The HI1176/HI1179 evaluation board can be used to evaluate
the performance of the HI1176 (8-bit, 20MSPS) and the HI1179
(8-bit, 35 MSPS) analog-to-digital converters (ADC). The board
includes clock driver circuitry, an external reference voltage generator,
data output buffer, and a digital to analog converter (DAC).
The HI1176 and the HI1179 are 8-bit CMOS 2-step A/D converters
designed in 1.4μm and 1.0μm CMOS processes,
respectively. These parts are pin for pin compatible with differences
being the maximum guaranteed clock speed
(20MSPS vs 35MSPS) and the HI1176 has a built in
monostable multivibrator where the HI1179 does not (See
Table 1). The evaluation board is built to be used for both the
HI1176 and the HI1179, therefore the monostable multivibrator
on the HI1176 is not utilized but it is discussed.
The HI1171 (8-bit, 40MHz) DAC is used to reconstruct the
HI1176/HI1179 digital outputs, allowing the user to see the
results of a “complete” 8-bit system. Refer to Table 2 for
more specifications on the HI1171.
