Precision, Micropower, Low-Dropout, High-
Output-Current, SO-8 Voltage References
General Description
The MAX6161–MAX6168 are precision, low-dropout,
micropower voltage references. These three-terminal
devices operate with an input voltage range from (VOUT
+ 200mV) to 12.6V and are available with output volt-
age options of 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V,
4.5V, and 5V. They feature a proprietary curvature-cor-
rection circuit and laser-trimmed thin-film resistors that
result in a very low temperature coefficient of 5ppm/°C
(max) and an initial accuracy of ±2mV (max).
Specifications apply to the extended temperature range
(-40°C to +85°C).
The MAX6161–MAX6168 typically draw only 90µA of
supply current and can source 5mA (4mA for
MAX6161) or sink 2mA of load current. Unlike conven-
tional shunt-mode (two-terminal) references that waste
supply current and require an external resistor, these
devices offer a supply current that is virtually indepen-
dent of the supply voltage (8µA/V variation) and do not
require an external resistor. Additionally, the internally
compensated devices do not require an external com-
pensation capacitor. Eliminating the external compen-
sation capacitor saves valuable board area in
space-critical applications. A low-dropout voltage and
a supply-independent, ultra-low supply current make
these devices ideal for battery-operated, high-perfor-
mance, low-voltage systems.
The MAX6161–MAX6168 are available in 8-pin SO
packages.
