Figure 2. Typical Operating Circuit
The following errors are defined:
+FS error = top of ladder offset voltage
=
(+FS - VST + 1LSB)
-FS error = bottom of ladder offset voltage
=
(-FS - VSB - 1LSB)
where the +FS (full-scale) input voltage is defined as the
output transition between 11 1111 1110 and 11 1111 1111,
and the -FS input voltage is defined as the output transi-
tion between 00 0000 0000 and 00 0000 0001 (Table 2).
Analog Input
VIN is the analog input. The full-scale input range will
be 80% of the reference voltage, or ±2V with VFB =
-2.5V and VFT = +2.5V.
The analog input’s drive requirements are minimal
when compared to conventional flash converters. This
is due to the MAX1160’s extremely low (5pF) input
capacitance and very high (300k
) input resistance.
For example, for an input signal of ±2Vp-p with a
10MHz input frequency, the peak output current
required for the driving circuit is only 628μA.
Cloc k Input
The MAX1160 is driven from a single-ended TTL input
(CLK). The CLK pulse width (t
pwH
) must be kept
between 20ns and 300ns to ensure proper operation of
the internal track/hold amplifier (Figure 1a). When oper-
ating the MAX1160 at sampling rates above 3Msps, it is
recommended that the clock input duty cycle be kept at
