GENERAL DESCRIPTION
The XRD8799 is a flexible, easy to use, precision 10-
bit analog-to-digital converter with 8-channel mux that
operates over a wide range of input and sampling
conditions. The XRD8799 can operate with pulsed
"on demand" conversion operation or continuous
"pipeline" operation for sampling rates up to 2MHz.
The elimination of the S/H requirements, very low
power, and small package size offer the designer a
low cost solution. No sample and hold is required for
CCD applications up to 2MHz, or multiplexed input
applications when the signal source bandwidth is lim-
ited to 100kHz. The input architecture of the
XRD8799 allows direct interface to any analog input
range between AGND and AVDD (0 to 1V, 1 to 4V, 0 to
5V, etc.). The user simply sets VREF(+) and VREF(-) to
encompass the desired input range.
Scaled reference resistor taps @ 1/4 R, 1/2 R and 3/4
R allow for customizing the transfer curve as well as
providing a 1/2 span reference voltage. Digital out-
puts are CMOS and TTL compatible.
The XRD8799 uses a two-step flash technique. The
first segment converts the 5 MSBs and consists of
autobalanced comparators, latches, an encoder, and
buffer storage registers. The second segment con-
verts the remaining 5 LSBs.
When the power down input is "high", the data out-
puts DB9 to DB0 hold the current values and VREF(-) is
disconnected from VREF1(-). The power consumption
during the power down mode is 0.1mW.
