MAX6161–MAX6168
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 voltage
options of 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V, 4.5V,
and 5V. They feature a proprietary curvature-correction
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 100μA of
supply current and can source 5mA (4mA for MAX6161)
or sink 2mA of load current. Unlike conventional shunt-
mode (two-terminal) references that waste supply
current and require an external resistor, these devices
offer a supply current that is virtually independent
of the supply voltage (8μA/V variation) and do not
require an external resistor. Additionally, the internally
compensated devices do not require an external compensation
capacitor. Eliminating the external compensation 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-performance, low-voltage systems.
The MAX6161–MAX6168 are available in 8-pin SO
packages.
