LT6656
1µA Precision Series
Voltage Reference
DESCRIPTION
The LT
®
6656 is a tiny precision voltage reference that
draws less than 1µA of supply current and can operate
with a supply voltage within 10mV of the output voltage.
The LT6656 offers an initial accuracy of 0.05% and tem-
perature drift of 10ppm/°C. The combined low power and
precision characteristics are ideal for portable and battery
powered instrumentation.
The LT6656 can supply up to 5mA of output drive with
65ppm/mA of load regulation, allowing it to be used as
the supply voltage and the reference input to a low power
ADC. The LT6656 can accept a supply voltage up to 18V
and withstand the reversal of the input connections.
The LT6656 output is stable with 1µF or larger output
capacitance and operates with a wide range of output
capacitor ESR.
This reference is fully specified for operation from –40°C
to 85°C, and is functional over the extreme temperature
range of –55°C to 125°C. Low hysteresis and a consistent
temperature drift are obtained through advanced design,
processing and packaging techniques.
The LT6656 is offered in the 6-lead SOT-23 and (2mm
×
2mm) DFN Packages.

王达业 Talking
Complain about this development environment. It does not support the previous ARM simulation tools and you have to buy more tools.
1. The language switching of this software is very simple, but the Chinese localization is not complete, and the debugging interface is still a combination of Chinese and English. 2. The chip supports...
