LMP91200: Resistance value

Amy Luo

Part Number: LMP91200

Hi team,

A customer inquired about the internal resistance of LMP91200. These two resistors are not described in the datasheet. Are the two resistors equal? Can you find its value

Amy,

The resistors are equal. They form a divider for the VREF = VREF/2. They are high impedance to minimize current draw but supply just enough current for the reference.

Amy,

Also the VREF input impedance is 500k.
