DescripTion
The
LT
®
6657
is a precision voltage reference that combines
robust operating characteristics with extremely low drift
and low noise. With advanced curvature compensation,
this bandgap reference achieves 1.5ppm/°C drift with
predictable temperature behavior, and an initial voltage
accuracy of 0.1%. It also offers 0.5ppm
P-P
noise and very
low temperature cycling hysteresis.
The LT6657 is a low dropout reference that can be powered
from as little as 50mV above the output voltage, up to 40V.
The buffered output supports ±10mA of output drive with
low output impedance and precise load regulation. The
high sink current capability allows operation as a negative
voltage reference with the same precision as a positive
reference. This part is safe under reverse battery condi-
tions, and includes current protection when the output is
short-circuited and thermal shutdown for overload condi-
tions. A shutdown is included to allow power reduction
while enabling a quick turn-on.
The LT6657 is fully specified over the temperature range of
–40°C to 125°C. It is available in the 8-lead MSOP package.

Differences in op amps result in different levels of output signal fluctuations
As shown in the circuit, the peripheral parameters are exactly the same, only the op amp chip is changed.Using OPA2379, the output voltage remains basically unchangedAfter changing to TP1512, the outp...

The 2812 board is a 2-layer board, and it cannot be connected using CCS4.2 and XDS100V2
This is my first time drawing a 2812 board. At first, I forgot to wire CS6&7 (chip select of IS62WV51216BLL-55TLI), and then I flew the wires over. The schematic was drawn according to a version downl...
