ADS804E

АЦП, 12 бит, 10 Мвыборок/с, Однополярный, 4.7 В, 5.3 В, SSOP.

The ADS804E is a 12-bit pipelined Analog-to-digital Converter(ADC) 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 SNR performance. The ADC provides an internal reference and can be programmed for a 2Vp-p input range for the best 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 giving superior imaging performance. There is also a capability to set the input range in between the 2Vp-p and 5Vp-p input ranges or to use external reference. The ADC also provides an over-range indicator flag to indicate an input range that exceeds the full-scale input range of the converter. This flag can be used to reduce the gain of the front end gain-ranging circuitry.
