratio (SINAD) of 70 dB with a 250 kHz input signal. It exhibits low integral non-linearity (INL) of ,Äì0.75 LSB maximum and differential non-linearity (DNL) of ,Äì1 LSB maximum, ensuring accurate conversion performance. The ADS7819UB is housed in a 28-pin SOIC package and is rated for operation over an industrial temperature range of ,Äì40¬8C to +85¬8C. It incorporates a sample-and-hold circuit, clock, and parallel data output with latches, making it suitable for microprocessor interfacing. The device also features inherent overvoltage protection up to ,Äì25V, enhancing its robustness in various applications. Power consumption is specified at 225 mW during operation at the maximum throughput rate.
