DESCRIPTION
The ADS804 is a high-speed, high dynamic range, 12-bit pipelined
analog-to-digital converter. This converter includes a high-band-
width track/hold that gives excellent spurious performance up to
and beyond the Nyquist rate. This high-bandwidth, linear track/hold
minimizes harmonics and has low jitter, leading to excellent SNR
performance. The ADS804 is also 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 the best spurious performance and ease
of driving. Alternatively, the 5Vp-p input range can be used for the
lowest input referred noise of 0.09 LSBs 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 ADS804 also provides an overrange indica-
tor 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.
The ADS804 employs digital error correction 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 ADS804 is available in 28-Lead SSOP and SOIC
packages.
