values originally held on C2a and C2b. These values
are then presented to the first stage quantizers and iso-
late the pipelines from the fast-changing inputs. The
wide input bandwidth T/H amplifiers allow the
MAX19192 to track and sample/hold analog inputs of
high frequencies (> Nyquist). Both ADC inputs (INA+,
INB+, INA-, and INB-) can be driven either differentially
or single ended. Match the impedance of INA+ and
INA-, as well as INB+ and INB-, and set the common-
mode voltage to midsupply (VDD/2) for optimum perfor-
mance.
Analog Inputs and Reference
Configurations
The MAX19192 full-scale analog input range is ±VREF
with a common-mode input range of VDD/2 ±0.2V. VREF
is the difference between VREFP and VREFN. The
MAX19192 provides three modes of reference opera-
tion. The voltage at REFIN (VREFIN) sets the reference
operation mode (Table 1).
In internal reference mode, connect REFIN to VDD or
leave REFIN unconnected. VREF is internally generated
to be 0.512V ±3%. COM, REFP, and REFN are low-
impedance outputs with VCOM = VDD/2, VREFP = VDD/2
+ VREF/2, and VREFN = VDD/2 - VREF/2. Bypass REFP,
REFN, and COM each with a 0.33F capacitor.
In buffered external reference mode, apply a 1.024V
±10% at REFIN. In this mode, COM, REFP, and REFN
are low-impedance outputs with VCOM = VDD/2, VREFP =
VDD/2 + VREFIN/4, and VREFN = VDD/2 - VREFIN/4.
Bypass REFP, REFN, and COM each with a 0.33F
capacitor. Bypass REFIN to GND with a 0.1F capacitor.
In unbuffered external reference mode, connect REFIN
to GND. This deactivates the on-chip reference buffers
for COM, REFP, and REFN. With their buffers shut
down, these nodes become high-impedance inputs
(Figure 4) and can be driven through separate, external
reference sources. Drive VCOM to VDD/2 ±10%, drive
VREFP to (VDD/2 +0.256V) ±10%, and drive VREFN to
(VDD/2 - 0.256V) ±10%. Bypass REFP, REFN, and COM
each with a 0.33F capacitor.
For detailed circuit suggestions and how to drive this
dual ADC in buffered/unbuffered external reference
mode, see the
Applications Information section.
Clock Input (CLK)
CLK accepts a CMOS-compatible signal level. Since
the interstage conversion of the device depends on the
repeatability of the rising and falling edges of the exter-
nal clock, use a clock with low jitter and fast rise and
fall times (< 2ns). In particular, sampling occurs on the

REFERENCE MODE
> 0.8 x VDD
Internal reference mode. VREF is internally generated to be 0.512V. Bypass REFP, REFN, and
COM each with a 0.33μF capacitor.
1.024V ±10%
Buffered external reference mode. An external 1.024V ±10% reference voltage is applied to
REFIN. VREF is internally generated to be VREFIN/2. Bypass REFP, REFN, and COM each with a
0.33μF capacitor. Bypass REFIN to GND with a 0.1μF capacitor.
< 0.3V
Unbuffered external reference mode. REFP, REFN, and COM are driven by external reference
sources. VREF is the difference between the externally applied VREFP and VREFN. Bypass REFP,
REFN, and COM each with a 0.33μF capacitor.
