CIRCUIT060013 Inverting amplifier with T-network feedback circuit

This design inverts the input signal, VIN, and applies a signal gain of 1000 V/V or 60 dB. The inverting amplifier with T-feedback network can be used to obtain a high gain without a small value for R4 or very large values for the feedback resistors.

CIRCUIT060015 Adjustable reference voltage circuit

This circuit combines an inverting and non-inverting amplifier to make a reference voltage adjustable from the negative of the input voltage up to the input voltage. Gain can be added to increase the maximum negative reference level.

CIRCUIT060074 High-side current sensing with comparator circuit

This high-side, current sensing solution uses one comparator with a rail-to-rail input common mode range to create an over-current alert (OC-Alert) signal at the comparator output (COMP OUT) if the load current rises above 1 A. The OC-Alert signal in this implementation is active low. So when the (...)
