The ADS805 is a 20MHz, high dynamic range, 12-bit, pipelined Analog-to-Digital Converter ADC. This converter includes a high-bandwidth track-and-hold that gives excellent spurious performance up to and beyond the Nyquist rate. This high-bandwidth, linear track-and-hold minimizes harmonics and has low jitter, leading to excellent Signal-to-Noise Ratio (SNR) performance. The ADS805 is also pin-compatible with the 10MHz ADS804 and the 5MHz ADS803.
The ADS805 provides an internal reference or an external reference can be used. The ADS805 can be programmed for a 2Vp-p input range which is the easiest to drive with a single op amp and provides the best spurious performance. Alternatively, the 5Vp-p input range can be used for the lowest input-referred noise of 0.09LSBs rms giving superior imaging performance. There is also the capability to set the input range between 2Vp-p and 5Vp-p, either single-ended or differential. The ADS805 also provides an over-range flag that indicates when the input signal has exceeded the converter’s full-scale range. This flag can also be used to reduce the gain of the front end signal conditioning circuitry.
The ADS805 employs digital error techniques to provide excellent differential linearity for demanding imaging applications. Its low distortion and high SNR give the extra margin needed for communications, medical imaging, video, and test instrumentation applications. The ADS805 is available in an SSOP-28 package.
