Details
MCP6141/2/3/4
In this configuration, the amplifier outputs the sum of
the three input voltages. The ratio of the sum and the
output voltage is defined using the feedback and input
resistors. V
family of amplifiers is stable for noise gain (G
V or higher. The G
amplifier is calculated as shown below:
EQUATION
At a noise gain of 10 V/V, the amplifier bandwidth is
approximately 10 kHz. The bandwidth to quiescent cur-
rent ratio of MCP6141/2/3/4 makes this device an
appropriate choice for battery-powered applications.
