Chip Information
TRANSISTOR COUNT: 372
PROCESS: BiCMOS
Turn-On Time
These devices typically turn on and settle to within
0.1% of their final value in 360µs to 3.2ms, depending
on the device. The turn-on time can increase up to
10ms with the device operating at the minimum
dropout voltage and the maximum capacitive load.
Applications Information
Input Bypassing
For the best transient performance, decouple the input
with a 0.1µF to 1µF ceramic capacitor as shown in the
Typical Operating Circuit. Locate the capacitor as
close to IN as possible. No capacitor is necessary if
transient performance is less important.
Output/Load Capacitance
Devices in the MAX6037 family require an output capaci-
tance in the range of 0.02µF to 1µF for frequency stability.
Temperature Coefficient vs. Operating
Temperature Range for a 1 LSB
Maximum Error
In a data converter application, the reference voltage of
the converter must stay within a certain limit to keep the
error in the data converter smaller than the resolution
limit throughout the operating temperature range.
Figure 2 shows the maximum allowable reference volt-
age temperature coefficient to keep the conversion
error to less than 1 LSB, as a function of the operating
temperature range (T
MAX
- T
MIN
) with the converter
resolution as a parameter. The graph assumes the ref-
erence voltage temperature coefficient as the only
parameter affecting accuracy.
In reality, the absolute static accuracy of a data con-
verter is dependent on the combination of many para-
meters such as integral nonlinearity, differential
nonlinearity, offset error, gain error, as well as voltage
reference changes.
