Texas Instruments ADS804EG4

Description
The ADS804 is a high-speed, high dynamic range, 12-bit, pipelined Analog-to-Digital (A/D) converter. It includes a high-bandwidth track-and-hold for excellent spurious performance up to and beyond the Nyquist rate. The ADS804 is pin-compatible with the 5MHz ADS803 and the 20MHz ADS805.
The ADS804 provides an internal reference and can be programmed for a 2Vp-p input range for optimal spurious performance and ease of driving. Alternatively, the 5Vp-p input range can be used for the lowest input referred noise of 0.09LSBs rms, resulting in superior imaging performance. It also allows for setting the input range between 2Vp-p and 5Vp-p or using an external reference.
The ADS804 features an over-range indicator flag to indicate an input range exceeding the full-scale input range of the converter. This flag can be used to reduce the gain of the front end gain-ranging circuitry.
The ADS804 employs digital error correction techniques for excellent differential linearity in demanding imaging applications. Its low distortion and high SNR provide the necessary margin for communications, medical imaging, video, and test instrumentation applications.
